Citroën Grand C4 SpaceTourer vs. Renault Grand Scénic: Complete comparison 2026

The Citroën Grand C4 SpaceTourer, previously sold under the much better-known name Grand C4 Picasso, is a highly comfortable and exceptionally spacious family MPV that bets on bold design and maximum practicality for larger families. Its direct competitor is the Renault Grand Scénic, a stylish pioneer of this segment that attracts customers with dynamic shapes, typical large wheels, and a cleverly designed variable interior. Let's take a detailed look at which of these two popular French cars represents a better, more reliable, and more advantageous choice on the used car market for your daily travels.

When comparing the exterior dimensions of these two popular family vehicles, it is essential to choose the correct generations that currently form the core of the market for roughly four-year-old used cars. While the Citroën Grand C4 SpaceTourer was sold in its last generation between 2018 and 2021, for the Renault Grand Scénic, we must choose the adequate fourth generation (produced until 2022) for a meaningful comparison, not models from previous decades. Both cars fall into the category of spacious MPVs, but even at first glance at their outer outlines, a different approach can be traced. While Citroën maintains a more traditional, millimetre-perfect boxy silhouette, Renault has opted for more dynamic proportions with slight crossover elements. Dimensional characteristics thus play a crucial role in how well the car fits into your garage and how it stands up in the daily urban jungle.

In terms of absolute numbers, the Renault Grand Scénic claims more space on the road, having a slight edge in all three main axes. With a total length of 4634 mm, it is exactly 32 mm longer than the Citroën Grand C4 SpaceTourer (4602 mm), while also being significantly 40 mm wider (1866 mm compared to 1826 mm) and 22 mm taller (up to 1660 mm vs. 1638 mm). This overall larger body gives the Renault a more confident stance on the road and brings a slightly more robust appearance, which you will appreciate in terms of a sense of safety. In contrast, the Citroën's more compact dimensions are a huge advantage for drivers who struggle with space daily. In particular, the 4-centimetre smaller width of the car means invaluable extra millimetres when opening doors in narrow underground garages or at shopping centres, making the Citroën a slightly more accommodating car for intensive city use.

An important indicator that says a lot about the interior layout is the distance between the front and rear axles. The wheelbase of the Renault Grand Scénic is 2804 mm, surpassing the Citroën's value of 2785 mm by 19 mm. In practice, the Renault's longer wheelbase contributes to slightly better directional stability on motorways and promises a theoretical advantage in longitudinal legroom in the second and third rows of seats. Citroën, on the other hand, proves that absolute numbers aren't everything – it balances a slightly shorter wheelbase with top-notch space packaging and subjectively better agility. The Renault's longer wheelbase thus makes sense especially for families travelling primarily on long routes, while the Citroën's slightly shorter chassis offers a perfect balance between solid interior space and the necessary nimbleness for frequent city driving.

When choosing a family car approximately four years old, luggage capacity is often the most important criterion that determines daily usability. For families, a larger boot means less stress when packing strollers, sports equipment, or bulky shopping. Both the Citroën Grand C4 SpaceTourer and the Renault Grand Scénic are staples of the used MPV market, and both models aim for maximum practicality. Although they share a similar French philosophy focused on comfort and family, their approach to interior space differs slightly, which can have a significant impact on buyers.

In terms of exact figures, the Citroën Grand C4 SpaceTourer in a five-seat configuration (with the third row of seats folded) has a standard boot volume of 645 litres, which can be increased to 704 litres thanks to the sliding second row. If you fold all the rear seats, you get a huge van with a maximum volume of 2181 litres. The competing fourth-generation Renault Grand Scénic offers an excellent 718 litres in the purely five-seat version, but the seven-seat variant is much more common on the used car market. With the third row of seats folded into the floor, it provides a basic volume of 533 litres. When the second and third rows of seats are fully folded, this Renault reaches a maximum capacity of 1737 litres.

In practice, these differences mean that the Citroën, thanks to its boxier body and lower loading sill, is the absolute champion in carrying cargo. Its maximum capacity literally offers space for several extra suitcases, making it an ideal partner sufficient for weekend shopping and longer holidays with the whole family. Renault Grand Scénic, on the other hand, sacrificed part of its absolute volume in favour of an attractive, almost crossover-like design with large twenty-inch wheels. The conclusion for those interested in a used car is therefore clear: if your absolute priority is moving large objects and uncompromising interior space, the Citroën Grand C4 SpaceTourer will be the more logical choice. However, if a slightly smaller but still very practical boot wrapped in a more stylish coat is enough for you, the Renault Grand Scénic will easily satisfy your family needs.

The ability to tow a trailer is often a decisive parameter for family MPVs, significantly expanding their practicality and overall flexibility. While the Citroën Grand C4 SpaceTourer (in its 1st generation) allows a braked trailer with a weight starting at 1,150 kg and reaching a very solid 1,750 kg to be attached to the tow bar, the competing Renault Grand Scénic of a comparable age (i.e., 4th generation) slightly surpasses it, as its maximum limits reach 1,800 to 1,850 kg. The weight of an unbraked trailer for both cars logically hovers around the legal limit, specifically in the range of 695 to 750 kg.

A more detailed comparison reveals significant differences across individual engine versions. The standard towing capacity of base versions (such as the PureTech 130 in the Citroën) is a more modest 1,150 to 1,400 kg. It is also worth noting that for some newer Citroën model years (especially 2020–2021), the capacity was limited, likely due to meeting emission limits, even for the popular BlueHDi 130 engine, where the value dropped to 1,200 kg. However, these lower weights are still perfectly sufficient for weekend shopping or longer holidays, for example with a light utility trailer or a smaller folding camper. Conversely, the maximum limits of the top diesel versions (e.g., BlueHDi 150) can confidently handle heavy caravans, which for families on the road means invaluable space for several extra suitcases and maximum travel comfort.

In conclusion, if towing bulkier loads is more of an occasional matter for you, both cars will serve you excellently. However, if you plan on regularly crisscrossing Europe with a heavy caravan, powerful diesel engines are a necessity in this regard, and Renault provides a slight technical edge here in its newer generation.

Note: Since the database for the Renault Grand Scénic model only contains historical data for the 2nd generation from 2004–2009, which does not correspond in age to the market for roughly four-year-old used cars, these outdated values are not included in the table below for the sake of an objective comparison.

When choosing a family MPV on the market for roughly four-year-old used cars, the range of engines plays a key role, as it directly affects fuel consumption, the overall dynamics of the car, and reliability when fully loaded with passengers and luggage. Both the Citroën Grand C4 SpaceTourer and the Renault Grand Scénic offer modern turbocharged units, but with very different technical approaches. Citroën traditionally relies on exceptionally fuel-efficient diesel engines (1.5 BlueHDi and 2.0 BlueHDi) paired with a very smooth-shifting eight-speed torque converter automatic transmission (EAT8). The petrol choice here is the 1.2 PureTech three-cylinder. Renault, on the other hand, scores with the excellent 1.3 TCe petrol four-cylinder (developed in cooperation with Mercedes-Benz), which offers great refinement and plenty of power across the entire rev range. The diesel alternative at Renault is the updated 1.7 Blue dCi engines, which rely on responsive EDC dual-clutch automatics. For highway travelers with high annual mileage, the diesel Citroën will be slightly more suitable thanks to its torque converter automatic, while families with lower annual mileage and more frequent city driving will be much better served by the Renault with its refined and dynamic 1.3 TCe petrol engine.

Citroën Grand C4 SpaceTourer Engines

The Citroën Grand C4 SpaceTourer offers a clear range of powertrains, which, however, changed quite quickly due to increasingly strict emission standards. If you are looking for a roughly four-year-old used car, you will primarily come across the 1.2 PureTech 130 petrol three-cylinder and the exceptionally efficient 1.5 BlueHDi 130 diesel units or the more powerful and highly sought-after 2.0 BlueHDi 160. It is essential to mention that for Citroën, a number of engines dropped out of the range relatively early. The available data clearly shows that older engines such as the 1.6 BlueHDi 120 and 2.0 BlueHDi 150 diesels, or the 1.6 THP 165 petrol, were discontinued during 2018. The powerful 1.6 PureTech 180 petrol engine was then only available for a very short time during 2019. Fortunately, most of the more modern engines on the young used car market are already available with the reliable eight-speed torque converter automatic (EAT8), which successfully replaced the older and slower six-speed EAT6.

Renault Grand Scénic Engines

In the case of the Renault Grand Scénic, it is essential to focus on the relevant 4th generation, as in the context of the market for roughly four-year-old used cars, the older 2nd generation from 2004–2009 is no longer relevant. From the perspective of power units, the modern Grand Scénic relies primarily on the excellent 1.3 TCe petrol four-cylinder. This is available in three power levels and has earned a reputation on the market as a highly reliable unit with above-average refinement. For diesel fans, the automaker has been serving the newer 1.7 Blue dCi engines (with outputs of 88 kW and 110 kW) since 2018, which fully replaced the earlier 1.5 dCi and 1.6 dCi versions in the range. While competitor Citroën uses a torque converter automatic, Renault opted for EDC dual-clutch transmissions (with six or seven speeds) for its automatic versions. While these can ensure almost lightning-fast shifts during acceleration, they are not as smooth as the competitor's classic torque converter when crawling in traffic jams or parking.

Choosing the right engine is absolutely crucial for long-term satisfaction with a family MPV, which is why our recommendations are based on real-world experience, operational reliability, and actual fuel consumption of roughly four-year-old used cars. While the traditional strong and economical diesel school dominates the 2018–2021 Citroën Grand C4 SpaceTourer, the situation at Renault Grand Scénic has turned in favour of modern petrol units. Although you will find popular older engines from the second generation in the Renault database (such as the 1.9 dCi or 1.6 16V available until 2009), these units have long since ceased to be offered in roughly four-year-old models. Instead, we will focus on modern, cleaner, and much more advanced engines that make the most sense in today's market for nearly new used cars.

For the Citroën Grand C4 SpaceTourer, we recommend: 2.0 BlueHDi 160 (120 kW)

This two-litre diesel is the absolute best choice for a fully loaded seven-seater MPV. It offers a great balance between dynamics, pulling power, and long-term mechanical durability. Compared to the smaller and more common 1.5 BlueHDi engine on the market, this powerhouse does not suffer from undersized camshaft timing chains, which can cause problems in the smaller unit. With its 400 Nm of torque, it can handle motorway climbs even with a full car, with a real-world consumption of around 6 litres per 100 km. Furthermore, the standard eight-speed EAT8 automatic from Japan's Aisin shifts very smoothly and constantly keeps the engine in the ideal rev range.

• Why it's the best choice: It provides a huge power reserve for safe overtaking, handles heavy loads without problems, and the mechanical basis of the engine itself is among the most reliable on the market.
• Known risks and their solutions: The biggest weakness of this engine is the SCR emission system – specifically the AdBlue tank with an integrated pump, which is at risk of failure due to urea crystallization. How to check it: During the test drive, carefully monitor the instrument cluster. Any emission system warning (engine light and wrench with a countdown of kilometres until the start is blocked) indicates an expensive problem. Before buying, also always check the service history to see if the tank has already been replaced with a modified version in the past.
• Who it's suitable for: The engine is ideal for drivers who regularly cover long motorway distances, or for large families making maximum use of the car's capacity. It is not very suitable for purely urban driving due to the risk of rapid DPF filter clogging.

For the Renault Grand Scénic, we recommend: 1.3 TCe 140 (103 kW)

Although MPVs used to be typical cars for diesel engines, for a roughly four-year-old fourth-generation Grand Scénic, the 1.3 TCe turbocharged petrol four-cylinder, developed in cooperation with Mercedes-Benz, is by far the safest choice. It offers a perfectly adequate 103 kW of power and 240 Nm of torque, while real-world consumption in combined operation stays around a solid 7 l/100 km. Unlike the problematic older generations of TCe engines (e.g., 1.2 TCe), this unit has a reliable timing system and stands out for its refined and quiet operation.

• Why it's the best choice: It is characterized by very fast warming up to operating temperature, there is no risk of expensive failures of complex diesel emission systems, and overall it offers a very pleasant mix of reliability and refinement.
• Known risks and their solutions: A typical risk for direct-injection engines is carbon buildup on the intake valves during frequent very short trips, and occasional coolant leaks around the thermostat housing can also occur with this unit. How to check it: Under the hood, thoroughly visually check the coolant level in the expansion tank (it must not be below the minimum mark). During a completely cold start, listen carefully to the operation – the engine must start smoothly and maintain steady running without vibrations or fluctuating revs.
• Who it's suitable for: It is a perfect all-rounder that will easily and without consequences survive daily school runs, but will not disappoint you even during a fully loaded trip for a summer family holiday.

Official fuel consumption figures provided by manufacturers often differ significantly from reality, especially for large and heavy family MPVs where aerodynamics, a large frontal area, and overall vehicle load play a crucial role. While official laboratory methodologies promised miraculous figures for these vehicles, often starting with a four, practice shows a different picture. To get an accurate idea of how much fuel these roughly four-year-old vehicles (from 2018–2022) actually require, we rely on independent data from drivers themselves collected on the popular independent portal Spritmonitor.de.

Data source: Spritmonitor.de

Looking at real-world data, it is clear that diesel engines are still the most logical choice for these large family cars in terms of efficiency. Entry-level diesel engines (1.5 BlueHDi for Citroën and 1.5 dCi for Renault) can move even a fully loaded MPV with a very reasonable appetite of just over 5.5 liters per 100 kilometers. Conversely, petrol engines exhibit the classic ailment of small turbocharged units in large cars. Both the 1.2 PureTech three-cylinder from Citroën and the more refined 1.3 TCe four-cylinder from Renault struggle to stay below the 7-liter mark in real-world traffic. Once you load the cars with a family and hit the highway, the consumption of both small petrol engines can rise steeply.

For the average user, this leads to a clear recommendation based on how the vehicle is used. If you spend most of your time driving around town, taking children to school, and on short trips, the petrol versions make sense. This way, you avoid potential problems with a clogged diesel particulate filter (DPF) or the more complex AdBlue injection system, even though you will pay slightly more at the pump. However, for families who primarily use the vehicle for long highway journeys, summer holidays by the sea, or regular weekend trips, diesel variants are the clear favorite. They significantly reduce operating costs while offering better torque for safer overtaking in a fully loaded car.

So, will fuel consumption be the main deciding factor between these two French rivals? Probably not. The real-world values of both models with comparable engines are so close that you will hardly feel the difference in your wallet. While Citroën narrowly wins the battle for the most efficient entry-level diesel with its 1.5 BlueHDi, Renault counters with the more mature 1.3 TCe petrol four-cylinder, which offers much better sound and dynamic performance for similar consumption as Citroën's three-cylinder. The decision will therefore likely come down to a preference for exterior design, interior layout, and the current condition of a specific unit on the used car market.

Both models, the Citroën Grand C4 SpaceTourer and the Renault Grand Scénic, are among the last classic family MPVs on the European market. Their production ended around 2022, which means that used cars approximately four years old (from the end of production) are currently in high demand as they represent an ideal compromise between modern equipment and an acceptable price.

When looking at vehicles from 2021 to 2022, the price ranges of both competitors largely overlap. However, Citroën manages to maintain a slightly higher price ceiling thanks to the enduring popularity of its more powerful diesel engines.

Used Car Price Comparison (approx. 4 years old)

(Note: Prices depend on the odometer reading, chosen equipment, and specific engine.)

Citroën Grand C4 SpaceTourer: King of the Diesel Long-Haulers

For four-year-old used Citroëns, the chosen engine plays a crucial role. The cheapest units with a price tag around €12,000 and mileage over 150,000 km usually hide the entry-level 1.5 BlueHDi (96 kW) diesel engine or the 1.2 PureTech petrol three-cylinder under the hood.

However, if you are looking for the top specification with the highly sought-after and reliable 2.0 BlueHDi (120 kW) engine paired with an eight-speed automatic transmission and mileage under 100,000 km, expect prices to easily cross the €20,000 mark. This version holds its value exceptionally well – on the used car market, it is one of the best and most efficient diesel units for a fully loaded family car.

Renault Grand Scénic: The Petrol Choice with Excellent Value for Money

The situation on the used car market for Renault is slightly different. The end of production for the Grand Scénic was marked by a retreat from diesels. Therefore, among four-year-old cars, you will most frequently encounter the very successful 1.3 TCe four-cylinder petrol engine (in 103 kW or 118 kW versions), which was developed in cooperation with Mercedes-Benz.

Vehicles with this engine and mileage between 100,000 and 140,000 km commonly sell for a pleasant €12,000 to €14,000. Compared to the Citroën, Renault thus offers a somewhat more affordable entry into the world of modern seven-seater MPVs. Occasionally, you can also find the 1.7 Blue dCi diesel engine on the market, with prices in a similar range, but the overall supply in dealerships is much more limited.

What to Choose from a Value Perspective?

• If you are looking for a car for long highway journeys and summer holidays: The Citroën with the two-liter diesel is more expensive to purchase, but it makes the most sense for these purposes, and its residual value will decline only very slowly in the coming years.
• You often drive suburban routes and take children to school: The petrol Renault Grand Scénic 1.3 TCe offers an absolutely great price-to-value ratio, while its purchase price will be significantly friendlier to the family budget. Moreover, the quiet petrol engine will not suffer on short trips.

Both of these popular family cars achieved the prestigious maximum five-star rating in Euro NCAP safety tests in their time. However, for a correct assessment of their safety, it is necessary to take into account the broader context and, above all, the year of their testing. The safety protocols of the independent Euro NCAP organisation are constantly evolving and become stricter almost every year. For this reason, percentage results from different years cannot be directly compared – newer methodologies include significantly more demanding frontal impact simulations, stricter measurements of cervical spine injuries, or the detection of cyclists and pedestrians at intersections, which were completely absent from older assessments.

The Citroën Grand C4 SpaceTourer (then still tested under the name Grand C4 Picasso) underwent crash tests as early as 2013. Although it clearly excelled in safety at the time and met all the criteria of the day, its safety certification officially expired in January 2020. This is common Euro NCAP practice for older vehicles that are expected to no longer meet modern and significantly stricter standards.

In contrast, the Renault Grand Scénic underwent crash tests in 2016, following significantly newer and more demanding protocols. Its testing already took into account advanced trials of autonomous emergency braking (AEB) systems. Renault gained valuable points here by being one of the first in its segment to offer pedestrian detection combined with emergency braking as standard equipment.

The percentages obtained clearly reflect the different levels of difficulty of the two testing eras. Citroën benefited from the relatively benevolent 2013 standards, earning a generous 81% for safety assistance systems. Renault, on the other hand, "paid the price" for the stricter 2016 methodology, which resulted in only 59% for assistants, even though its actual technological equipment is much more advanced. Despite the stricter test criteria, however, Renault achieved an excellent 90% for adult occupant protection, surpassing the 86% of Citroën's older body structure. The results for the protection of vulnerable road users correspond in both models to the design limits of MPV category vehicles at the time, characterized by a higher and steeper front end.

The overall comparison clearly shows that although both models will protect you very well on the road, the Renault Grand Scénic offers a more modern and comprehensive safety package. Its crumple zones and assistance systems have passed the sieve of more demanding criteria, the car has more advanced active protection against collisions with pedestrians, and from a homologation perspective, it provides a noticeably higher and more up-to-date safety standard in today's traffic.

In addition to standard equipment, each model offers several unique features, and both cars prove that a family MPV can provide much more than just basic spatial standards. However, each manufacturer approaches added value and everyday practicality in a completely different way.

Citroën Grand C4 SpaceTourer: Light, Space, and Lounge Comfort

Citroën focused on maximum airiness, comfort on long journeys, and flexibility of the interior layout for this model, drawing inspiration from luxury lounges.

• Panoramic windscreen: An iconic feature of the model. The windscreen extends deep into the roof, which not only optically enlarges the interior but also provides an unrivalled view forward and excellently illuminates the cabin. The sun visors can be moved on rails according to current needs.
• Lounge-style seats: In higher trim levels, Citroën offers a "Relax" passenger seat with an electrically extendable calf rest. Together with the massage function of the front seats and special headrests, the car provides comfort approaching first class on an aeroplane.
• Three full-size rear seats: The second row consists of three independent and equally wide seats. They can be individually slid, reclined, and folded flat. What is crucial for families – child car seats can be easily placed on all three thanks to three Isofix anchor points.
• Dual digital display: The dashboard is dominated by two screens. The lower 7-inch touchscreen is used to control the air conditioning and multimedia, while the massive 12-inch panoramic HD display under the windscreen replaces traditional dials and allows for wide personalisation of the displayed information.
• Clever storage spaces: A removable centre console between the front seats is available, as well as practical compartments hidden in the floor in front of the second row of seats and aviation-style tray tables with integrated lights for rear passengers.

Renault Grand Scénic: Innovative Design and Smart Modularity

Renault approached the fourth generation of the Scénic model with courage, combining the world of MPVs with crossover design elements and adding several highly original technological solutions.

• Standard 20-inch wheels: A true rarity in its class. All versions of the Grand Scénic are fitted from the factory with 20-inch alloy wheels with tyres of a specific profile (195/55 R20). This solution improves aerodynamics, reduces rolling resistance, and gives the car an unmistakable, dynamic look without the need to pay extra for larger rims.
• "Easy Life" sliding center console: The massive armrest with a huge storage space (13 liters in total) can be slid longitudinally. In the forward position, it forms a classic partition between the driver and passenger; when slid back, it frees up floor space and offers its ports to the rear passengers.
• Drawer instead of a glovebox: Instead of the classic flip-down compartment in front of the passenger, Renault introduced the "Easy Life" drawer. This 11.5-liter drawer slides out into the cabin, is cooled, and can be electronically locked.
• One-Touch Folding system: An extremely useful feature for quick interior transformation. All rear seats can be folded completely flat at the touch of a single button, either on the control panel directly in the luggage compartment or via the infotainment touchscreen.
• R-Link 2 vertical infotainment: The interior is dominated by a portrait-oriented touchscreen with a diagonal of up to 8.7 inches. This tablet-style interface offers intuitive control of Multi-Sense driving modes, navigation, and ambient lighting, which changes the cabin atmosphere according to the selected setting.

Citroën Grand C4 SpaceTourer

Pros:

• Three separate and full-sized seats in the second row, each equipped with ISOFIX mounts (ideal for families with three children).
• A huge and easily accessible luggage compartment, offering a class-leading volume of up to 704 liters in a five-seat configuration.
• Exceptional acoustic and suspension comfort, making the car ideal for long highway journeys.
• Panoramic windshield and overall above-average glass area, ensuring great visibility and a bright interior.
• Economical and durable diesel engines from the BlueHDi range, which perfectly match the car's family character.

Cons:

• An older and slower infotainment system, through which even the climate control settings must be impractically operated.
• More pronounced body roll in corners and overall very uncommunicative steering.
• Space in the third row of seats is quite cramped and realistically usable only for smaller children over shorter distances.
• Fewer storage spaces in the front of the interior compared to some direct competitors.

Renault Grand Scénic

Pros:

• Very attractive and dynamic design inspired by SUVs and crossovers, which helps the car age more slowly.
• Highly practical solutions in the cabin, especially the sliding center console and the giant slide-out compartment in front of the passenger (Easy Life drawer).
• Standard 20-inch wheels with a narrow profile surprisingly do not reduce ride comfort and give the car a premium look.
• A more modern infotainment interface and an overall wider and more reliable range of safety-oriented assistance systems.
• Well-tuned EDC dual-clutch automatic transmissions that shift smoothly and logically.

Cons:

• The second row of seats consists of an asymmetrically split bench (60:40 ratio), lacking the flexibility of three independent seats.
• Subjectively and objectively less knee and headroom in the rear seats compared to the Citroën model.
• The atypical 20-inch tire size (195/55 R20) can mean a slightly smaller selection on the market and higher purchase costs when changing tires.
• The luggage compartment has a slightly higher loading lip and a smaller total volume with the seats folded.

Based on long-term data from service reports, manufacturer recalls, and hundreds of reports brought daily by our independent car condition inspection, we have compiled a detailed overview of the most common faults for both of these family MPVs. We focused primarily on models approximately four years old to cover what you will realistically encounter on the used car market.

Citroën Grand C4 SpaceTourer

The family representative from Citroën is valued for its maximum comfort; however, from a reliability perspective, it requires careful engine selection and a check of the onboard electronics.

Engines and Drivetrain

• 1.2 PureTech (Petrol): This three-cylinder engine suffers from a well-known problem with the timing belt, which is immersed in oil. If strict oil change intervals are not followed (or with frequent short city trips), the belt crumbles. The released particles then clog the oil pump pickup, which can lead to fatal engine seizure.
• 1.5 BlueHDi (Diesel): A very popular choice, but watch out for models from the first years of production (roughly until 2022). A typical weakness is the 7mm chain connecting the camshafts, which had a tendency to snap. The PSA Group later replaced it with a stronger 8mm version.
• AdBlue System: In all diesel engines of the BlueHDi family, problems often occur with the AdBlue tank and the integrated pump. The pump cannot be replaced separately, which makes the repair expensive. The fault is indicated by the engine warning light and a limited range warning.

Electronics and Infotainment

• Central Touchscreen: The Grand C4 SpaceTourer relies almost exclusively on touchscreen control, even for the air conditioning. The system is often slow to respond, takes a long time to boot after a cold start, and occasionally freezes completely. In some cases, a software update helps; in others, replacement of the entire display module is necessary.
• Error Messages: Users quite often report false error warnings regarding parking sensors or assistance systems, which usually disappear on their own after restarting.

Chassis

• Rear Axle: The suspension is tuned very softly; however, on heavily used family vehicles, squeaking from the rear axle or faster wear of the bushings appears after years of use.

Summary for Citroën: If you avoid neglected 1.2 PureTech petrol engines and check the history of AdBlue system repairs and timing belt replacements on diesel versions, you will get a reliable and unbeatably comfortable transporter. Most other faults relate more to electronic glitches, which are annoying but do not restrict driving itself.

Renault Grand Scénic

The fourth generation of the Scénic bets on a very attractive design and an innovative approach, which, however, brings several specific characteristics that are good to be prepared for.

Engines and Drivetrain

• 1.3 TCe (Petrol): In roughly four-year-old used cars, you will most often come across this four-cylinder developed in cooperation with Mercedes. It is significantly more reliable than its predecessor (1.2 TCe). The only risk is the formation of carbon deposits in the intake if the car is driven exclusively on short city trips and the engine does not warm up to operating temperature.
• 1.5 Blue dCi (Diesel): An engine with an excellent reputation and enormous durability. Only occasional failures of NOx sensors within the emission system occur.
• EDC Automatic Transmission: Dual-clutch transmissions from Renault can jerk uncomfortably when crawling in traffic jams. It is essential to change the oil in the transmission every 60,000 km; otherwise, premature wear of the clutch plates occurs, which manifests as significant jerking when starting off.

Chassis and Specific Wheels

• Standard 20" tires: All Grand Scénics of this generation left the factory on unusual 20-inch wheels with a narrow profile (195/55 R20). The high weight of the wheels and the specific dimension mean a higher load on chassis components. Steering joints and stabilizer links wear out faster here.
• Tire Price: Owners often complain about the higher purchase price of these atypical tires and their reduced availability in tire shops.

Electronics and Infotainment

• R-Link 2 Multimedia System: Similar to Citroën, the system in Renault is also occasionally unstable. Loss of pairing with a mobile phone via Bluetooth or black screens without an apparent cause can occur. Renault has released a number of software patches over the years, so make sure the latest version is uploaded in the car.
• Aerodynamic Noise: Some owners point out more pronounced wind whistling around the front A-pillars and large rear-view mirrors at highway speeds. This is not a defect as such, but a design feature of the car.

Summary for Renault: From a technical standpoint regarding engines, especially with the modernized 1.3 and the proven 1.5 diesel, it is an above-average reliable car. The biggest bogeyman on the used car market remains neglected maintenance of dual-clutch transmissions and a tired chassis due to the use of large and heavy wheels.

When buying a used car, a thorough inspection is key. Here are some specific points to focus on for these two models, which is why an independent technical inspection of the car is always worth it before the final decision.

When choosing a Citroën Grand C4 SpaceTourer:

• Timing belt condition (1.2 PureTech): Three-cylinder petrol engines use a timing belt bathed in oil, which tends to degrade and crumble if maintenance is neglected. Open the oil filler cap and visually check if the belt is fraying, and strictly demand a documented history of oil changes exactly according to the manufacturer's specifications.
• AdBlue system on BlueHDi engines: In the popular 1.5 and 2.0 BlueHDi diesel engines, the pump in the AdBlue tank often fails, leading to an expensive replacement of the entire module. During the test drive, watch the instrument cluster closely for emission system error messages (UREA light).
• Infotainment and AC functionality: Most car functions, including ventilation and air conditioning controls, are handled exclusively via the central touchscreen. Thoroughly test whether the system responds promptly, does not freeze, and whether the screen is not delaminating, which would prevent you from even such a triviality as lowering the cabin temperature in the future.
• Rear air suspension (on higher trims): If a specific unit is equipped with pneumatic rear axle suspension, listen carefully to whether the compressor runs unnecessarily long or too often. After turning off the engine, check if the rear of the car drops noticeably to the ground, which would indicate an air leak from the bellows.
• EAT8 Automatic Transmission behavior: The modern eight-speed torque converter automatic is generally very reliable but needs clean oil. During the test drive, focus on the smoothness of shifting – the transmission should change gears smoothly and must not jerk even when downshifting as you slowly approach an intersection.

When choosing a Renault Grand Scénic:

• Front axle and bearing wear: All versions of the fourth generation have unusual 20-inch wheels as standard, which take a toll on chassis parts. A thorough physical inspection of the car on a lift should reveal any play in the stabilizer links and bushings. During the drive, listen for humming from the wheels typical of worn bearings.
• EDC dual-clutch transmission smoothness: EDC automatic transmissions can exhibit nervous behavior at higher mileages and with worn clutches. Test the smoothness of starting off without pressing the gas (so-called creeping) on a flat surface and notice any jerking or vibrations when crawling at low speeds.
• R-Link 2 system stability: The vertically oriented R-Link 2 touchscreen can suffer from software errors. Try pairing a phone during the drive, start the navigation, and switch the radio to verify that the system does not respond excessively slowly or restart spontaneously.
• Smooth operation of the 1.3 TCe engine: This four-cylinder gasoline engine from more recent production is significantly more reliable than its predecessor (1.2 TCe), yet you should still focus on its performance. After starting a cold engine, watch for any idling fluctuations, and during acceleration, check that the engine pulls linearly without any "stuttering" or loss of power.
• Condition and prices of tires: Before buying the car, check the tread and production year of the used tires (size 195/55 R20). Because this is an atypical size developed specifically for this model, purchasing a new set can be noticeably more expensive than for common family cars. Also, check the sidewalls for any scuffs from curbs.
