A distinctive French executive hatchback that aimed to bring premium ambitions to the Citroën range. Built on the PF2 platform, the DS5 offered bold styling and a well-appointed interior with above-average material quality for the brand. The 2.0 HDi DW10 diesel is a proven PSA unit found across many models, but the DS5's added electronic complexity and niche market position mean specialist knowledge helps with maintenance.
Proven DW10 diesel engine
Distinctive design, well-equipped
Complex electronics, niche parts
Ride quality firm on poor roads
Buy if: You want a characterful French diesel with strong equipment levels and can maintain the DPF with regular motorway use.
Avoid if: You drive mostly short urban trips (DPF issues) or need a car with cheap, widely available independent garage support.
Expected Annual Maintenance Costs
Common Problems
DPF clogs from short trips, forced regeneration or replacement needed · more· less
The DPF requires sustained highway driving (20+ minutes above 60 km/h) for passive regeneration. Cars driven predominantly in urban traffic develop soot buildup that the system cannot clear. Symptoms include warning lights, reduced power, and limp mode. A forced regeneration at a workshop costs around €150-400. If the DPF is severely clogged or damaged, replacement costs €1,500-2,500 including parts and labor. This is the most common issue reported by DS5 diesel owners, especially on cars with mainly urban use history.
Carbon deposits cause rough running, warning lights, and power loss · more· less
The EGR valve on the DW10 engine accumulates carbon deposits, particularly on cars driven at low speeds or on short trips. Symptoms include rough idle, engine management light, reduced power, and increased exhaust smoke. Cleaning the valve costs around €150-300 at an independent workshop. If the valve is beyond cleaning, replacement runs €500-800 with labor. Typically becomes an issue between 80,000-130,000 km. Regular motorway driving helps prevent buildup.
Oil starvation or carbon buildup causes turbo bearing wear and power loss · more· less
The turbocharger on the DW10CTED4 can fail due to oil starvation (from blocked oil feed pipes) or excessive carbon buildup. Symptoms include blue/white exhaust smoke, a whining noise under boost, loss of power, and check engine light. Early detection via oil line inspection can prevent full turbo failure. A replacement turbo fitted by a specialist costs €1,200-1,800, while Citroën dealer prices reach €2,500-2,800. The oil feed pipe should always be replaced alongside the turbo. Most failures occur above 120,000 km, and regular oil changes with quality oil are the best prevention.
Worn or leaking injectors cause rough running, misfires, and black smoke · more· less
The Bosch piezoelectric injectors on the DW10CTED4 can wear or develop seal leaks over time. Symptoms include rough idle, misfires, excessive black smoke, and a strong diesel smell. A single injector replacement costs approximately €250-400 at an independent specialist. If multiple injectors need replacing, costs climb to €1,000-1,800. Injector seal replacement alone is a cheaper fix at around €150-250. Problems typically appear between 100,000-160,000 km. Using quality diesel fuel and regular fuel system treatment helps extend injector life.
Shift hesitation, harsh engagement, and gearbox warning lights from worn solenoid valves · more· less
The Aisin 6-speed automatic gearbox used in the DS5 is generally reliable but develops valve body and solenoid wear beyond 100,000-130,000 km if transmission fluid has not been changed. Symptoms include jerky shifts, delayed gear engagement, and occasional gearbox warning lights. A gearbox oil change every 60,000 km is recommended (despite Citroën's lifetime fill claim). A fluid change costs around €180-250. If the valve body needs repair, costs are €600-1,500 at a transmission specialist. Full gearbox replacement is rare but costs €2,000-2,500. Manual gearbox equipped DS5s do not have this issue.
Touchscreen freezes, sensor malfunctions, and intermittent warning lights · more· less
The DS5 has a complex electrical architecture with numerous sensors and electronic systems. Common complaints include infotainment screen freezing or restarting during driving, proximity sensor malfunctions, hands-free door handle failures, and intermittent warning lights unrelated to actual mechanical faults. Software updates can resolve some issues (€100-200 at a dealer). Module replacement costs vary: infotainment unit €500-800, sensor replacements €150-400. Battery voltage drops are a frequent root cause, so checking battery condition is important. These issues are annoying but rarely affect drivability.
SCR injector crystallization or NOx sensor failure triggers countdown to engine shutdown · more· less
Post-2015 DS5 models with the BlueHDi engine use an AdBlue (urea injection) system for emissions compliance. The SCR injector can crystallize from short-trip driving, and NOx sensors can become contaminated. When the system faults, the car displays a countdown (typically 2,400 km) after which the engine will not restart. Common fault codes include P20EE and P2BAD. Pump and tank assembly replacement costs €830-1,050. Sensor replacement is cheaper at €300-500. Citroën has offered goodwill coverage for tanks under 5 years and 150,000 km on some models. This issue only affects BlueHDi (2015+) variants, not pre-facelift HDi models.
Solid engine, but complex systems require attentive maintenance
The DW10 2.0 HDi is a well-proven diesel engine used across many PSA models, and high-mileage examples (250,000+ km) exist with proper care. However, the DS5 adds layers of electronic complexity on top of the mechanical base. Most issues are preventable with regular servicing, motorway driving for DPF regeneration, and proactive gearbox fluid changes. Cars with documented service history and predominantly highway use are significantly lower risk.

The DS5 has multiple safety recalls, most critically the Takata airbag stop-drive notice affecting all production years. Contact Citroën or DS Automobiles with the VIN to verify all recalls have been completed before purchase. The Takata recall is ongoing and prioritized by vehicle age.
Warranty Status
Factory warranty (2 years)
Expired on all used DS5s
Rust perforation warranty (12 years)
May still apply to 2014+ models
Extended warranty
Available through Citroën/DS dealers and third-party providers
All DS5 models are well outside their original 2-year factory warranty. The rust perforation warranty of 12 years may still cover later-production cars. Consider third-party warranty options given the car's electrical complexity.
