Peugeot 5008 Mk2 1.5 BlueHDi

The 1.5 BlueHDi DV5 engine produced between October 2017 and January 2023 uses a 7mm timing chain that wears prematurely. Soot-laden oil accelerates chain and tensioner degradation. Early warning: rattling for 1-30 seconds on cold start. If the chain snaps, pistons and valves collide, typically requiring engine replacement (€4,000-6,000). A second batch of supposedly upgraded chains from late 2019 was also found to be underspec, triggering a recall affecting over 1 million Stellantis vehicles. Stellantis extended coverage to 10 years / 240,000 km from first registration (announced mid-2025), covering 100% of parts and labour. Conditions: maintenance must follow manufacturer intervals using approved oil (Total Quartz INEO RCP 5W30). Preventive chain replacement with the upgraded 8mm chain costs €2,000-3,000 at independent shops. Retroactive reimbursement is available for repairs paid between January 2023 and June 2025 via stellantis-support.com. Cars built after January 2023 received the improved 8mm chain from factory.

The second most common issue on the 1.5 BlueHDi. The AdBlue injector blocks from urea crystallisation, while the pump (built into the tank) fails when its circuit board is contaminated by AdBlue fluid leaking into the sealed electronics zone. Early 2017-2019 builds are most affected. Symptoms include AdBlue warning light despite adequate fluid level, and eventually the engine refuses to start after approximately 1,000 km of warnings. A software reset fixes some false alarms (€100-150). NOx sensor replacement costs approximately €500-700. Full AdBlue tank and injector replacement runs €1,500-2,500. Peugeot has offered goodwill repairs on well-serviced cars (up to 75% coverage reported on forums). Only refill AdBlue when the car prompts you, using approximately 10 litres at a time.

The DPF requires periodic high-temperature regeneration to burn off accumulated soot, which only happens during sustained driving at motorway speeds (60+ km/h for 15+ minutes). Cars used predominantly for short urban trips saturate the filter. Some owners report regeneration cycles occurring every 40-70 km instead of the normal 150-500 km interval. The DPF additive tank requires topping up around 110,000 km — when empty, assisted regeneration cannot occur and the filter blocks. Professional ultrasonic cleaning costs €250-400. If the filter is beyond cleaning, replacement runs €900-1,500. Cars built between January and May 2018 had a plastic exhaust component that could damage the DPF, subject to a recall. Prevention: drive at least 20-30 minutes at highway speed once per week.

A widely reported issue on 5008s equipped with the optional panoramic roof. Water enters through gaps where the side rails meet the front rail, a construction issue rather than wear. Symptoms include dripping from the overhead light console or water running down behind the rearview mirror after heavy rain. Multiple forum threads describe owners returning 3-4 times without permanent resolution. Repair involves removing the headlining, clearing drain tubes, and resealing with mastic. Labour typically 1.5-2.5 hours. Some owners have successfully fixed it with butyl mastic tape sealing the gap (a 15-minute DIY fix). Peugeot has offered 75% goodwill contributions on some repairs. A Peugeot TSB exists for this issue. Cars without panoramic roof are unaffected.

The EGR valve recirculates exhaust gases and accumulates carbon deposits, especially with short-distance driving. Symptoms include sluggish throttle response, increased fuel consumption, and check engine light. Professional removal and cleaning costs €120-250. Full EGR valve replacement including gasket and labour runs €400-600. Cleaning is recommended every 50,000 km as preventive maintenance. Regular longer drives at higher RPM help keep the valve clean.

The electronic parking brake can malfunction in several ways: failing to auto-release when driving off, throwing intermittent fault warnings (especially after the car sits for several hours), or becoming stuck. Common causes include actuator motor seizure (replacement around €500), oxidised connector pins, or rusting between rear pads and discs after periods of inactivity. A battery reset sometimes clears transient faults. The handbrake switch itself costs €50-100 to replace. Keeping the 12V battery in good condition reduces false fault alerts.

Multiple owners report cascading electrical faults: varying fault codes, spanner icons appearing and disappearing, 'Engine fault' and 'Gearbox fault' messages. The i-Cockpit infotainment screen randomly restarts or freezes, and Bluetooth/CarPlay connectivity drops. In many cases the root cause is a failing 12V battery — the car's complex electronics are sensitive to voltage drops. A new battery costs €80-150 fitted. Software updates from Peugeot have resolved several recurring glitches. Early 2017-2018 builds had the most software issues; later production runs are more stable. Replace the 12V battery every 4-5 years as preventive maintenance.

In cold climates (below -5C), condensed water collects in the turbo intercooler during longer drives. If the car sits overnight in freezing conditions, the water freezes and blocks airflow, triggering an engine fault and limp mode on the next drive. The issue clears once the car warms up, but it can recur every few days in winter. Peugeot dealers acknowledge the problem but have no official fix. Some owners have resolved it by adding an extra draught cover to restrict cold airflow through the intercooler. Primarily affects cars in Northern Europe. The repair cost is minimal (diagnostic fee plus any deflector modification), but the inconvenience is significant.
