Peugeot 3008 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 complete engine replacement (€4,000-6,000). A second batch of supposedly upgraded chains from late 2019 was also found to be underspec, triggering a formal recall across over 1 million Stellantis vehicles. Stellantis extended coverage to 10 years / 150,000 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. Retroactive reimbursement is available for repairs paid between January 2023 and June 2025 via stellantis-support.com. This is the single most important check before buying any 1.5 BlueHDi.

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 2017-2018 builds are most affected. Symptoms include AdBlue warning light despite adequate fluid level, and eventually the engine refuses to start. 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). One owner on Peugeot forums documented the problem recurring 7 times in a single year. 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. This 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, indicating the system is struggling. 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 — this is subject to a recall. Prevention: drive at least 20-30 minutes at highway speed once per week.

A widely reported issue on 3008s equipped with the optional panoramic roof. Water enters through gaps where the side rails meet the front rail — a construction/seal design issue rather than wear. Symptoms include dripping from the overhead light console or water running down from behind the rearview mirror after heavy rain. Multiple forum threads describe owners returning for this issue 3-4 times without permanent resolution. Repair involves removing the headlining, clearing drain tubes, and resealing with mastic. Book time is 1.5-2.5 hours. Removing the panoramic glass risks cracking it. Specialist quotes range from €300-800 including headlining work. 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 €200-400. Full replacement runs €400-600 including labour. 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, oxidised connector pins on the control module, or wiring harness issues. A battery reset sometimes clears transient faults. The handbrake switch itself can be replaced with an aftermarket unit for €50-100. The full control module replacement costs €300-500 at a dealer, though used spares from breakers run €100-150.

Multiple owners report cascading electrical faults: varying fault codes, spanner icons appearing and disappearing, 'Engine fault' and 'Gearbox fault' messages. 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 (via dealer) have resolved several recurring glitches. Early 2017-2018 builds had the most software issues; later production runs are notably more stable. Replace the 12V battery every 4-5 years as preventive maintenance.
