Peugeot 5008 2.0 BlueHDi Mk2

The AdBlue (urea) system on the 2.0 BlueHDi is one of the most commonly reported failure points. The pump, injector, and NOx sensors can all fail independently. Symptoms include engine fault warnings, reduced power, and countdown warnings threatening to prevent restart. The NOx sensor costs approximately €350-700 to replace, the AdBlue pump €600-1,200, and the injector €150-400. A recall affects cars built June 2020 to November 2022 for urea injector blockage. Even outside the recall, these components degrade over time, particularly with infrequent use or crystallization from poor-quality AdBlue fluid. Failures typically appear between 60,000-120,000 km.

The DPF requires sustained motorway driving to reach regeneration temperatures (approximately 550°C for passive regeneration). Cars used predominantly for short urban trips accumulate soot faster than the system can burn off. Symptoms include increased fuel consumption, exhaust smoke, reduced performance, and eventually a DPF warning light. Forced regeneration at a workshop costs €100-200, professional cleaning €300-500, and full DPF replacement €800-1,500 for aftermarket or up to €2,000 for OEM. Prevention is straightforward: regular 30+ minute motorway drives allow the system to self-clean.

The Aisin EAT8 gearbox is generally reliable but develops shift quality issues over time, particularly if the transmission fluid is not changed. Peugeot officially claims the fluid is lifetime-fill, but specialists recommend changes every 60,000-80,000 km (approximately €300 at an independent garage). Without fluid changes, valve body deposits build up causing sluggish downshifts, a pronounced thud when selecting lower gears during deceleration, and gear hunting on gradients. Mild cases resolve with a fluid change and software update. Severe cases may require valve body repair (€1,500-2,500). Manual gearbox versions do not have this issue.

The EGR valve on the DW10 engine accumulates carbon deposits over time, particularly with urban driving patterns. Symptoms include reduced power, rough idle, increased fuel consumption, and engine warning lights. The EGR module on these engines comes as a complete assembly with integrated heat exchanger, making partial repair difficult. Cleaning may provide temporary relief but replacement is often necessary. Parts cost approximately €250-450, with labor adding €150-300 due to accessibility. Typically becomes an issue between 80,000-140,000 km depending on driving patterns.

The electric tailgate experiences problems in two waves: early failures around 15,000 km from software errors (typically resolved via update), and later mechanical failures around 80,000-100,000 km from worn hall sensors or damaged wiring near the hinge area. The wiring harness flexes every time the tailgate opens and closes, eventually causing conductor fatigue. Simple wiring repairs cost around €100, sensor replacement approximately €200-400, and full strut or motor replacement up to €600. Not a safety concern but an annoying quality-of-life issue.

The i-Cockpit infotainment system can freeze, display a black screen, or reboot spontaneously. In most cases, a system reset (holding the power button for 10-20 seconds) resolves the issue temporarily, and a dealer software update provides a more permanent fix (€50-150 for diagnosis and update). In rare cases, the display unit itself fails and requires hardware replacement (€500-800). The digital instrument cluster TFT screen can also develop faults, though this is less common. Software updates have improved stability significantly on later production cars.
