Peugeot 2008 Mk2 1.2 PureTech

The 1.2 PureTech EB2 uses a timing belt running submerged in engine oil. Over time, fuel dilution of the oil creates an abrasive mixture that accelerates belt wear. Belt fragments can block oil galleries, VVT solenoids, the oil pickup strainer, and the brake vacuum pump. The Mk2 (2019+) uses an improved Gen3 belt material, which is more durable than the pre-2017 design but remains fundamentally the same wet belt concept. Stellantis reduced the replacement interval to 100,000 km or 6 years. Belt replacement at an independent specialist costs €800-1,000 (parts approximately €225, labor 5-7 hours due to the complexity of this specific engine). If belt debris has already contaminated the VVT system or oil pump, costs escalate to €1,500-2,500. If the belt snaps, the engine is destroyed (interference design) and replacement runs €3,000-5,000. From 2023, Stellantis switched to a timing chain on updated PureTech variants, acknowledging the design weakness. The Stellantis compensation programme covers 100% of repair costs for engines under 10 years or 180,000 km with documented service history.

Many PureTech owners report oil consumption of 0.5-1 litre per 1,000 km, well above the manufacturer's stated maximum of 0.25 litres per 1,000 km. The root cause is carbon buildup on the piston oil control rings, which prevents them from scraping oil effectively. Short trips and gentle driving exacerbate the problem as the engine rarely reaches optimal operating temperature. High oil consumption also accelerates timing belt degradation since the belt runs in oil. In mild cases, more frequent oil changes (every 7,500 km instead of the standard 20,000 km interval) and regular motorway driving can manage it at the cost of extra oil top-ups (€50-100 per year). Severe cases require piston ring cleaning or replacement at €1,500-2,500. The Stellantis compensation programme may cover these repairs for qualifying vehicles.

The turbocharged 1.2 PureTech uses a cam-driven high pressure fuel pump for direct injection. These pumps can fail prematurely, typically between 60,000-100,000 km. Symptoms include loss of power, rough running, difficulty starting, and the P0087 low fuel pressure fault code. A genuine Peugeot replacement pump costs €500-700, with 3-5 hours labor. Aftermarket alternatives are available for €300-400. Peugeot has offered goodwill contributions for cars under 6 years or 100,000 km. The naturally aspirated PureTech 75 (port injection only) does not have an HPFP and is not affected by this issue.

The EB2 engine uses an electric water pump integrated with the thermostat housing. The pump shaft seal can corrode, and the plastic thermostat housing develops micro-cracks from thermal cycling. Symptoms include low coolant warnings, poor cabin heating, or visible coolant pooling underneath the car. The integrated design means the entire unit typically needs replacing. Parts cost €200-350 plus 3-4 hours labor. If overheating occurs before the leak is detected, head gasket damage can push costs significantly higher. Peugeot updated the thermostat housing design in later production runs. Checking coolant level regularly is advisable on all PureTech engines.

The Positive Crankcase Ventilation valve is integrated into the rocker cover and cannot be replaced separately. When the PCV membrane fails, symptoms include a whistling or hissing sound from the engine at idle, rough running, misfires, increased oil consumption, and poor fuel economy. Since Peugeot does not sell the PCV membrane as a separate part, the entire rocker cover assembly must be replaced. Parts cost €180-250 plus 2-3 hours labor. This issue typically appears between 60,000 and 120,000 km. Aftermarket PCV membrane repair kits exist but require careful installation.

The Euro 6d PureTech engine includes a gasoline particulate filter (GPF) that requires periodic high-temperature regeneration. If the car is driven exclusively on short urban trips, the GPF never reaches the 600-650 degrees Celsius needed for passive regeneration. This causes soot buildup, triggering engine warning lights and eventually restricting power. Active regeneration (ECU-initiated at 450 degrees Celsius) can also fail if journeys are too short. Regular motorway runs of 20-30 minutes at higher speeds help keep the GPF clean. Professional GPF cleaning costs €300-500, while full replacement can reach €1,000-1,500. This is primarily a concern for drivers who rarely leave urban areas.

The 10-inch infotainment touchscreen can intermittently fail to turn on, display a black screen, or freeze on the startup logo. This is a firmware issue that Peugeot has acknowledged. In many cases, a software update at a Peugeot dealer resolves the problem. If the screen hardware has failed, replacement costs €500-800. The issue is annoying rather than safety-critical, as the digital instrument cluster continues to function independently. Disconnecting and reconnecting the battery can provide a temporary fix.
