Peugeot 5008 1.6 PureTech 180 Mk2

The 1.6 PureTech 180 uses the EP6FADTX engine with a timing chain (not a wet belt like the 1.2 PureTech). The chain can stretch as early as 80,000-120,000 km, particularly with aggressive start-stop operation and extended oil change intervals. The plastic chain guide is thin and wears relatively quickly, causing chain rattle on cold starts. If ignored, the chain can skip teeth and cause valve-piston contact, destroying the engine. Early warning signs include a rattling or clattering noise for a few seconds after cold start. Replacement of the chain, tensioner, guides, and VVT gears costs approximately 1,200-1,800 euros at an independent specialist or 2,000-3,000 euros at a Peugeot dealer. Peugeot revised the chain tensioner on later production cars (2019+). Regular oil changes every 10,000 km with the correct 5W-30 specification are essential for chain longevity. Unlike the 1.2 PureTech, the 1.6 is not covered by the Stellantis extended warranty programme.

The direct-injection EP6 engine is prone to carbon deposits building up on the piston oil control rings, causing them to stick and allowing oil to pass into the combustion chamber. Some owners report consuming 0.5-1.0 litre per 1,000 km. Peugeot considers up to 0.5 litres per 1,000 km as acceptable, but many owners find this excessive. Short-trip driving makes it worse because the engine never fully reaches operating temperature. Regular spirited driving and occasionally using higher RPMs can help prevent carbon buildup. If rings are severely seized, the engine requires a top-end rebuild (2,000-4,000 euros) or in extreme cases complete engine replacement. Using the correct oil specification and changing it at no more than 10,000 km intervals reduces risk significantly. Monitor the dipstick between services and keep a litre of oil in the boot.

Because the 1.6 PureTech 180 uses direct injection, fuel is sprayed directly into the cylinder rather than across the intake valves. Oil vapours from the crankcase ventilation system deposit on the valves and harden over time. This gradually reduces airflow, causing rough idling, misfires, and progressive power loss. Symptoms typically appear between 60,000 and 100,000 km. Cleaning via walnut blasting or chemical treatment costs 300-600 euros at a specialist. Regular motorway driving at higher RPMs helps slow the buildup. Predominantly urban driving accelerates it significantly. The heavier 5008 driven frequently in city traffic can develop symptoms earlier due to lower average engine temperatures.

The EP6 engine uses a camshaft-driven high pressure fuel pump that can develop internal wear. Early symptoms include a slight hesitation or misfire at low engine speeds. In severe cases, the engine loses power completely and stalls, particularly during highway driving. A genuine Peugeot HPFP costs approximately 500-800 euros, while quality aftermarket units are 300-500 euros. Labour takes 3-5 hours due to accessibility, adding 400-600 euros. The total repair typically runs 800-1,800 euros depending on parts choice and workshop. Failure usually occurs after 80,000-100,000 km. Regular fuel filter replacement helps protect the pump.

The turbocharger on the EP6 engine can develop issues after 80,000+ km. The exhaust housing may develop hairline cracks around 60,000-80,000 km, and the wastegate actuator may stick, causing limp mode and loss of boost. A whistling noise during acceleration or visible blue/grey exhaust smoke indicates turbo seal failure. The actuator alone can sometimes be repaired for 400-600 euros, but if the turbo cartridge is damaged, a replacement unit costs 1,200-2,500 euros including labour. Regular oil changes are critical as the turbo relies on engine oil for lubrication and cooling. Allow the engine to idle for 30 seconds before switching off after hard driving to prevent oil coking in the turbo bearings.

A widely reported issue on 5008 Mk2 models equipped with the panoramic roof, shared with the 3008 on the same platform. Water enters through gaps where the side rails meet the front rail. Symptoms include dripping from the overhead light console or water running from behind the rearview mirror after heavy rain. Multiple forum threads describe owners returning three to four times without permanent resolution. Repair involves removing the headlining, clearing drain tubes, and resealing with mastic. Specialist quotes range from 300-800 euros. Peugeot has offered goodwill contributions of up to 75% on some repairs. Cars without panoramic roof are unaffected.

The Peugeot i-Cockpit system on pre-facelift cars (2018-2019) is known for software instability. Common complaints include the touchscreen freezing or going black, Bluetooth connectivity dropping, and phantom warning lights appearing. In many cases the root cause is a failing 12V battery, as the i-Cockpit electronics are sensitive to voltage drops. A new battery costs 80-150 euros fitted. A soft reset (holding the power button for 10-20 seconds with ignition off) often resolves temporary glitches. Peugeot released several software updates that significantly improved stability. Post-2020 facelift models are notably better. In rare cases the infotainment unit itself fails and requires replacement (300-500 euros for a refurbished unit). Replacing the 12V battery every 4-5 years helps prevent phantom fault codes.

Some owners report the electric parking brake failing to release when pulling away, or showing a parking brake fault warning. The issue is usually traced to the electric motor in one of the rear brake calipers, the parking brake switch, or a faulty wheel speed sensor. A new caliper with integrated motor costs approximately 250-350 euros plus fitting. The parking brake switch or wiring repair is typically 100-200 euros. Diagnostic testing (80-100 euros) is recommended before replacing parts to identify the exact cause.
