Peugeot 308 P51

Modern PSA diesel (1.5L BlueHDi) with common-rail, SCR catalyst, and AdBlue. Fuel-efficient and torquey, but the camshaft chain (only 7 mm wide) is the biggest weak point — Stellantis extended the warranty to 10 years/240,000 km. Always check whether the 8 mm chain update has been performed. The AdBlue system and DPF are prone to issues with short-trip driving. The high-pressure fuel pump can seize from fuel contamination.

• !! Premature timing chain wear — subject to recall from 80,000 km

  The only 7 mm wide timing chain stretches prematurely and can snap. Oil dilution from short-trip use accelerates the problem. Stellantis has initiated a mega recall covering 141,700 vehicles in Germany.

  Symptoms: Rattling or clattering on cold start, engine management light, rough engine running, in the worst case sudden engine shutdown from chain snap while driving

• !! High-pressure pump seizes from 40,000 km

  The Bosch high-pressure pump on the DV5 can seize, particularly on vehicles with fewer than 50,000 km. Metal swarf enters the fuel system and requires replacement of the entire injection system.

  Symptoms: Engine no longer starts or stalls while driving, engine management light, metallic noise from engine bay, power loss shortly before total failure

• !! Timing chain recall — warranty extension

  Stellantis has extended the warranty to 10 years / 240,000 km (since July 2025). A software update increases oil pressure and a special oil change is performed. Chain replacement free of charge if required.

  Symptoms: Affected vehicles receive a recall notification. Workshop performs diagnosis, checks chain stretch via camshaft/crankshaft sensor comparison.

+ 5 more engine weaknesses + vehicle weaknesses

Further developed PureTech 130 (96 kW) with Euro 6d and gasoline particulate filter (GPF). Later production years have a timing chain instead of the problematic wet belt — always verify which variant is installed before purchase. The engine uses solid tappets without hydraulic lash adjustment, requiring manual valve clearance checks every 80,000 km. Piston ring coking on short trips is a known issue. Fundamentally much more reliable than the predecessor EB2 generation.

• !! Oil consumption from coked piston rings from 60,000 km

  The 1.2 PureTech tends towards increased oil consumption from coked oil control rings. At high operating temperatures the rings coke up and allow oil into the combustion chamber. Up to 1 litre per 1,000 km is possible.

  Symptoms: Dropping oil level between services, bluish exhaust smoke on cold start, oil consumption warning on display

• !! Wet belt debris blocks oil strainer (older EB2 variants) from 80,000 km

  On older PureTech variants with a wet belt, rubber debris from the timing belt can block the oil pump strainer and cause oil pressure loss. The EB2ADTS has a timing chain, but verify risk on transitional models.

  Symptoms: Oil pressure warning, engine noise, sudden power loss, engine damage if driving continues

• !! Weak crankshaft thrust washers from 100,000 km

  The crankshaft thrust washers (half-rings) cannot withstand the loads and cause axial play. Once play exceeds 0.5 mm there is a risk of the chain jumping off its sprockets and valves hitting pistons.

  Symptoms: Knocking noises from the engine block, noticeable play at the crankshaft, rough engine running

+ 3 more engine weaknesses + vehicle weaknesses

1.2-liter three-cylinder turbo with 48V mild hybrid system and timing chain (NOT a wet belt like the predecessor EB2DTS). 21 kW electric motor integrated into the e-DCS6 dual-clutch gearbox. Available from 2024 in the 208 P21, 2008 P24, and 308 P51 as the MHEV variant. More reliable than the predecessor thanks to the elimination of the wet belt design, though still too new for comprehensive long-term data.

• !! MCU calibration fault — loss of drive

  A miscalibrated motor control unit (MCU) incorrectly detects an internal insulation fault and opens the clutch as a result — unexpected loss of drive while moving is possible.

• !! e-DCT6 shuddering and protective shutdown (early production) from 10,000 km

  The new e-DCT6 dual-clutch gearbox shows occasional shuddering at low speeds, shift hesitation or protective shutdowns on early production vehicles — usually caused by immature software calibration.

  Symptoms: Shuddering when pulling away and at low speed, shift hesitation, occasional gearbox fault messages, warning lights (ESP, ADAS)

Plug-in hybrid powertrain with a 1.6-liter turbo petrol engine (132 kW) and electric motor (81 kW). 12.4 kWh battery providing approximately 50-60 km of electric range. EAT8 automatic gearbox comes standard. The combustion engine is based on the EP6 family with well-known timing chain issues. The interplay between combustion engine and electric motor is complex — software updates are frequent. The high-voltage battery and power electronics add further potential failure points.

• !! On-board charger and traction battery series defect from 42,000 km

  On the 508/3008 PHEV OBC failures and traction battery faults (fault code P12F03) are documented. Affected vehicles at 40,000–44,000 km. Spare parts lead times are often several months. Costs up to 6,100 € net for a new battery.

  An internal traction battery fault causes fault code P1A4B25. The electric drive runs at severely reduced power and regeneration drops out. PSA requires a complete battery replacement (no cell-level repair possible). Cost 6,100 € net.

More powerful electric motor (157 kW) on the e-CMP platform for the 308 class. 54 kWh battery with up to 400 km WLTP range. Technically a further development of the EM-100/115 at a higher power level. Shares the CMP-typical weaknesses (OBC, 12V battery, heat pump) but benefits from a later production start and more mature software. Still limited long-term field experience available at this point.

• !! BMS software: drive failure while driving from 15,000 km

  Faulty BMS software configuration causes sudden drive loss while driving. Recall MDY for 2022 model year vehicles (e-208, e-2008, e-Partner, e-Rifter).
