Engines: 1.2 PureTech (Petrol)

Oil-bath timing belt degradationTiming / lubrication

Engine / equipment: 1.0 / 1.2 PureTech (EB2) in the Peugeot 208/2008/308/3008/5008, Citroën C3/C4/C5 Aircross, DS 3, Opel Corsa/Crossland/Grandland
Period mentioned: 2012 – approx. 2022
Symptoms: Oil pressure warning, hard brake pedal or reduced assistance, oil consumption, blue smoke, squeal at the front of the engine, turbo whistles or loses power.
Possible cause described: The timing belt runs in oil and degrades (especially with short trips and fuel dilution). Debris clogs the oil pump strainer, the brake vacuum pump filter, the turbo oil feed and the variable valve timing solenoids. Stellantis announced compensation for affected owners in 2025.
Check for the garage: Measure the belt through the oil filler opening with the manufacturer's tool. Confirm whether the vacuum pump campaign was done.
Cost cited in the source: Vacuum pump: €500–800; belt with oil system cleaning: considerably moreA rough figure from the original database, not an up-to-date quote.

Applies if: Only if fitted with the automatic gearbox described in the record.

EAT6/EAT8 jerking and torque converterAutomatic gearbox

Engine / equipment: Aisin EAT6 and EAT8 automatic gearboxes (308, 3008, 5008, 508, 2008, C4 Picasso, C5 Aircross, C4, DS 7, Grandland…)
Period mentioned: 2013–2026
Symptoms: Hesitation or a jolt between 1st and 2nd, torque converter shudder in traffic, harsh or delayed shifts and a gearbox fault warning, especially on 2017–2019 3008s.
Possible cause described: Torque converter wear or drift, valve deposits from degraded oil and software faults. Peugeot treats the oil as lifetime, but dirty or low oil causes harsh shifts.
Check for the garage: Check oil level and condition, update the gearbox software at the dealer and, after an oil change, record it with DiagBox and reset the adaptations.
Cost cited in the source: Oil change and update: the most common fix; torque converter or valve body: specialist garage repairA rough figure from the original database, not an up-to-date quote.

Rear cross-member squeak on the Peugeot 308 IISuspension and steering

Engine / equipment: Peugeot 308 II built up to June 2016
Period mentioned: 2013–2016
Symptoms: Squeak from the rear axle on uneven roads or when the car's weight shifts in bends; it gets worse with mileage. A knock from the rear can also come from the silencer's rubber mount (cars built up to 9/10/2016).
Possible cause described: Rubbing between the pressed lower part and the rounded upper part of the rear cross-member. It affects cars built up to 10/12/2015 with a 25,000 Nm/rad anti-roll bar (the cross-member is replaced) and, according to a January 2017 note, those with a 30,000 Nm/rad bar built up to 20/6/2016 (some parts are replaced).
Check for the garage: Tell the garage when it squeaks (bumps, bends) and ask about the technical note on the cross-member; also have the silencer's rubber mount checked.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

1.6 THP chain and tensionerTiming system

Engine / equipment: 1.6 THP / VTi (EP6, PSA-BMW “Prince” engine): Peugeot 207/208/308/3008/5008/508/RCZ, Citroën C4/C5/C4 Picasso, DS 3/4/5
Period mentioned: Approx. 2007–2018
Symptoms: Metallic rattle for several seconds after a cold start; engine light for timing deviation.
Possible cause described: The chain stretches and the tensioner is soft. Later units have a revised chain and tensioner, which reduce but do not eliminate the fault.
Check for the garage: Listen to a cold start and check whether the chain was replaced with the revised parts.
Cost cited in the source: Approx. €800–1,500 (converted from dollars)A rough figure from the original database, not an up-to-date quote.

Turbo oil starvation from injector carbonTurbo / injection

Engine / equipment: 1.6 HDi DV6 (Peugeot 207/308/3008/Partner, Citroën C3/C4/Berlingo; same engine as the Ford 1.6 TDCi)
Period mentioned: Approx. 2004–2015
Symptoms: Loud turbo whistle, power loss, blue or black smoke, oil that gets dirty very quickly. Before the failure, often a puffing or ticking from the cylinder head and an exhaust smell from an injector.
Possible cause described: The injector clamp bolts work loose, the gas leak forms carbon that gets into the oil and clogs the mesh filter in the banjo bolt feeding the turbo. The turbo is starved of oil. Replacing only the turbo does not fix it.
Check for the garage: Check injector bolt torque and carbon at their base, the turbo banjo bolt and the sump strainer.
Cost cited in the source: Turbo + full oil system cleaning: approx. €900–2,000 (estimate)A rough figure from the original database, not an up-to-date quote.

AdBlue system failure (start countdown)Exhaust and emissions (AdBlue)

Engine / equipment: 1.5 / 1.6 / 2.0 BlueHDi with AdBlue (Peugeot, Citroën, DS, Opel)
Period mentioned: Approx. 2014 onwards
Symptoms: Emission system fault message and a “starting impossible in X km” countdown, AdBlue/UREA warning and engine light.
Possible cause described: Failure of the AdBlue tank pump module (circuit board, pressure sensor or heater) or of the AdBlue injector. The engine does not stop while driving, but once the countdown reaches zero it will not restart.
Check for the garage: Diagnose with Diagbox or equivalent: AdBlue pressure, flow test and tank temperature.
Cost cited in the source: Complete module or tank: approx. €600–1,500 (estimate)A rough figure from the original database, not an up-to-date quote.

1.5 BlueHDi camshaft chainTiming system

Engine / equipment: 1.5 BlueHDi (DV5): Peugeot 208/2008/308/3008/5008/508/Rifter, Citroën C3/C4/C5 Aircross/Berlingo, Opel, DS, Fiat
Period mentioned: 2017–2023
Symptoms: Rattle from the top of the engine, loss of power; in severe cases the chain breaks and the engine fails.
Possible cause described: The 7 mm chain linking the two camshafts wears prematurely, influenced by soot in the oil. Stellantis replaced it with an 8 mm chain in 2023 and opened an inspection campaign.
Check for the garage: Ask the dealer whether the car is in the campaign (free inspection and replacement if needed) and whether the 8 mm chain is fitted.
Cost cited in the source: €700–1,400 for the chain; €4,000–7,000 if it breaksA rough figure from the original database, not an up-to-date quote.
