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.

- 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.
