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

- 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.
