Frequent Problems in the Peugeot 308
If you have the check engine light on in your Peugeot 308, it could be due to several common faults depending on whether it's a petrol engine (TSI, EcoBoost, VTi...) or diesel (TDI, TDCi, BlueHDi...):
- Problems with the EGR valve and the particulate filter (DPF) in diesel engines, causing power loss.
- Misfires (coils or spark plugs), causing jerking and the P0300 code.
- Dirty or faulty oxygen sensors (Lambda probe), which increase fuel consumption.
