DPF clogging and oil dilution on diesels
SeriousExhaust & EmissionsThe 1.3 and 1.6 MultiJet diesels are fitted with a Diesel Particulate Filter that needs regular motorway driving to regenerate. Short urban trips cause the DPF to clog, triggering warning lights and limp mode. If regeneration is repeatedly interrupted, fuel contaminates the engine oil, causing the level to rise and potentially damaging the engine.
Most affected: 1.3 MultiJet, 1.6 MultiJet
Typical symptoms
- •DPF warning light
- •Limp mode
- •Engine oil level rising
- •Loss of power
- •Cooling fan running after shutdown
What to inspect before you buy
- ✓Ask about the car's usual journey pattern
- ✓Check the oil level for signs of diesel dilution
- ✓Look for invoices for DPF cleaning or forced regeneration
