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.
