DPF Clogging (Diesel Models)
SeriousEngineThe diesel particulate filter clogs quickly if the car is not driven on the motorway regularly. Interrupted DPF regenerations can cause diesel to leak into the oil sump, thinning the lubricant and potentially damaging the engine.
Most affected: 1.6 DDiS, 1.6 DDiS AllGrip
Typical symptoms
- •DPF warning light on dash
- •Oil level rising above max on dipstick
- •Limp mode or reduced power
- •Strong smell of diesel at idle
What to inspect before you buy
- ✓Check the oil level for signs of rising above the max mark
- ✓Ask about the previous owner's driving pattern
- ✓Scan for DPF-related fault codes
