Diesel Oil Dilution and DPF Clogging
SeriousEngineIncomplete DPF regenerations lead to fuel entering the oil sump. If not caught, this can lead to engine "runaway" or bearing failure.
Most affected: 2.0 VCDi diesel
Typical symptoms
- •Rising oil level on dipstick
- •DPF warning light
- •Frequent "active" regenerations (high idle)
What to inspect before you buy
- ✓Check the oil level; it should not be above the "Max" mark
- ✓Ask about the car's typical usage (motorway vs town)
