- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature.

When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly

Possible Causes :
- Some aftermarket accessories and performance modifications
- A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area.
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
