So my car needs a service (E60 520D Msport). Booked in for next week.
Because of this i have been watching oil etc like a hawk. This week i noticed oil level ok change to yellow and oil level too high.

I plugged in an odb reader today and got a P14A3 power train fault code back.
So looks like the DPF needs cleaning. I booked in for this tomorrow.

Reading up etc it looks like a clogged DPF can cause diesel to end up in with the oil obviously raising the level. The more Diesel that gets in obviously the more disastrous it will
be as it will blow the engine.

Has anyone else seen this? Am i on the right track?
Im getting my DPF removed, cleaned and replaced tomorrow then serviced straight after.
I should also see a shift in performance as the filter must have been clogged for some time now?
