The oil is my BMW 3 Series is reading high - should I have it checked out?
The oil appears to be reading high in my diesel E90 BMW 3 Series, both via the dashboard indicator and also by manually checking (after driving approximately seven miles and leaving five minutes to cool). Should I have it checked out?
Yes. Might be because active regeneration of the DPF is not occurring or is being interrupted.
