I am new to the world of diesel. Compared to a BMW 520d for example, the engine is quite rumbly. Is that the nature of the engine? I do like it, but is that how it is supposed to sound? How would I know if my D5 is underperforming. Any tests I can run using the OBDII reader for example, as opposed to a compression test?
I received my car back and a litre of oil was removed. However the engine code still persists, and the car still shows overfilled oil.
Thanks.
