housemaster said:My E46 M3's of which I have owned 2 in the past were both wet sump and it was very clear in the manual that over filling them with oil was 'likely' to cause engine damage. On 4 separate occasions I took my car back to the dealers after servicing to get them to remove excess oil. Eventually they learned to stop over filling them, and I was astonished to see their total lack of understanding of the problems of over filling M3's even though it was stated by BMW that it was no no. My wifes Golf Mk5 Golf GTI also states clearly that you should never over fill the engine oil as this may cause damage to the engine.
My 330d is always overfilled by dealers too. Very annoying
