Washed my 2017 m2 today. Opened the hood to dry the edges and generally check things out - always do this. Found this on the hood. Oil spray/drops. Pretty much directly in line with the oil filter.

So I pull the plastic engine cover off expecting to see oil everywhere. But only find a few drips here and there.

The oil filter housing is clean/dry. And for the most part so are the filter cap area and the plastic engine cover.

Pulled the filter cap off expecting to see a misaligned or damaged o-ring. But it looks fine and was installed properly.

The leak doesn't appear active and must have happened sometime since the last wash - but no clue exactly when.

Any ideas? Is there some possible source - a line or pressure gauge or something - other than the cap and housing in this area?

Hi,

maybe your Chargepipe is cracked at the intake?
The oil can be from the "Kurbelgehaeuse Entlueftung" (i dont know the english word).
