So we found out after an wild damage that my car lost some oil. We dont know yet what it is.
I add some pics , maybe anyone here know what it could be.
Never lost oil on many miles and it isnt from the crash.
no messages onboard ect. motor : 306DT

In what area was the car hit? This looks like some plastic part has a hairline crack in it

Probably from the turbo byepass

It only takes traces of condensed oil mist from the crankcase breather system to ooze out of O ring joints on the pressurised side of the intake then attract dust and make a lot of mess from not much oil. At the intake at the top front of the 3d is one such source. There is a big O ring there behind the big circlip that oozes. Mine does the same. Dealer offered to change the O ring for a couple of hundred but a bit of engine cleaner degreaser now and again does the same thing. There's no boost leak. Not pretty but probably harmless if no engine oil is lost.
