Hi All, new poster here so hope this is in the right section!

I went to see a 2013 335d today. Kinda fell in love with the torque having only ever driven NA petrol engines before but I had one concern - in the engine bay on the left, about half way down there appeared to be some oil staining. I know little about these engines so I have no idea what this is or if it represents a problem. Anyone shed any light from this crappy photo? I couldn't see a source for it and it looked dried/burnt so could be a previous issue/spillage?! Or could be something more serious?

(hoping it uploads okay! If not, I'll host it somewhere)

My 330d has the same issue it was the egr and bmw replaced it under the manufacturer recall scheme

no big deal with that. Its a joiner on the boost pipe that leaks ever so slightly under boost as there is always a small amount of oil in the intercooler and boost pipes.

Spray it on with a degreaser and the powerwash it off and monitor . It will takes months or years to get to that state again

Same with mine. I done the same washed it and now monitoring .. I’ll update in a week or so
