I have 2002 520i sport, it seem to be using a bit of oil. I had a yellow oil can come onto today when i stopped the car, when i dipped it it was a little low. Car has 130 k on it. Im going to reset the milage on the trip computer and see how long it takes for it to get lowish again.

Ive heard the ccv? (<--- think thats what It is called) Can cause this issue if it gets clogged or blocked. Cant send the oil so just dumps it back in the head hence oil usage. Is this located at the front near the oil cap? As i took this pipe off and it cracked on the flexi ( have a temp repair done) but their looked to be a good bit of crap built up inside it.
