IDENTIFYING PART - AUDI A4 B5 1.9TDI
hi, i would like to know what is this part in the image.
it looks like a sensor of some kind, behind the engine of my Audi A4 B5 1.9TDi.
Tried putting this part back in place but it is not staying.
Closely to it there is two more of the same thing, but they are okay in positions.
