I have a feeling this engine may be a1 989

What is your question?

I am looking for the location of the crankshaft position sensor can anyone help? I have been all over the engine and there are no grey 3 prong plugs,even though the part i have is grey and three prong. It is from BWD Automotive part #css585 crankshaft position sensor for 1990 audi quattro 80
