I have my friends 98 Audi A4. It seems like there is no compression. When my friend had it, it he said that he just couldn't accelerate and had to pull to the side of the road. The engine turns but it wont turn over. It seems to spin freely. My friend said he talked to an Audi dealer and he said it sounded like a water pump! That just didn't sound right to me. I'm new to Audi so be nice, but any advice would be much appreciated.
