Vacuum help
I have a 2004 A4 Quattro 1.8T with a very small vacuum leak. I have tried the engine starter spray trick but I had no luck. I think this leak is very small which is probably why. My check engine light stays on too.
I've been told that these vehicles have a secondary air system. Which I have no idea what that means. Can someone please help me?
