CEL came on while I was driving my 2001 S4 home the other night. I was getting on it a little bit, boosted to about 14-15. Then I noticed that the CEL had come on, so I stayed in vacuum the rest of the way and haven't driven it since. The car was running just fine and I cannot find anything obvious. It doesn't seem like a boost leak, but the situation that the light came on in makes me think thats a possibility. If someone could come and pull the codes with vag I could offer cash for their time. I am in the college area of San Diego. Thank you.
