Yeah my check engine light came on about three weeks ago, and I drove about a week with it on. I finally got it checked out at Autozone came up with codes: P0440 Emission Control Malfunction (What the crap is that supposed to mean? -also, my exhaust has been smellin like sulfur since I got the car I dunno if that's related.), P0171 Running too lean (Would it be alright to drive another week without getting that fixed?), and P0411 (Forgot what the reading on that code was). I love my VR6 jetta to death and I plan on having it for awhile.. Any help on these would be highly appreciated.
