Hi all... I've been posting in the A6 forum but to no avail, so I'm hoping someone can help me here. My emission control fault lamp on the dashboard has been switching on, off, on, off and on again (currently on). I'm getting it checked out tomorrow, but was wondering if anyone had any ideas? Here are my original posts: http://www.audi-sport.net/vb/showthread.php?t=65969 Cheers! A.
