Audi experts, The OXS light just came on in my 4000Q and it is annoying as heck. The car seems to run ok though. Do I have some maintenance that I have to do? or is this a reminder thing? How do I reset the light??? Any and all help is appreciated. Thanks in advance. Happy holidays. Doug Evans dougev@newpig.com 1985 4000SQ 1988 90Q 1984 325e
