OXS light on and I don't know why!

[Delt133@aol.com]

Greetings everyone,

I was teaching the girlfriend how to drive stick the other night and the OXS
light came on.  Now, I know that teaching her how to drive a stick shift on an
old cable clutch Audi is a particularly mean thing to do, (to her as well...)
but I got a new clutch installed about one thousand miles ago and I thought
both were up to it.  After a kinda harsh jackrabbit start the idiot light came
on.  The car has been running just fine and felt even better than usual when I
took it on the highway right afterward to let it relax.  I just don't get it.
Any input would be gratefully apreciated (that light is getting rather
annoying).  

Thanks in advance,
John
