Re: removing taillight (tracing battery drain)
I agree w/Andrew Duane's idea - I'd never heard of the 90Qs having the
chafing problem on the trunk lid wire harnesses until I traced a battery
drain to it on mine last weekend...it was the harness on the driver's side
of the trunk. It would turn the trunk light on partially (about 10 volts).
It was right where the wire bent when you closed the trunk. It was a b**ch
to find. Disconnect the harness in the trunk and see if that eliminates
your drain, and then you have to go find which circuit is grounding.
All Audi's seem to be alike!!!..........SLM
