Re: "pulling" trunk codes


I don't have the stuff w/ me at home, but I'll have a look at the
service/repair fiche and manuals for the Torsen (MB/RR) Urq's tomorrow.
Does your dealer sell you factory repair manuals if you desire to purchase

I'll try to check with Audi Finland as to the existance of a lock (other
than the manual one) on any Audi rear diff other than the V8/A8 tomorrow.
The tech guy has been away in training in Ingolstadt and on holidays to
boot, so this whole thread I've had to rely on other sources...

BTW, Phil, what gearbox/diff codes does your car have?
