Over tightened lug nut problem 90 sport 90 q

[John Stanton]

Well nothing is ever easy, went to rotate my tires today and guess what one
lug over tightened by the Audi dealer at last service.  Here's the problem.
I used a pipe extended off the standard OEM lug wrench and it slips off
stripping the nut.  I repositioned it and stripped it some more.  I know I
know, should have known better but the situation exists.

So help what do I do now.

Thanks

John
