This thread got me wondering if the turbo removal in the 2.7tt A6 were 
the same PITA? Actually my wife drives an Allroad, but it's based on the 
same C5 chassis as the A6. The warranty will run out in 3 years after 
which I will be on my own. I guess I am too spoiled by the easy access 
to turbos in my previous Audis with in-line engines.
