Mike,
I am almost certain that they are not interchangeable. When I pulled the 
bearings out in my S6 I had to use a 3/4" breaker bar over a 1-3/8" 
socket and I had to lean onto it with all my weight to get the puller 
remove those massive beefy bearings. My gut tells me that the A6 would 
have a lighter duty arrangement.

And yes, IME different suffixes always signify non-interchangeable 
parts. The only exception is the suffix "x" in the end that is added to 
a rebuilt part.
