v-belt sizes

[PeterBergin at aol.com]

I would go with SJM or Blau, both know the car well.  Scott at  SJM is a 
strong supporter of our cars!
 
On my 200, it was a good idea to replace the tensioning bolt as they do  tend 
to wear.  But a quick visual inspection upon removal would show its  
condition.
 
I have had bad luck buying some specific Audi parts at some of the import  
chain stores (IMHO).
 
You can remove the belts and bring them to a good auto parts store and they  
should have a measuring tool.
