My local dealer parts guy said that's the main reason (or part of the 
problem) for the sludge issue.  The Audi 1.8t holds less oil (than say 
the VW 1.8ts).  So they are having a larger problem with sludge.  They 
now use only synthetic oil in the Audi 1.8ts.

Seems to me that adding an additional external oil cooler would be an 
effective way to increase oil quantity...
