Which A6 cars came with the 01E Quattro?
 

Been trying to track down a cheap 01E. I need to steal the center diff out of it. So I've been attempting to make a list of all the Audi models that had the 01E. (Quattro, not FWD)
Here's My List:

2001-2003 B5S4

2001-2005 C5 Allroad w/2.7T

Not sure about A6's, so I would appreciate it if someone can fill this in:

200? - 200? C5A6
Not sure what motors either.
2.7T 30V? 4.2L 40V? 2.8L 30V?

How about B6 A4's?

I feel like I might be able to track down a 01E 6SPD from an A6 easier than from an S4. I think the junkyards scrap an S4 and all they see is $$ signs. Most of the S4 boxes around me are selling for $1500+

Thanks!
