Re: which audi transaxle is it
AFAIK, the 012 has the same bell housing bolt pattern as the model 01E, not the 016.
Andy, I don't recognize that number you posted. The part number and code will be stamped at the bottom adjacent to the differential side cover (on the drivers side). It should read 012 XXX XXX XXX, with the last three places being the lettter code. Though it doesn't appear in the photo, there is often a label with the part number on top of the housing which rarely stays affixed.
Is this transaxle from a USA vehicle?
