Thread: AUK Engine Timing Chain

  1. #1

    Default AUK Engine Timing Chain

    About to pick up a 2005 A6 with the AUK (3.2L V6) engine. Looking at vagcat, it's got a timing chain instead of a timing belt. All my previous cars (90, 100, A4) have been timing belts so this is an all new experience for me. Do I need to replace the chain? Ever?

    If it stretches, yes, but I do believe that you'll need to monitor the guides fairly closely.
