Timing Chain/Tensioner Failure or Rattling on Cold Start
Often reported
In documented cases, the guide or tensioner can break or collapse, causing chain slack, camshaft misalignment, and out-of-spec timing values. Additionally, many owners report a brief rattling/clicking sound (1-3 seconds) from the timing chain area on first cold start; Audi linked this to one of the upper chain tensioners in a Technical Service Bulletin issued in March 2015.
