A used Audi timing chain tensioner, OEM part number 079109507R (also replaces 079109507Q), from a donor vehicle. This tensioner maintains proper chain slack on 4.2L V8 and 5.2L V10 engines—including the 4.2L 4163CC V8 diesel and gas variants—across Audi and VW applications. A failing tensioner often produces a rattling noise from the front of the engine on cold starts, as hydraulic pressure drops and the chain loses its grip. Without correct tension, the timing chain can skip, risking valve-to-piston contact.
