This used OEM center timing belt cover (part number 078109123AD) is a genuine Audi/VW component, also replacing 078109107M. It shields the timing belt on 2.7L and 2.8L V6 engines—specifically the 2671cc turbocharged and 2771cc naturally aspirated DOHC units found in A4, A6, S4, and Passat models. A cracked or missing cover can let debris contact the belt, risking failure.
