This is a genuine engine timing chain guide, part number 021109469, for select Audi, Porsche, and Volkswagen engines. It is a right outer guide that works on the slack side of the timing chain. It helps keep the chain routed correctly and the engine timing stable.
The guide fits right outer and crankshaft-to-auxiliary chain applications, including select Porsche Cayenne models. It is used as a replacement when a guide is worn or damaged, or when chain slack, noise, or poor chain tracking shows up during timing system repair.
Before installing, verify the engine code, position, and chain path. Inspect related timing components for wear, and confirm fitment against the vehicle's service information.
