Rear Main Seal Retainer, Flange
- Description:
Genuine Audi Rear Main Seal Retainer 078-103-171L is a precision-engineered flange component designed to secure and house the rear main seal at the back of the engine block. This genuine OEM part fits the Audi A4, S4, A6, and S6 equipped with 2.7L and 2.8L engines built from May 1998, as well as the Allroad from June 1998 through September 1999. The rear main seal retainer works by providing a rigid, precisely dimensioned mounting surface that keeps the rear main seal properly seated and contained under the stress of continuous crankshaft rotation. Even minor dimensional inconsistencies in an aftermarket flange can cause seal misalignment, leading to oil leaks, crankcase pressure issues, and accelerated seal wear. Because this component must conform exactly to Audi's engineering tolerances, OEM is the only reliable choice — aftermarket versions frequently use inferior castings that fail to maintain a leak-free mating surface over time. Searching for an Audi A4 S4 A6 S6 OEM Rear Main Seal Retainer or the part number 078103171L ensures you land on the correct, factory-specified component rather than a generic substitute. Every genuine Audi part delivers the fit and longevity your vehicle was engineered to depend on. Purchase with confidence from Audi Henderson, an authorized Audi dealer backed by the full manufacturer warranty.
