Audi B9/B9.5 S4, S5, SQ5, RS5, C8 S6, S7, D5 S8 Rear Sport Differential Service Kit

Complete rear differential service kit for Audi B9/B9.5 S4, S5 and SQ5 models equipped with the optional sport differential.

Audi lists these as "lifetime" fluids. This means that there is technically no set replacement interval. However, if you do regularly push your vehicle hard (especially if you go to the track), we recommend servicing these fluids every 40k miles. If the vehicle typically just sees casual day to day commuting, you can extend that interval to around 50-60k miles. 

Fluid Capacity
When performing a fluid service, the refill capacity of the gear oil section of the 0D3/09R rear sport differential is 0.95L. 

Only High Quality, Proven Parts from our Experienced Service Team
These are the same fluids and parts that we use when servicing the rear sport differential on an Audi B9/B9.5 S4, S5, SQ5, C8 S6, S7 or D5 S8 models in one of our shops.

Unlike other online stores, we actually repair and service vehicles at our two, full service shops. Due to our hands on service experience, this kit includes ALL of the actual parts you'll need to perform this service. Other online stores that don't perform service work are blindly trusting information they've found to build these kits and often don't give you everything you need or try to sell you extra, unnecessary parts.

Since NGP actually performs repair service and maintenance on vehicles, the parts we've chosen to include in this kit have been selected based on thousands of hours of service work performed by our expert technicians. Our service department has very high standards and only uses high quality parts from proven OEMs.
