Quattro all-wheel drive is one of the biggest reasons drivers choose Audi, giving confident handling in Tennessee's rain and occasional winter ice. But an AWD system has more moving parts than a front-wheel-drive setup, and skipping its specific maintenance needs can lead to costly driveline repairs down the road.
Quattro systems rely on very small differences in wheel speed to distribute power correctly, which means mismatched tire tread depth from front to rear can put the drivetrain under constant strain. Even replacing just two tires instead of all four can throw the system off. We check tread depth at every service and recommend rotations to keep wear even across all four corners.
Quattro's rear differential and transfer case use specific gear oil that lubricates and cools the components as power shifts between the front and rear axles. Unlike engine oil, this fluid isn't part of most owners' regular routine, but it breaks down over tens of thousands of miles and needs periodic replacement to prevent premature wear on the differential gears. We follow Audi's factory intervals for this service.
