A4 commuter, Q7 family hauler, or RS weekend toy — M&S Autohaus services Audi with OEM-spec parts and dealer-level diagnostics, minus the dealer wait and markup. Serving Sterling and all of Northern Virginia, by appointment.
Audi maintenance runs on the factory interval schedule — oil services with VW-group-spec oil, filters, spark plugs, and brake fluid on time. TFSI engines are known for carbon buildup on intake valves and for water pump and thermostat housing leaks; we treat both as routine, scheduled work instead of emergencies.
S tronic and Tiptronic transmission services on the factory schedule keep shifts crisp and protect the gearbox — one of the most skipped and most important services on higher-mileage Audis. Quattro systems get the right fluids at the right intervals.
S and RS cars are welcome, stock or building. Intakes, exhausts, suspension, big brakes, and the tasteful style work the site shows across the gallery — color-matched, never loud. Dealer-level scan tools handle fault diagnosis, coding, and adaptations in-house.
Yes. Direct-injection TFSI engines build carbon on the intake valves over time — rough cold idle and lost low-end power are the usual signs. Walnut blasting on schedule restores how the engine was meant to run.
Yes, stock or modified. Performance work is core to the shop — intake, exhaust, suspension, and brake upgrades that hold up, on cars we drive ourselves.
Per the factory schedule for your specific gearbox — skipping it is one of the most expensive shortcuts on a higher-mileage Audi. We check the actual service history and tell you straight whether it's due.
No. Independent service with documented OEM-spec parts is protected by the Magnuson-Moss Warranty Act. Our invoices itemize everything for your records.
