Audi Repair & Service in San Marcos, Texas

About Audi Service at Riley Auto Care

Audi's "Vorsprung durch Technik" — advancement through technology — is more than a slogan. It describes a genuine engineering philosophy that has produced some of the most sophisticated and rewarding vehicles on the road. The A4, Q5, and S4 are benchmarks in their respective segments, combining precise handling, powerful turbocharged engines, and the legendary Quattro all-wheel drive system. Riley Auto Care & Transmissions has the expertise and diagnostic equipment to service Audi's advanced technology properly.

Audi's S-Tronic dual-clutch transmission (also known as DSG) is shared with Volkswagen and requires the same specific fluid and service procedures. We perform proper S-Tronic services using Audi-approved G 052 182 fluid to prevent shudder, hesitation, and premature clutch wear. For models equipped with the conventional Tiptronic automatic, we provide fluid and filter services using the correct ZF-specification fluid.

Audi's Quattro all-wheel drive system — available in multiple configurations including Torsen center differential and Haldex clutch-based systems — requires regular transfer case and rear differential fluid service to maintain proper torque distribution. Timing chain issues on the 2.0T TFSI engine are also well-documented, and we can diagnose and address chain stretch before it causes serious engine damage. Serving Audi drivers throughout the region, we provide the European-grade expertise your vehicle deserves.
