Porsche Repair & Service in San Marcos, Texas

About Porsche Service at Riley Auto Care

Porsche builds some of the most driver-focused, technically sophisticated vehicles in the world. The 911 is the benchmark sports car against which all others are measured, while the Cayenne, Macan, and Panamera bring Porsche's engineering philosophy to SUV and sedan buyers. These are precision instruments that require service from a shop with genuine European import expertise and the right diagnostic equipment. Riley Auto Care & Transmissions is equipped to service Porsche vehicles with the care they demand.

Porsche's PDK dual-clutch transmission is one of the finest gearboxes ever produced — delivering lightning-fast shifts with exceptional efficiency. However, it requires specific Porsche-approved ATF fluid and precise service procedures to maintain its performance. We perform proper PDK fluid and filter services to keep these transmissions operating at their best. For older 911 and Boxster owners with the Tiptronic automatic, we provide fluid and filter services using the correct ZF-specification fluid.

One of the most critical service items for older Porsche 911, Boxster, and Cayman models with the M96 and M97 engines is the Intermediate Shaft (IMS) bearing inspection. IMS bearing failure can cause catastrophic engine damage, and we can assess bearing condition and advise on the appropriate course of action. Serving Porsche owners throughout the region, we provide the European-caliber expertise these exceptional vehicles require.
