Keeping a Audi RS 6 Avant Performance Reliable in Phoenix
Arizona heat is the hardest test a Audi will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a RS 6 Avant Performance that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for RS 6 Avant Performance owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Audi RS 6 Avant Performance, a pre-purchase inspection shows what the paperwork does not.
