Electrical System
21 of the 41 complaints (51%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Power Train
7 of the 41 complaints (17%) mention the powertrain. Powertrain complaints can range from rough shifting to loss of drive. We road test, scan for stored codes and inspect fluids before recommending any repair. See our auto repair page.
Forward Collision Avoidance
7 of the 41 complaints (17%) mention driver-assistance and stability systems. Driver-assistance and stability systems rely on sensors and software. We scan for stored codes and diagnose sensor and wiring faults. See our check engine light diagnostics page.

Keeping a Audi A6 Allroad 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 A6 Allroad 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 A6 Allroad 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 A6 Allroad, a pre-purchase inspection shows what the paperwork does not.
