OEM Audi Alternators

Refine Results

Alternators distribute power from a car's battery to its systems that run on electricity. It does so via a complex of wires, fuses, and relays. In short, a battery starts a car, but a factory alternator keeps it running.

When Should You Replace Your Alternator?

It can be hard to tell. Alternator failure often happens without warning. Luckily, though, beyond a dashboard light turning on, there are a few signs that your alternator is going bad. One symptom is flickering headlights, if not trouble with other lights. Another is your car radio working erratically. Yet another sign is the smell of burning around your battery or alternator. Other symptoms include your engine squealing, a dead battery, and the worst: total electrical failure. You can even cause an alternator to go out yourself if you jump-start your Audi incorrectly or overload it by installing incompatible accessories. To figure out the problem, run an inspection and a charging system test. Change your alternator if needed. Otherwise, it's a good idea to replace an alternator every 80,000 to 150,000 miles. That's around every seven years. Refer to your owner's manual for more details.
