Alternators

Refine Results

Your car battery starts your Audi model, but it needs another part to charge it: the alternator. The alternator is a component of the charging system, and it is designed to run many electrical systems. For example, the alternator can light up your dashboard lights, run the windshield wipers, and warm up the heated seats.

What Are the Signs of a Bad or Failing Alternator?

It's not hard to spot the signs of a bad or failing alternator. In fact, they are easy to see. Some of the most common symptoms you can look out for include:

  • Flickering headlights
  • Radio malfunctions
  • A burning smell
  • Engine whines
  • A dead car battery

If you think your Audi vehicle has alternator issues, the best thing you can do is test and inspect the charging system. On average, it is recommended to change the alternator every 80,000 to 150,000 miles. That's equivalent to about once every seven years.
