Alternators

You might not think about it much, but the alternator is a vital part of your vehicle's charging system. Your car needs electric power to run the ignition and also for all the electronic controls and gadgets that are on board. This power is delivered by the alternator that acts as a generator when the car is running. The alternator helps to recharge the battery and power the electronics in the vehicle while you are driving. If you notice that your lights are dim, you constantly have a dead battery, you have a service engine light on, or your engine is stalling, you may need a new alternator. Failing alternators also sometimes make grinding noises. If you have electric problems in the car, you may need to replace your Audi alternator. The best thing to do when you need to replace the alternator is to use an OEM part made for your Audi. While the alternator is not something that needs to be replaced often in your vehicle, it is a vital part of your vehicle that you cannot drive without. Here at Audi Parts Nationwide, you can find genuine OEM alternators for your specific Audi vehicle. Check out all of our alternators below!
