Alternators

Keeping your Audi's alternator functioning properly is crucial to the operation of various systems. While the battery is an important part of your vehicle that helps contribute power to systems, it wouldn't be able to function without the help of your alternator. Your engine is able to stay running all day thanks to the alternator, which supports the battery and recycles power. Having a quality alternator under the hood is so important. You can pay attention to several signs that something might be going wrong with your alternator so you can make a replacement as soon as possible. It's important to pay attention to if your engine is having difficulty starting, because this can be one of the first signs of something being wrong with the alternator. While difficulty starting can come from many different areas, you definitely want to get the alternator looked at. The alternator wearing out can even cause your battery to fail, as well. It's important if you figure out if it's an alternator problem so you can eliminate problems with the battery. Dashboard lighting or headlight lighting might start to flicker or dim over time if the alternator is wearing down. Find OEM Audi alternators here on our site.
