Alternators

Your BMW's alternator is responsible for charging your vehicle's battery when the engine is running. The alternator works to convert mechanical energy to electrical energy so the battery can stay running all day, along with other important systems in your vehicle. Because electricity is so important for the proper operation of your vehicle, it is vital to ensure your alternator is running properly. You can keep an eye out for a range of alternator problems that can alert you to make a replacement to the part if needed. You might have a BMW that came with an alternator warning light that will let you know of any potential problems. If your indicator light comes on but you notice your headlights are flickering or becoming dimmer and dimmer, this is a sign that something might be wrong with the alternator. You also might start to notice a drop in power on the road. Your battery also might start to die frequently, which can indicate an alternator problem versus a battery problem. Make sure you take these problems seriously and get the alternator looked at. You can find OEM BMW alternators here on our site when you need to grab a replacement.
