Signs Your Alternator Is Beginning to Fail

When Your BMW Won’t Hold a Charge, it Could be Something other than the BatteryIt’s certainly not something you want to think about, but if the alternator in your BMW fails, you could be stranded. That’s because the alternator is responsible for the electrical operation of your vehicle, including charging the battery once the engine gets turned on.

Here are a few signs that may very well indicate the alternator in your BMW is faulty, getting old and worn out, or is at risk of failing. If it fails and you don’t pay attention to those warning signs, you could find yourself stranded in a parking lot, on the side of the road, or anywhere else, even in the middle of the night.

Warning Sign #1: Dim headlights.

If you’re driving at night, and you notice the headlights don’t seem as bright as they should be, it may be one of several potential problems. The alternator might not be charging the battery properly and may not have enough voltage to fire the spark plugs, take care of all the electrical operations, and more. It may only be a matter of time before your car dies and you have to get to the side of the road or into a parking area quickly.

Warning Sign #2: Certain electrical functions begin acting up.

If the air conditioner blower, wipers, turn signals, and other devices begin working intermittently, it could be a sign that the alternator is having difficulty maintaining consistent voltage and amperage throughout.

Make sure you get your vehicle to an authorized BMW service center as soon as possible once you notice these things occurring.

Warning Signs #3: Your battery seems to be dying often.

The battery might be dead one morning and you simply get out of the car and jumpstart it with your other vehicle. You don’t think twice about it.

However, even though that might have been due to lights being left on or some other simple oversight, the alternator may not be charging the battery properly while driving. If you have to start your car a few times, purchased a new battery, and it keeps doing that, it could very well be your alternator.
