If you can barely see at night because your BMW’s headlights are too dim, it’s probable that the alternator is going bad. The alternator may be no longer unable to produce a minimum of 13 volts of power, which is what your BMW needs for various accessories and components. You may also have problems with the vehicle lights flickering or they may be too bright if the alternator is producing excess power. Let’s talk more about signs that the alternator is going bad below.
Battery Warning Light
Your BMW is going to give you a warning by turning on the battery light on the dashboard. This is an indication that there is a problem with the Beemer’s electrical system. In some cases, this problem could be the alternator or it could be that it’s time to replace the battery.
Frequent Engine Stalling
If you are having problems with your BMW stalling frequently, it’s possible that the alternator is not generating enough power to supply the spark plugs with the electricity that they need. When this happens, the engine will misfire and install frequently because the spark plugs are not firing properly.
Hard Starts/Dead Battery
Another sign that your alternator is going bad is difficulty getting your BMW started because the battery has discharged. The alternator charges the battery so you never end up with a dead battery. If you have been ending up with a dead battery lately, the alternator could be malfunctioning.
Malfunctioning Accessories
Speaking of malfunctions, your BMW’s accessories are going to start to malfunction and slow down if the alternator is not providing enough power to them. This can include things such as the radio, the navigation system, and your power accessories such as the seats and windows.
Overheating Electrical System
We mentioned above that the minimum amount of voltage that an alternator should produce is 13 volts. The maximum amount of voltage that the alternator should produce is 14.5 volts. If the alternator malfunctions and produces more than this, it will overheat your BMW’s electrical system.
Strange Growling Noises
Finally, if you hear strange growling noises coming from the engine, the alternator could be making those noises. Sometimes, the alternator will start to grind when it is wearing out. It may also start to squeal if there is a problem with the alternator belt.
