Widespread Complaints: Serious Electrical Issues in BMW & Ways to Fix Them

Of late, BMW drivers have reported facing a lot of electrical issues in their vehicles that make it difficult for them to drive their high-end cars. If these electrical issues are not identified and fixed immediately then it can also affect the functioning of the other components and lead to costly repair bills.

There are certain electrical malfunctions that BMW drivers need to know about so that they can initiate remedial measures quickly. Here in this article, we will discuss the serious electrical issues affecting BMWs and ways to fix them.

Battery Drain Problems

One of the pressing problems affecting many BMW models is related to the functioning of the battery as owners are often reporting excessive battery drain even while their vehicle is parked. Most of the time it is observed that this problem is caused due to malfunctioning IBS (Intelligent Battery Sensor) software or faulty electronic modules that don’t enter sleep mode.

Due to the excessive drain from the battery, BMW drivers are often faced with other issues in their car ranging from slow engine crank to dim lights or the need for frequent jump-starts. You need to first inspect the battery of your vehicle for excessive power draw by using a multimeter.

Besides that, updating the software of the battery to the latest version from a BMW dealership is also the need of the hour. Furthermore, if you are driving with a faulty IBS under the hood of your high-end car then replacing it immediately is going to solve your battery woes.

Moreover, you need to make sure that no aftermarket accessories are fitted in your BMW as it can put huge stress on the battery to supply an adequate amount of power.

Bad Alternator

The alternator in your BMW is responsible for providing the electrical components with the required power when the car is running and also charging the battery in the process. Now, issues with the functioning of the alternator can have a devastating effect on your vehicle.

Whenever you are driving with a bad alternator under the hood of your vehicle, you are going to be faced with erratic electrical behavior, flickering dashboard lights, power loss, or complete shutdown of your engine. Now, when this problem goes unaddressed for a long time it can lead to complete failure of the charging system due to continuous usage & excessive heat exposure.

You should start by checking the functioning of the alternator by diagnosing the battery voltage when the engine is running and the output should be between 13.5V to 14.5 V. However, if the reading comes out to be too low then the alternator might need a replacement.

In addition to that, you must also inspect & replace the alternator belt if it appears to be loose or worn out completely. Besides that, make sure your battery is in good condition as a weak battery can put a lot of stress on the alternator.

Malfunctioning Adaptive Headlights

Most of the modern BMWs that people own come equipped with adaptive headlights that adjust based on your steering input and road conditions. At times, it is noticed that the headlights encounter problems because of defective actuators, burned-out balls, or software bugs leading to inconsistent lighting or complete failure of the system.

If you come across malfunctioning adaptive headlights then you need to inspect the fuses and get them replaced if necessary. Furthermore, you should also get the adaptive headlight module reset & replace the parts that are creating problems in its functioning.

Power Window Failure

There are certain BMW models that encounter power windows issues which can be really frustrating to deal with as you won’t be able to use your windows. Most of the time the problems are caused due to faulty window regulators, broken motors, or electrical issues.

You should start by inspecting the window switch and fuse to rule out electrical issues in them. If you come across a faulty electrical motor then replacing it would ensure complete functionality of your windows. Some experts also opine that you must apply silicone lubricant to the window tracks to prevent any kind of additional strain on the motors.

Finally

The above-discussed factors are some of the electrical components in your BMW that encounter frequent troubles. In fact, the moment you notice anything is wrong with the functioning of these components then don’t hesitate to get in touch with a certified mechanic to get your electrical issues fixed at the earliest.
