Does the Ignition Module in Your BMW Need to be Replaced?by techplusaadmin March 4, 2018
Today our cars are run mostly off of electrical currents and technology, which includes several different control modules. In general, control modules are like little computers that receive input from various sensors throughout the car and make adjustments to the vehicle’s processes in order to optimize functioning. Some BMWs encounter control module failure after a period of time, and cases of ignition control module failure have been especially documented. It’s important to know when your own BMW’s ignition module needs servicing or replacement. In this article we’ll go over how important the ignition module is for your car’s functioning, how to recognize signs of failure, and what you can do to fix it.
What does the ignition module do for your BMW?
All of your BMW’s control modules are critical for its functioning; however, one control module is especially important, as it dictates whether your car will even start. The ignition control module plays an important role in engine starting as well as engine timing. The ignition control module, also referred to as the electronic spark control module, controls the engine’s timing in order to properly start the car initially, but also to keep the car running optimally, as it compiles information from various sensors to adjust the engine timing according to the car’s needs and environmental conditions such as the driver’s unique driving habits.
Common signs of ignition module failure
Since the ignition control module plays such a critical role in your BMW engine’s functioning and timing, it’s no wonder that drivers experience these common troublesome symptoms if it begins to malfunction or fail prematurely:
Engine misfiring and starting issues
Engine performance issues such as misfiring are inconvenient and highly concerning for drivers. Usually this is one of the first signs that drivers notice when the ignition control module begins to fail. Your BMW will not be able to start if the ignition control module has failed, and will likely need to be replaced.
Decreased power and hesitation
If your BMW encounters decreased power and/or hesitation upon acceleration, the problem could be related to any number of things; however, an ignition control module will not be able to appropriately adjust your engine’s timing to allow for optimal acceleration, which can lead to acceleration and power issues.
Lowered fuel efficiency
If your BMW’s engine isn’t able to run efficiently, one of the first things to go is your good gas mileage. Your engine isn’t able to burn fuel optimally when the ignition control module is encountering issues because the engine timing is usually off; eventually fuel becomes wasted.
Along with engine misfiring and loss of power, engine stalling is another performance issue that BMW drivers tend to experience due to ignition control module failure. When the engine timing is inconsistent due to a faulty control module, the ignition and combustion processes are interrupted.
How to provide the right servicing for your BMW
Although the ignition control module isn’t really meant to be replaced in your BMWs service plan, it may need to be serviced or updated from time to time. Proper preventive care can help you to avoid ignition control module failure.
- Enlist the help of a BMW expert.
- Follow the manufacturer-recommended maintenance schedule.
- Take note of troubling symptoms and bring them to your specialist for diagnosis right away.
- Research the common issues that BMWs face and consult with your BMW specialist to anticipate your car’s needs and repair work.
If you do encounter ignition control module failure, you will want to bring your BMW to a shop that specializes in German-engineered cars. In order to effectively attend to a failed ignition module in a BMW, it requires expertise, knowledge, and experience working with the specific part in BMW cars alone.
