Top Signs Your BMW Needs An Ignition Module Replacement

25 Sep, 24

If you have a problem with your BMW starting or if it feels somewhat underpowered a bad ignition module could be the problem. Although this issue may appear simple, neglecting it leads to more complicated issues and can leave you stranded when you least expect it. The ignition module is an important component and it has a great influence on the performance of any vehicle including BMW. It plays the role of regulating the frequency of sparking of the fuel in the engine of your vehicle. If your car has a bad ignition module, then it will not start — or if it does start, it will not run smoothly. Ready to know what the most obvious indicators are that your BMW requires an ignition module replacement? Let’s check them out!

Symptoms of a Bad Ignition Module

Difficulty Starting the Engine

It is easy to spot that there is something wrong with your BMW’s ignition module if you find it hard to start the engine. Some common symptoms that indicate a dead ignition module include a car that takes time to start, one that takes a long time to crank, or doesn’t start at all. When the module is out of order, they do not fire the spark plug which makes it difficult for your engine to start.

However, it is also possible that a weak battery or a failing starter is the cause of hard-starting, but the ignition module should not be ruled out. If the problem remains after checking the performance of the battery and starter, having a professional examine the ignition system can prevent a breakdown and save you from unnecessary expensive repairs later on.

Engine Misfires

Another indicator that your BMW’s ignition module could likely require replacement is rough running and misfires. When the ignition module is weak, the spark plugs won’t fire in the intended sequence resulting in engine misfiring. Inaccurate firing may cause a rough or jittery feeling while cruising down the road or when you stop at a light.

You may also observe that you experience some sluggishness in your car and you can feel it stutter or hesitate as you accelerate or step on the gas. If these misfires are not corrected they will harm your engine over time so it must be fixed as soon as possible.

Sudden Loss of Power

Have you ever experienced a power breakdown with your BMW while in motion? This is another sign of ignition module failure so if you notice your car behaving weirdly, you should take it to a mechanic. In certain instances, failure of the ignition module may lead to loss of power on the engine and this is always a cause of worry. This may occur when you are getting from a standstill into motion or in normal operational conditions on the road. Power loss is inconvenient and can compromise the safety of drivers, especially when power is interrupted mid-highway.

What Should You Do If You Observe These Symptoms?

• Get a Diagnostic Check: If your BMW is exhibiting any of the symptoms that indicate ignition module failure you should take it to an auto repair shop of your choice for diagnosis. They can decide if the ignition module is the one that needs replacement or if it’s some other component.
• Replace the Ignition Module: If the diagnostic test shows that the cause of the problem is in the ignition module, then it should be replaced without delay. Replacing the module will bring the engine to normalcy and will not cause any more problems.
• Follow Regular Maintenance: To prevent any more problems with the ignition module in the future, always stick with your BMW’s regular servicing times. Some of the problems that the car could develop can be detected during tune-up and Inspection so you can get solutions early before they worsen.
