BMWs can experience problems with their ignition module, which is a component responsible for starting your car. By sending a spark to the BMW’s coil, the ignition module acts much like a switch that starts your car when it is turned on. When the ignition module is turned off or flipped backward like a light switch, the vehicle turns off, too.

Without an ignition module, BMW models would not be able to start. As you can see, this is quite an important BMW component. Let’s take a closer look at what you should look for if your ignition module stops working.

Indications of a Problem

If your BMW has turned off and simply won’t start again, a faulty ignition module may be the culprit. This is perhaps the most obvious sign that the ignition module needs to be checked. Other, less obvious signs that your ignition module may be failing include a loss of power and sudden stopping. If your BMW overheats frequently, this may also be a sign that your ignition model is malfunctioning.

Testing the Ignition Module

Without taking your BMW to a mechanic, there are a few ways that indicate a faulty ignition module may be the cause of vehicle problems. If you suspect a loss of power, you can use a light timing tester to see how strong the output from your ignition module is by connecting the timer to the battery and watching for a blinking signal. If the timer does not blink, the ignition module is likely faulty.

Repercussions of Overheating

If your BMW begins to overheat frequently, this could be an indication that your ignition module is faulty. A telltale sign of this occurrence includes your vehicle stalling and the temperature gauge reaching temps that are much higher than normal.

In the worst-case scenario, smoke might come from the engine. Usually, it isn’t the ignition module that is smoking, but other components involved in your engine.

If the ignition module is causing your vehicle to overheat, you may also experience reduced fuel mileage, a stutter in the engine, or electrical shortages. When your BMW overheats, it is a serious matter, and you should take your BMW to a trained technician as soon as possible to avoid costly repairs.

Preventing Serious Problems

By continuing to drive with a faulty or worn-out ignition module, you could experience more serious issues with your BMW in the long run, including warped metal due to extreme heat. This is the worst case scenario and would require an engine rebuild. However, regular service appointments allow our certified technicians to check out the ignition model and let you know of any potential issues. Our technicians are factory-trained, which means they have extensive knowledge of BMW models and their inner workings.

Cost of Repair

Fortunately, repairing or replacing your BMW’s ignition module is not too costly. Repairing your vehicle’s ignition module is certainly worth it. After all, without this part, you would be unable to start your vehicle. Reach out to our service department to speak with our trained technicians regarding our affordable costs. Once your ignition module starts to go out, many components begin to follow suit. Ignition coils are also lumped into this category, although they are slightly different. With an inspection and diagnostic check, we will be transparent with our findings and allow you to choose what steps to take in repairing and servicing your BMW.
