Ignition module failure on BMW vehicles is a very common fault. The ignition module sends signals to your car’s electrical system to ignite the battery and to keep the car running smoothly, so if your BMW has been having trouble starting up, stalling out randomly, or has had other electrical issues, this could be the culprit. If the ignition module itself isn’t functioning, your BMW won’t start reliably—or at all.
What Does the Ignition Module Do in Your BMW?
Your BMW’s ignition module is like the brain of the ignition system—it commands when and how your spark plugs fire. Without it, your engine won’t start or run properly. This small part lets the spark plugs fire the air-fuel mixture within your engine’s cylinders at the right time. When things go out of time, you’ll notice things like misfires, lack of performance, or your car not even starting.
Imagine if the ignition module starts to fail — it’ll be the equivalent of wet matches trying to start a fire. It’s either going to suffer or it’s just not going to happen. That is why having it in proper working order is vital to the performance and reliability of your BMW.
How To Tell if Your BMW Ignition Module Is Malfunctioning
As having a properly functioning BMW ignition module is an essential part of the performance of your vehicle, when something is going wrong with this, you will want to know.
- Engine Misfire or Stalling: If you are having your BMW sputter or not running regularly, more than likely, your ignition module has failed. That appears when the module fails to send signals properly to the spark plugs.
- Difficulty Starting: If your BMW has difficulty starting, this could be a sign of a problem with the ignition module. If your engine cranks but won’t start or takes a few tries before it cranks, this part may be the culprit.
- Loss of Power or Poor Performance: A failing ignition module can cause lag, sluggish acceleration, or underpower. That’s because the BMW is likely fighting to keep speed and make its vehicle mechanics react to throttle input.
- Check Engine Light: Although a check engine light can signal a variety of concerns, a failing ignition module will frequently set DTCs, or diagnostic trouble codes, about the ignition system. Our technicians can run a quick scan to identify if your ignition module is at fault.
- Overheating Ignition Module: If the ignition module is an older part, it can sometimes overheat. This will cause the BMW to abruptly turn off while in motion and not restart until it has cooled down.
Why Timely Replacement is Essential
Overlooking the indications of malfunctioning ignition module will cause progressive engine problems in the future. For example, repeatedly misfiring can overheat the catalytic converter and cause costly repairs. In addition, a faulty ignition system can jeopardize your vehicle’s performance and safety. Commitment to addressing issues with your ignition module can ensure your BMW remains reliable and performs well for many years.
