The Best Repair Shop in Myrtle Beach to Fix BMW Ignition Coil Issues

BMW Ignition Coil

The ignition coils in a BMW play an important role in providing the spark that ignites the fuel in the engine. When the ignition coils fail, it can cause a variety of problems with your BMW’s performance, such as misfires, decreased power, and even engine damage. Let’s look at five signs of BMW ignition coil issues and the reasons they occur.


One of the most common signs of ignition coil issues in a BMW is misfires. A misfire occurs when the spark that ignites the fuel in the engine fails to occur or occurs at the wrong time. This can cause your BMW to run rough, jerk or hesitate while accelerating, or even stall. If left unaddressed, misfires can cause damage to your engine and reduce your BMW’s performance.

Decreased Power

Another sign of ignition coil issues in a BMW is decreased power. If the ignition coils are not functioning properly, they may not provide enough voltage to the spark plugs, which can result in decreased power and acceleration. You may notice that your BMW is sluggish or takes longer to reach highway speeds than usual.

Check Engine Light

A malfunctioning ignition coil can also trigger the check engine light to come on in your BMW. The engine control unit (ECU) in your BMW monitors the performance of the ignition system, and if it detects a problem, it will set a diagnostic trouble code (DTC) and turn on the check engine light. If the check engine light is on, it is important to have your BMW diagnosed by a professional to identify the underlying issue.

Rough Idle

A faulty ignition coil can also cause your BMW to have a rough idle. This can be due to misfires, which can cause your BMW to shake or vibrate while idling. You may also notice that the engine sounds rough or uneven while idling. A rough idle can be a sign of other issues as well, so it is important to have your BMW checked by a professional to determine the cause.

Failed Ignition Coils

Finally, if one or more of the ignition coils fail completely, your BMW may not start at all. This is because the ignition coils provide the spark that ignites the fuel in the engine, and if they are not functioning, your BMW will not start. If your BMW is not starting or is experiencing difficulty starting, it is important to have it checked by a professional to identify the cause.
