Ongoing maintenance and auto care are essential for cars like BMW that were designed with a strict set of standards. Not only can it ensure your car’s performance for its lifetime, but it can also prevent the common issues associated with the brand, such as premature ignition coil failure. In this article, we’ll go over the basic warning signs of failing ignition coils and other tips on how to avoid failure all together.
Look for Warning Signs
When attempting to avoid ignition coil failure in your BMW, it is crucial to pay close attention to how your Bimmer behaves at any given moment. Any warning signs should be addressed with immediacy—as the longer you wait to repair the issue, the more issues will arise due to the failure of the ignition coils. Engine damage due to faulty ignition coils is common, and therefore being aware of the typical warning signs in your own BMW can spare you significant money in repairs later on. These are the most common warning signs associated with ignition coil failure:
Reduced Fuel Efficiency
A concerning sign of vehicle malfunction and diminished performance, reduced fuel efficiency can point toward an array of issues your BMW might be experiencing—even simultaneously. If you begin to notice your car is using up a lot more fuel than usual, it could be compensating for failing ignition coils.
Engine Stalling or Misfiring
For any driver, let alone someone who comes to trust and rely on a BMW’s performance standards, engine stalling or misfiring are highly concerning symptoms to encounter. It is typical for failing ignition coils to cause disruptions in the combustion and ignition processes, creating these severe symptoms of compromised engine performance.
In order for your BMW to sufficiently start its engine, the ignition coils must be performing properly. When the ignition coils aren’t functioning well, the spark plugs can’t receive the right amount of energy, leaving your Bimmer at a serious disadvantage upon initial ignition.
If an ignition coil begins to overheat, this may point toward another rooted issue to address—i.e. what’s causing the overheating in the first place? However, overheating coils themselves will create conditions under which they cannot conduct the proper amount of energy for their intended purpose.
It’s normal for an engine to vibrate slightly under normal operating conditions; however, if your engine is vibrating more than usual, it could be causing internal damages to take place, including ignition coil failure over time. Depending on the severity of the vibration, other engine components could become damaged, so it’s critical to address with immediacy and efficiency.
Spark Plug Condition
Over time it is normal for parts to begin to wear out and require replacement. In BMW cars it is essential to conduct frequent inspections of spark plugs; when the spark plugs become worn, it can cause the ignition coils to overwork themselves, causing added stress to the coils and leading to premature failure.
Other Ways to Avoid Ignition Coil Failure
The best ways to avoid ignition coil failure, besides being aware of the common symptoms after something has gone wrong, are good old-fashioned maintenance and repair work. Following your designated BMW maintenance plan designed by the manufacturer will usually prepare your car well for the road ahead; however, it is always recommended to consult with a trained BMW specialist to detect any preemptive signs of failure.
