FAQs—BMW Ignition Coil
- Since last week, I've been experiencing a couple of problems with my BMW. Sometimes, the engine doesn't start at all. My mechanic told me that it could be due to a worn-out ignition coil. What are other signs to prove this?
If you've experienced difficulty starting your vehicle, there is a possibility that your ignition coil is completely broken. This happens when it can no longer supply enough power to the spark plug. However, aside from this, there are other symptoms that you should be wary of. Misfiring or backfiring is also a sign that your ignition coil is in poor shape. This is due to the excess or unused fuel that seeps through the exhaust system when you have a faulty ignition coil. This can be usually felt when the car reaches higher speeds; you will feel that your car is vibrating and running roughly.
- Lately, I've been wondering why my fuel consumption has been really high. I just replaced my BMW ignition coil with a new one. Is there something wrong with my new part?
Poor fuel economy is an indicator that your ignition coil is already wearing out. When this happens, the coil can cause excess fuel to seep into the car's exhaust system, wasting large amounts of gasoline every time you set on for a drive. You might want to check if your new ignition coil is compatible to your vehicle since it can cause your fuel to empty out when your car needs to compensate for the reduced power of the spark plug. Check your ignition coil especially if you've also been experiencing stalling or trouble starting your vehicle.
- My car keeps on stalling and backfiring so I brought it to the mechanic. The diagnosis was a worn-out ignition coil. Should I replace my BMW ignition coil with a new one immediately? What are the implications if I keep it?
Neglecting an issue like a bad ignition coil can do more harm than good to your vehicle. Aside from the usual symptoms that it can cause, keeping a worn-out coil can inflict serious damage to your exhaust, which can result in unnecessary and costly repairs. You know that it is getting worse if you've already seen a black smoke being emitted from your exhaust or detect a smell of gasoline from the ignition area.
- I've been replacing my BMW ignition coil almost twice a year because it easily wears out. What should I do to keep it from succumbing to premature wear?
A simple way to keep your ignition coil from wearing out is to ensure that your spark plugs are all in good condition. If your spark plugs are worn out, your ignition coil tends to operate at a much higher output. But when you keep your spark plugs intact, it will also contribute to the condition of your ignition coil. All you need to do is to perform regular maintenance for your spark plugs and other components. Take time to check these parts before you drive your car.
