BMW ignition coils can last upward of 140,000 miles with proper care, but eventually, they will need to be replaced. Depending on your driving habits, you may need to change your ignition coils every 50,000 miles or sooner. Coils that are not functioning properly can cause engine misfires and other performance issues.
If you are not sure whether it is time for a new set of coils, have your mechanic take a look. They will be able to test the coils for proper function and let you know if it is time for a replacement. Ignition coil failure can lead to more serious engine problems, so it is always best to stay on top of this maintenance item.
When you do need to replace your BMW ignition coils, be sure to use OEM parts. There are many knock-off ignition coils available on the market, but they will not fit as easily and some may cause other problems in your engine.
Your BMW dealer is familiar with your vehicle’s needs and can help you determine how often to change ignition coils for optimal performance. It is also a good idea to have your coils inspected every 30,000 miles or so to ensure they are in good condition. By following these guidelines, you can keep your BMW running like new for years to come.
