Not many things exude the level of thrill that comes with owning a high-powered luxury BMW Car.  However, like every other brand, it has its fair share of issues, some signaled by the check engine light. Let’s have a quick look at some of the most likely reasons your check engine light may be triggered:

Check Engine Light Problems

  • Loose Gas Cap

If your BMW’s check engine light comes in, it could be because of something as simple as a loose or damaged gas cap. So, one of the first things to do when you notice the light is to check the fuel cap and ensure it is tightly closed. 

A loose gas cap will result in fuel wastage and may cause fire hazards, so it’s important not to treat it lightly. And if you think your gas cap is damaged, you can come by our auto shop for inspection and repairs/replacements. 

  • Faulty Catalytic Converter

Your BMW’s catalytic converter is designed to convert toxic gases into much safer gases, thereby reducing harmful emissions. A faulty catalytic converter will invariably affect engine performance, increase emissions, and trigger your check engine light. 

Symptoms include sluggish powertrain performance, rotten odor, dark exhaust smoke, and rattling noise. If you notice any of these symptoms, visit our auto repair shop, and let’s have the problem taken care of. A faulty catalytic converter is not a good look on your gorgeous BMW. 

  • Failing Oxygen Sensors

Oxygen sensors ensure proper air-fuel mixture in your car by keeping tabs on the oxygen level in your exhaust gases. If they pick up a fault, your BMW may suffer reduced fuel efficiency and poor engine performance. It may also trigger your check engine light. 

Other signs of a faulty oxygen sensor include rough idling, engine misfiring, rotten smell, black smoke from the exhaust, etc. If you notice a sudden drop in your car’s engine performance and other odd symptoms, visit our auto shop for proper diagnostics and repairs. 

  • Defective Spark Plugs

Spark plugs are key to your BMW’s combustion. They are responsible for firing a spark to ignite the fuel, generating the required energy to fire up the pistons and move your car.

When the spark plugs fail, you will likely experience engine misfires, reduced fuel efficiency, and a drop in general performance. A defective spark plug may also trigger your BMW’s check engine light.
