​Expert European Auto Check Engine Light Diagnostics in Rockville

If you own a luxury European car, SUV, or van, you’re probably all too familiar with the dreaded check engine light. While this may be a common occurrence in other types of automobiles, it’s definitely not something you want to see in your luxury vehicle. You may wonder what are some of the most common reasons your check engine light comes on?

One of the most common reasons is a faulty oxygen sensor. This sensor is responsible for monitoring the air/fuel mixture in your engine, and if it’s not working properly, it can trigger the check engine light.

Another common reason is a loose or dislodged gas cap. If your gas cap isn’t tight enough, it can cause your car to “leak” fuel, which can set off the check engine light.

Also, a dirty air filter can also trigger the check engine light. If your air filter is clogged with dirt and debris, it can restrict the airflow to your engine, causing the check engine light to come on.

While these are some of the most common reasons your check engine light comes on in your European automobile, there could be other issues at play as well. If you’re unsure of what’s causing the problem, it’s always best to bring your car to our certified mechanics for proper diagnosis and repair. At Excluservice, we will inspect your vehicle, quickly inform you of our findings, and advise you on your options of how to proceed.
