Why is My Check Engine Light On?

Because it monitors a variety of different vehicle diagnostics, your check engine light being on could mean a variety of different things. Here’s what to do:

What Components Should I Inspect If My VW Check Engine Light Is On?

Volkswagen vehicles are precision machines, designed by German engineers to deliver impeccable performance day-in and day-out. For this reason, it’s important to carry out all repairs using genuine OEM VW parts. The best way to solve your check engine light problems is to take it into a Chicago-area service center for inspection. However, we wouldn’t blame anyone for wanting to know what to expect. Although each of the common causes listed above could cause your check engine light to light up, you might want to pay special attention to the following parts and components:

Your vehicle’s emission system uses a catalytic converter in order to transform carbon monoxide into carbon dioxide. If it isn’t functioning properly, you’re probably not at risk for an immediate breakdown. However, you will notice reduced performance for as long as you go without fixing the problem.
