What Does the Check Engine Light Mean?

As you drive, your VW model’s ECU (engine control unit) monitors the engine to ensure everything is working the way it should be. If the ECU gets readings that indicate something may be wrong, it stores the reading as a code indicating which system or component had the problem. In addition, it turns on the check engine light. When you see this light, it simply means something is amiss in the engine. When you head to North Penn Volkswagen for a check engine light diagnostic service, our technicians will hook your VW up to a code reader. This code reader will be able to understand the code stored in the ECU, so we will know what part of your VW needs attention.

What Should I Do If the Check Engine Light Comes On?

If the check engine light is solid, you don’t need to panic. This generally means that there’s no immediate emergency requiring you to pull over, so you can keep going to your destination. Once you arrive, check the gas cap; often, a loose or cracked gas cap will be the cause of the check engine light coming on. If that didn’t solve the problem, it’s time to make an appointment at North Penn Volkswagen. Failing to do so might mean that your VW’s emissions, fuel efficiency, and performance will be affected.

If the check engine light is flashing, it usually means that the engine is misfiring. In cases like these, you should pull over as soon as you can safely do so and turn off the engine. A misfiring engine can destroy your catalytic converter, which is a very expensive component to replace.
