Common Causes of Flashing Check Engine Lights

When your VW check engine light is flashing, it indicates that your vehicle has a misfire. The most common causes of this issue are spark plugs, oxygen sensors, catalytic converters, mass air flow sensors, ignition coils and gas caps. It’s important to properly diagnose the problem in order to determine what part needs to be replaced or repaired.

Diagnosing a Flashing Check Engine Light

In order to diagnose the problem with your VW check engine light flashing, you first need to check for any stored codes with a scanner tool. This will give you an indication of what component is causing the issue. After that, you’ll need to visually inspect all of the components associated with the code. If none of these steps reveal any problems then you’ll need to perform a compression test on your vehicle’s engine in order to narrow down the cause of the flashing check engine light.

When to See a Professional Mechanic?

Complex diagnoses such as these require specialized knowledge and experience that most people don’t have access to at home.
