VW Check Engine Light Diagnosis Service

Garnet Volkswagen Explains the Purpose of the Check Engine Light in Your VW

When the check engine light becomes illuminated on your Volkswagen's dashboard, it indicates that the diagnostic system has identified a potential problem. The light is typically yellow or orange and shows the image of an engine. This is not to be confused with your maintenance light, which a service shop typically sets to remind you that routine maintenance is due. Instead, it signals an actual problem, which could be serious.

Unfortunately, there can be many reasons for the light, such as your emissions, fuel, exhaust, or ignition systems. If your light is blinking or flashing, this is a red flag that the issue is severe, and you should bring your vehicle to Garnet Volkswagen as soon as possible. Our certified VW technicians can then retrieve the diagnostic code saved to your system to identify the underlying problem.

Causes of a Check Engine Light Illuminating

As noted above, the check engine light can signify one of many different automotive problems. While it could be as simple as a loose or faulty gas cap, it can also indicate a misfiring engine. In the case of the former, you can simply screw on the gas cap, and if the light disappears within a day or so, you have fixed your problem. In the case of the latter, further driving could cause severe damage to your catalytic converter. This is especially true if your light is blinking, in which case you should pull over immediately and have your vehicle towed to our service department. Other potential causes could include the mass airflow sensor, ignition coils, oxygen sensor, thermostat, spark plugs, fuel injectors, or the emissions purge control valve.
