Check Engine Light Diagnosis

What Can Cause the Check Engine Light in Your Volkswagen Vehicle?

Determining the cause of your check engine light can be difficult without the specialized equipment that we have at Volkswagen of Winchester. But, if you bring your vehicle in, we can pull the codes and tell you what the issue is. Sometimes it is simple, like a loose gas cap or some bad gasoline in the tank. Other potential causes can include the mass airflow sensor, oxygen sensor, emissions purge control valve, ignition coils, fuel injectors, or spark plugs. Whatever the cause, don’t waste precious time. Contact us at Volkswagen of Winchester as soon as possible.

What Should You Do When Your Check Engine Light Comes On?

When your check engine light comes on in a solid, unblinking state, check your gas cap to make sure it is screwed on tight. If that is the issue, the light will go off within a day or two. If it does not, then reach out to our certified technicians at Volkswagen of Winchester to schedule an appointment online or over the phone. However, if your check engine light is blinking, then pull over immediately or have the vehicle towed to our service department, as this indicates serious issues, like an engine misfiring that can permanently damage your vehicle’s components.
