What Is the EPC Light?
What does the VW EPC light mean when it shows up on your dashboard? It is a sign that your vehicle is in need of immediate repairs. You should still be able to drive the vehicle, but no more than necessary to get it to a service center.
Alexandria Volkswagen has provided a list of the most common causes for a Volkswagen EPC warning light to become illuminated:
- Throttle pedal or throttle body issues
- Cruise control trouble
- Engine speed sensor error
- Mass airflow sensor error
- Issues with your brake light switch
