Q:

What is an EPC light on Volkswagen?

A:

The EPC light on a Volkswagen stands for Electronic Power Control, and it is used to indicate problems in the engine. Ideally, it refers to the drive-by-wire system that prevents a car from skidding and spinning on slick surfaces.

The EPC light system warns drivers by sending codes to the dashboard. The codes indicate the system of the car facing a problem, but not a specific problem in the system. It indicates any faults with the traction control, throttle pedal, cruise control-, and throttle body. It can also show malfunctions and defects of the EPC. An additional sensor can be installed to find what specific problem a Volkswagen is facing when the EPC codes are displayed.
