The EPC light on a Volkswagon Jetta is the Electronic Power Control indicator, which comes on when the vehicle experiences a motor malfunction. The purpose of the EPC light is to alert the driver to engine trouble so that the driver can take steps to avoid further damage to the vehicle.

When the EPC light is on, the vehicle might also be limited in power because the system puts protection methods into place to keep the engine from incurring further damage. When the EPC light comes on in a VW vehicle, owners should seek help from a certified dealer to keep the vehicle in good working order.
