What is the EPC light for on a GTi Mark 5 Is it save to drive?

EPC stands for Electronic Power Control. It is a warning light on the dashboard of your Volkswagen GTI that indicates a problem with the engine's electronic control system. The EPC light is designed to alert you to a potential problem with your car's engine or transmission. It typically illuminates when there is an issue with the car's electronic throttle control, fuel injection, or ignition systems.

It is not generally considered safe to drive a car with the EPC light on. If the light comes on while you're driving, it's important to pull over and turn off the engine immediately. Continuing to drive with the EPC light on could cause further damage to your car.

Here are some of the possible causes of the EPC light coming on:

1. Faulty throttle position sensor

*2.** Faulty mass air flow sensor

*3.** Faulty oxygen sensor

*4.** Faulty ignition coil

*5.** Faulty fuel injector

*6.** Faulty Engine Control Unit (ECU)

If you're experiencing this problem, it's important to have your car diagnosed by a qualified mechanic as soon as possible. They'll be able to identify the cause of the problem and perform the necessary repairs.

In most cases, the EPC light can be turned off by a simple reset of the car's computer. In some cases, however, the light will remain on even after the problem has been fixed. If this is the case, you may need to have the car's computer reprogrammed.
