What does Passat indicator epc light mean?

There are two possibilities for EPC light to be on. First, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring. Also, due to the oil problem, the EPC fault light will also light up. It is recommended to go to the 4s shop for inspection as soon as possible.
