What does the EPC warning light mean on a Volkswagen?

My girlfriend just phoned me and said there's a warning light that has just come up on her dash that says EPC, she has a Volkswagen Fox.





Any ideas what this could be?|||EPC actually stands for Electronic Power Control (Straight from the VW workshop manual)





It refers to the drive-by-wire system and any faults with the throttle pedal, throttle body, traction control, cruise control, even the MAF will on occasion trigger the light.





It's also known for a stuck brake light switch to do this. Some brake light switches have two pairs of contacts in them, one for the engine and one for the brake lights.





If changing the brake light switch doesn't cure it then you will need to get a VAGCOM scan of the engine controller.|||'Electric Potentiometer Control' . Try switching of the engine for a while then back on again. If this fails, dont bother messing around and get it down the VW garage to be plugged in.|||Engine management system is "sick" and needs to be plugged into a VW computer to be diagnosed.
