Audi 2005 B7 EPC on, won’t turn off. I lost my car key and had a new one programmed at Audi. Every since I got it back from them the EPC light has been on and won’t turn off. I work at Subaru and they replaced the fuel pump thinking it was that but it still hasn’t turned off. Mechanically ( according to the tech who worked on my car) it is in perfect shape. There’s no reason for the light to be on. I made an Audi appointment but don’t want to have to spend Audi money for a problem I can probably fix at home.
