I've changed the fuel filter, vacuum lines, fuel pump and checked all the fuses nothing has done the trick. Does anyone know where the relays are located for the fuel pump. I am very new to the Audi world so really know nothing about this car but I couldn't pass up the deal I got on it now I think I know why. Hahaha also I was reading up on a high pressure fuel pump in these cars where is this located if anybody knows. Any help would be fantastic cause I am at a loss as to what the hell is going on with this car. Thanks
