Hi guy's am abit stuck had my audi plugged in and it was showing a heater plug fault, so iv jumped the gun an fitted 6 new heater plugs thinking it was them. Now iv checked the leads with a test lamp when ignitions on and nothing. Think there isnt power getting to them. Where abouts is the location of the relay on a5 3.0tdi the cars a 2007 capa engine. Iv been having dpf problems and bin told if theres no heater plugs the car wont regen. So need to fix it, sharpish. Thanks anyway help would be much appreciated
