Hi, after bit more help please. My A3 Tdi Glow Plug Light wont go off when i go to start the car so the car wont start at all. I have to turn the keys back off then on again to try and get the light off sometimes taking upto 5 goes before the light finally goes off and can finally start the car. Anybody had any similar problems or ideas as what it could be causing the problem? Thanks.
