Hi, I bought a audi a2 and the previous owner had put in a new headunit. Trouble is it has a mind of its own and turns off and on when it wants. So i chaned the headunit and seemed to be ok, but it now doing it again, but seems to be when i the do stuff like turn lights on or push the petrol pump or even the indicators. Does anyone know what it could be?:blackrs4:

When you pull the headunit out, is the original ISO connector used to fit the new head unit, or is it bare wires? This would give you an indication of the state of wiring behind the dash.
