My horn keeps going off on it's own, even if the car is just stood. It stops if you press the horn a couple of times though. It's got an RS4 spoke on. I've taken the centre out and tested it and it seemed to be sticking on. As far as i can tell after pulling it apart, stretching the spring a bit and retesting it, its stopped doing it.

I've also disconnected the horns but now whenever i try to put it back together i still have the same problem as soon as the plug touches the terminal on the horn, regardless of whether the switch is in or not.

Any ideas?

 

Sorted, traced it back to the terminal in the wheel. It's not insulated so it was touching the wheel itself.
