Help!! First ignition 'click' starts car?!?!

Well this is a rather strange issue, I've just finished fitted my ashtray delete on my 3dr A3 and turned the ignition round to the first click to check the air con all works correctly after being disconnected and the car started?! Thought it might just have been something I did so I took the key out and slowly turned it and once again as soon as it reached the first click the car fired up! What on earth could I have done accidentally to cause this? I also had my pioneer radio out and unplugged which was plugged back in but apart from that and the air con unit I've touched nothing.

Any help would be appreciated as I'm too scared to drive the car incase I've done something seriously wrong!

Problem solved, not sure what It was I did that fixed it (or caused it for that matter) but at least its gone!
