Hi All Thanks to all of you for your quick responses. To answer all your suggestions, Firstly the radio is not on so it cant be that. secondly the sound is within the front of the cockpit and it doesn't sound like the sensors for parking and it only happens when im stationary and i leave it in the drive position if i move it out of D into the park it stops and when i put it back into drive and move away from the junction it stops. The other thing that occurred to me was a few days before this started i did set up mine and my wife's driving seat positions but i'm probably grabbing at straws but i thought id mention it, and to finish i diden't know that you could switch off the sensors i must have missed that in the book, so how is that done. Thanks for all you help. Dave
