Thank you for replying to my problem, The continuous noise is there all the time. I even left the car for a day thinking it was something to do with the freezing temperatures. I checked today and I can here it faintly outside the locked car and louder when I open the door. I was first aware of it when I went to use the car on Wednesday morning. I had to drive it with the noise going, but I didn't have to go far. It would be difficult to drive it any further. The noise is not loud it is just high pitched and annoying. You can barely hear it outside. It is not coming from under the bonnet it is inside the car. The noise is there when the key is removed and the noise is there when the engine is running. Hope this helps.

When key out and locked up , most systems are disabled except for the alarm . You do have monitoring of interior which can be switched off to enable the likes of a dog being left in car and not triggering the alarm . It's possible the noise is coming from a sensor inside . You could try switching the passenger compartment monitoring off and see if noise stops . The method of doing so is in the owners h/ book . Might be worth a try and double check doors and boot all fully closed .Also check rear boot partition shelf fully in position .

P.S
If you dont have a h/ book , page 31 onwards
