Buzzing

[Reedie]

Can anybody help, when sitting in my x type and no keys in the ignition I can hear a continuous buzzing but have no idea what it can be. Is this a common problem?

this is nothing to worry about, as this is the in cabin "ambient air temperature sensor" if you look at the steering wheel in your car, you should notice a very small vent about 1" square? this is the sensor.  I sometimes blow it through with a can of "air duster" which you use on a computer keyboard,

Thanks David, that's a great help I must admit I was beginning to get worried. I will give your tip of the "air duster" a go.
