Hi guys and gals,

I am getting a wwwiiiiiiizzzzzZZZZz noise about once every minute when the car is either sat with the ignition on and the engine off, or when the engine is on.

I suspect it may be climate contorl related? (as I know most climate systems have a little far to draw air in to check quality/temperature) but in my past experience most claimte fans run constantly. This noise lasts about 2 seconds and happens evey minute.

Anyone any ideas?

Thanks in advance for your help

Do you have a disc in the COMAND? I noticed this as I have the nav disc in permanently and this gets spun every 60sec or so
