Recently my 2001 A170 CDI has developed a new noise. Whenever the drivers or front passenger door is opened, I can hear a distinct whirring noise, sounds like an electrical motor running, somewhere in the headlining towards the back of the car. It runs for about 5/6 seconds, then changes to a higher pitched whirring for another 5/6 seconds, then stops. This is all before the key's gone in the ignition, all I'm doing is opening the door. It doesn't do it when the rear doors or the boot are opened, just the front doors.
Any ideas folks?

If anyone's interested, it was the vacuum pump for the central locking. One of the tubes had come undone from the connector.
