Over the last couple of months I have been getting a noise when I start the car. It only happens when it's cold / damp (been left overnight). It is a whining noise which sounds almost like a belt slipping and lasts for about 5 seconds. There are no other obvious problems - drives fine, everything else working normally.
Any ideas?
Also, when I have looked under the bonnet, I notice that the radiator fans are working, on start up and still going after a half hour journey. This doesn't sound right.
