Howzit Cousins,
Do you hear a "winding" sound everytime you open your door? It seems that the sound is coming from the cd player - its weird because this is the first time I heard this.

BTW, I am also hearing this in my BMW as well.

 

By opening the door you wake the computer system in your car. you cluster and radio are the gateways for all other controllers. i'm sure is normal.

 

Yep, very normal...

 

It's the clock winder. Automatically winds up the clock whenever you open the door.

 

I thought it was the giant key under the boot that was winding, getting ready for a nice long trip.

 

Hmmm..Yes this is very interesting, I was even wondering if it has something to do with my AUX connection since both cars have it.

 

Jeremy1026 is correct - it is the rubberband tensioner!
