F10 M5 CIC Uniti Fan Constantly On

[Longun]

I've got an issue with battery drain and I think it might be the CIC unit fan constantly running. If I get in the car and lock the doors I can hear a fan in the dash continue to run.

I've had a search and it appears this isn't a replaceable part but before I shell out on a replacement unit I wanted to confirm its that part.

Anyone know which fuse is the best one to pull to shutdown CIC? I've had a google and I think fuse 4 in the glovebox will do it but want to be sure as I think there are a few fuses related to the iDrive.

Cheers, Joe
