Differential maintenance for M340i/M440i

Good morning,

I'm curious, coming from a clutch based LSD vehicle before (Mustang), what the expected lifetime is for the clutches in the m-diff, and expected servicing or maintenance thereof, if any. Thanks!

Link above for transmission - change your differential fluid at the same time.

So no changing of clutch disks in the differential? I thought clutch based differentials wore out?

Or does the m340i m diff not use a clutch pak?
