Only a complete Diff box exchange can be done easy by a garage.
Changing the inner LSD part needs a lot of know-how because the Crown wheel is welded, in all the BMW's produced after 2007:

Thanks That's the route I would go is the complete swap/exchange which I could easily do myself.

Edit; Just realized it says Manual Limited Slip Gearing Upgrades, Does that mean for manual trans only??
