Attached is the M850i maintenance PDF I will be using to track and document all routine maintenance I will be doing to my M850i. It is based on BMW 8 series maintenance intervals recommend and used by USA dealers with lots of extra preventative maintenance.
The extras are based on 20 years of maintenance and mechanic experience. Interestingly, for the M850i, the transmission service at 50k is not recommended by BMW, nor is the transfer or front and rear diff service, all of these are “lifetime” fill. The manufacture of the transmission ZF recommends fluid exchange and filter replacement at 50K. There is no such thing as a lifetime fluid.
I hope this helps one of your guys or gals out.

Lifetime usually means the lifetime of the warranty 😏
