Cant remember the exact figures but dont take it above something like 3000rpm until the car has done 1200 miles. Ignore it if you like, but BMW obviously recommend it for a reason.

Page 168 in the American manual for F31.

There is also need to run in the tyres for 200 miles, clutch for 300 miles.

If you do not let clutch bed in, you do run a high risk of juddering with gears.

The engine allows you 3500 rpm and 93 mph (for diesel).

Can't see why you would need to exceed most of that day to day driving tbh.
Especially in an auto diesel.
