I guess you are hearing a grinding noise from something in the rest of the drivetrain. Maybe a worn bearing or something touching because of a worn bushing. So something that gets amplified in RWD mode, but is already there anyway.
This needs to be checked by mechanic directly at car.

Thanks for the reply.
Finding a good mechanic is a bit tricky here (I'm near Padova in Italy). Official dealer will just suggest to replace everything, as they always do. I'm thinking to look for a good BMW specific workshop in Austria or even in Munich. Any suggestions welcomed.
There is another noise, high tone, coming only in AWD mode, at speed between 120-160km/h and with throttle on. This seems to be front diff. But this is not linked to xDelete anyway.
