If it were me and I had an M5/M6 past 50,000 miles, I would just go ahead and do a rod bearing change with the ones that Troy Jeup or Steve Dinan uses on his Carbahn motors.
This will most likely ensure greater peace of mind for owners. The fact is that the S63tu still faces the same engineering design flaw as the S85 motors, BMW really doesn't care to build these engines with better reliability in mind, they want you to buy a new M5 when your warranty is up on your old M5. And I'm pretty sure that BMW is still using the same rod bearings from the S63tu F10 M5 in the S63tu4 in the F90 M5. The F90's suffer the same fates in a few years time as well.

Agree 100% and that is unacceptable from such a major player in the car industry worldwide ...
