Service bulletin B340420
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
PROCUT BRAKE LATHE UPGRADE: On certain newer BMW vehicles (e.g. G12 M760i G14 G15) the technician cannot perform brake rotor resurfacing using the ProCut PFM9.2 or X9 brake lathe. The lathe gearbox housing contacts the largediameter rotor preventing proper setup. New models introduced with brake rotors larger than 374 mm (approx. 14.75") require new equipment for service.
