Car doesnt have to be warm. Even if I start it up and rev it (no ratttle) turn the car off and turn it right back on, rev it and it rattles. Im not sure if the SW update or HPFP recall or SW update were done. Took the car in for a checkup @ BMW and everything was fine right after Welt 2.0. Had the car for a year with no issues.
