Car was driving fine after a dealer oil change, then on a long road trip I get the error message "low oil pressure" stop car and take back to a service center. BMW dealership in San Rafael CA says that BMW NA told them to remove the oil pump and inspect it, but that it may not solve the issue. My car has a [XXX] production date according to the VIN. There are many other BMW M340 owners that have had to get their oil pumps replaced for the 2020 model year, same as mine. The new oil pump has a different design, metal impeller vs. plastic on the old one. The repair cost is quoted by the dealer as $6k + the parts, and they still wont know if it fixes the issue.

Oil pump in earlier models are known to fail prematurely due to plastic internals. There is a revised oil pump that has all metal internals but those have early model vehicles with same engine have received oil pumps that fail and can be catastrophic while driving and causing injury if vehicle fails and causes accident.

The engine oil pump has failed. The part is available for inspection. The failed oil pump causes the engine to blow up, leaving oil and coolant behind on the road as hazards and causing our vehicle violently spin out on the road. The problem has been reproduced multiple times and claimed by bmw dealerships to be faulty on multiple occasions. Upon further research, it has affected 80% of the 2019 and 2020 g series chassis vehicles with the B58tu engine. BMW has a known problem of failed oil pump. As has my own 2020 bmw m340i. The only warnings we had were the oil not measuring through the interior display, the only way to check it no dip stick, not completing or stopping at 21% with failed measurement. It has first appeared for me at 20k miles, for others as early as 5k miles. The vehicle has not been inspected by police or insurance other than the dealer and local independent shop.
