EDIT: The shop replacing my oil pump conformed the impeller and its veins are metal, it's the housing surrounding it that is plastic and can disintegrate, causing loss of oil pressure. From linked reddit post:
2019 X5's with the B58 engine have oil pumps with plastic veins and a plastic cover on them. These proved to be ticking time bombs as shown in the posts below. In 2020 models BMW quietly switched all B58 engines to the all-metal oil pump that was used in M car engines. If your 2019 has NOT had the new oil pump installed, it is advised to do this ASAP to avoid catastrophic engine failure. One way of testing for the plastic oil pump is to get the engine HOT, as in drive it for 25-30 minutes, and do an oil level measurement test in iDrive. If the test fails anytime before reaching 100%, your oil pressure is fluctuating enough for the test to cancel. This fluctuation is from the plastic oil pump. NOTE: The test will be successful if the engine is only warm enough to run the test, giving you a false positive, so do it after running all of your errands, commuting, etc. The new, all-metal oil pump P/N is: 11418646454.
B58C just means it's the 3rd iteration of the B58 (B59A, B58B, B58C...).
