Bought a 2019 X5 with the B58C and found out about the plastic oil pump failures after bringing it home. No warranty left so I'm going to update the pump out of pocket as preventative maintenance. Does anyone know a replacement part number for BMW P/N: BMW 11418646454? RealOEM does not show a replacement P/N but the shop techs and I are 99% sure my car has the old oil pump in it. Thanks.

you can call the parts department of your local dealer and they can tell you if that part number has been superseded by a newer part.

My 2019 was built in 12/2018, please update me on the oil pump issue.
Also I thought the engine was B58, please update me on the B58C.

Thank you. I called my dealer and they do not see an old/new part number, only "current" PN so I'm going with that. I stumbled on this post today and it confirmed the new PN: 11418646454.

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...).

$2500-$3000 is a good ballpark for an independent shop to replace the oil pump. Most of the cost is labor. This is much cheaper than paying for a new engine.

Great info. I’ve been seeing an increase of posts regarding this issue. I crossed referenced the new part number in realoem.com with my vin and thankfully mine has the new one!

Thank you very much for the info! My car is 09/2019 and I have the same issues: failure to test the oil level measurement at 17-18% under any circumstances.
Also, I get the following error codes:
1C0101 - Engine oil pressure control, plausibility static: pressure too high (permanent error even after I changed the oil pressure sensor)
1C2001 - Engine oil pump: pressure too high (even if i delete the error code, it appears again after a few miles)
Idle pressure: 40-46psi
Full throttle: up to 100-105psi
