2013F10 wroteMy 2019 was built in 12/2018, please update me on the oil pump issue.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.
Also I thought the engine was B58, please update me on the B58C.
gfeiner97 wroteThank 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11418646454.you can call the parts department of your local dealer and they can tell you if that part number has been superseded by a newer part.

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...).

I read somewhere that its around 2500.
Bking60 wrote$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.Anyone had this done out of pocket? What all did they eff up?

2013F10 wroteThank 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.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.
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
markslc1 wroteCan you tell me how you did this?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!
I have this vin nr. do i have the old or the new part?

badsha wroteI input my vin into realoem then searched for the oil pump. The parts listing showed the new part number without any notes about superseding an older number.Can you tell me how you did this?

Could you please confirm: pn.11418646454 was upgraded to the same pn. 11418646454 With all metal internals without new part number?
Car is G06, production date 06.Nov.2019.
Dian4o wrotePhysically?? Probably not practical at all. By the time you get to see the pump. You may as well replace it. The whole job is labor intensive, parts are inexpensive.Is there a way to check physically if the oil pump is old one?

I did reach out to BMW NA for support, but received none. CarMax has more honor and pride in regard to what they sold you than the manufacturer who made it. To me, a lover of motorsport and of BMW, this is terribly dissapointing. Still, good for CarMax- and I'm happy for you, too. Enjoy the X5; it's a great car.
JimWashington wroteCould you please elaborate on what you think BMW did to hide this issue? Thank youBMW is clearly aware of this problem (they redesigned the part for future B58 engines to avoid failure), and should remedy it through compensation or recall. They have now issued a software update which I think could be designed to hide the problem. I had symptoms of failure and replaced the oil pump. Upon opening it up, it did have fractured pieces inside, and the housing was brittle; it was failing. If I had gotten the software update, I'd still have had fractured pieces inside the pump and it would have continued to disintegrate.
