In BimmerLink oil psi was 32-35 at idle, 50-70 part throttle, and 90+ on a hard pull. I’ve gotten the message that engine oil is unknown each time I start the car. Testing for oil level fails each and every time. Picked up a new oil pump from FCP Euro for $550.
If the car is has a tune on it, the tuner could have changed the target oil pressure as I've been told.In BimmerLink oil psi was 32-35 at idle, 50-70 part throttle, and 90+ on a hard pull.

I'm very hesitant to drive the car until the pump is replaced. Someone also recommended to replace the oil sensor as well in the pan. This B58 oil pump video came out a few days ago and explained that the springs are different on the updated oil pump in addition to the plastic being replaced.
If you account for ambient pressure, those pressures that @MacAllan30 posted are within spec except for WOT which is about 10psi higher but nothing to really worry about.
If you want no risk, then that'd probably be a safe choice. I like to roll the dice on stuff and just kept driving the car and taking it easy though and nothing happened for me other than the code on pulls and occasional high oil pressure in light throttle. razorlab has a chart that can provide more insight too if the values you gave doesn't take into account ambient pressure.

He is in DFW so approx 600ft = 14.4 psi
35 at idle - 14.4 = 20.6
50-70 part throttle - 14.4 = 35.6-55.6
90 at WOT - 14.4 = 75.6
! I stand corrected then.
FCP EURO had it for $520Well, I finally did this job on my 2021 (build date 07/20).
Not because I was having any issues, but after finding out about the potential problems I couldn't drive without stressing about it
You can see that mine indeed had the plastic adjusting ring, but it is not broken. From what I seem to gather this is more of a cold-weather problem? This is the first oil pump sold (through the Toyota network) in my entire region here in Texas.
Here is the part # for the new pump, which did have the steel adjusting ring. It cost me $720 from my dealership, and I had to wait a couple weeks for it. The local BMW dealership wanted over $900 for it.
It wasn't a terrible job to do, and I think it could be DIY-friendly, but the biggest problem I ran into as someone who usually only works on Toyota vehicles, is that I didn't have a lot of the proper tools. I also "torqued-to-yeilded" more fasteners for this job than I have in probably the last 5 years. It also took me a minute to get used to the repair instructions that were most definitely written in BMW.
Dropping the subframe requires the replacement of a substantial amount of one-time use fasteners, a couple of which, due to my inexperience on this platform, I missed in the repair instructions and failed to order, so I will have to do that at a later date.... or just wait and see if my control arms fall out.
Over all I spent over $1000 on parts for this job and it took me about 12 hours. Now that I know what I am doing, I can see how this is a 6.5-ish hour warranty job.
Per the request of another forum member, I did film most of it, so I will be eventually publishing a DIY tutorial for this job on my YouTube channel, ... but it might be a bit of a hot mess, since this was my first time attempting this repair, and there were so many steps that BMW wants you to take, that in hindsight I would have skipped and saved myself a ton of time.
Sounds right!
Hell yeah! Thanks so much for the inspiration; I wouldn't have made it without your request and kind words since I had literally no clue what I was doing.@Faye saw your video pop up first thing when I checked my YT subscription feed this morning and immediately jumped back to this thread to comment. Thank you so much for creating this, I am sure it will help the B58 community tremendously. I’ll be watching the video a bit later this morning!
