You're right idk why I wrote vacuum pump when I meant brake booster. Our oil and vacuum pumps are the same part. The recall affected both the oil/vacuum pump and brake booster is what I meant to say.
Toyota thought the brake booster was at fault but it was the oil/vacuum pump. I'll edit my post
...and I appreciate it. The failure mode may not have been the same, but my head is in a place where I'm just baseline suspicious of all B58TU oilpumps.
Trying to imagine what happened: It's also possible that some of the polymer pump supply bled into the next model year's parts pool, which...
The vacuum pump and oilpump are both located "in a shared housing" - I don't think you can replace one without the replacing the other...

...vacuum pump and my problem still persisted. They took the L and apologized and gave me a refund on the vacuum pump and I had to replace the oilpump at the end of the day. The recall definitely damaged both parts. My vacuum pump's valve was also damaged and they replaced that for free for me...
I see no proof he even had the polymer pump. Where's the photos and repair order notes? Pumps can fail for other reasons. I remain skeptical in the other direction.
I know you know your shit, so I'm not going to argue with you. I just gotta see specific evidence to be swayed.
I remain unconvinced that this issue is solved in post-20 B58TU engines. Here is a '21 Supra with a failed oilpump replaced under warranty.

In what context? Only the older ones had the breakable plastic piece in the oilpump, and if any MKVs were potentially affected (in the US), it was the earliest MY 2020s. Otherwise we all have the updated pump, and nothing to worry about.
This recall and potential issue ONLY affected the...
...damage the pump.
I have a 2020 model, and I’ve already had the recall addressed. Since then, I haven’t experienced any issues with oilpump pressure or oil level readings. My car has gone through six oil changes using Liquimoly 0W20 and has recently switched to 5W30. It has never burned oil...
I have a lift and tools etc. it’ll just be my first “BMW” I’ll ever be working on. There also doesn’t seem to be a write up anywhere I can reference to do it myself. I just don’t wanna go to the dealer and they brick my ecu. I’ve heard of cases where people tell them not to plug in and they get...
Unless your garage is well equiped I don't think you'd even be able to change your oilpump by yourself. It requires the subframe to be dropped. Just had my oilpump replaced a couple of weeks ago. $590 for the pump and like a grand in labor fees.
You can try to bring your car to the...
I did that recall and it’s been well over a year since it was done. Just unsure where to go from here. I don’t want to do the oilpump myself and then it’s doesn’t solve the issue. Then I’m paying for a whole motor
If this is the saga I recall, it wasn’t the dealership that didn’t tighten your oil filter. The filter was an aftermarket with an orange o-ring which pretty definitively proved the dealership was not where that oil change was performed. The factory o-ring used by Toyota and BMW is black.
This gives me PTSD because when I got that message on my car, my engine blew within minutes lmfao. Turns out the dealership didn't torque down the oil filter in the housing and I dumped 7 liters of oil in the span on minutes. Then my car shut down. Dealership denied responsibility. They quoted...
I suspect your oilpump has failed.
This would be covered under warranty, and (except in very specific circumstances that are probably not applicable to you) would not be caused by the tune.
You can either let the dealer handle this, or do a DIY oilpump replacement. I haven't checked in a...

I recieved the oil feed line restrictor, put it in, haven’t seen smoke since. The oil level was not dropping so my issue was quite minor. I’ll keep an eye on it though
Shawn said they did change the internal design of the turbo to mitigate the issue, so you might not have the issue if you...
Very interested to see where you get to with the oil issue. Looking at a similar setup down here in NZ, need to be on 98 as well - no pump E85. Thankfully a bit cooler ambient temps though :)
Hey guys,
looking for some advice or if anybody has any experience with their lower coolant reservoir looking a lot more murky and brown than the upper reservoir for their coolant. It’s 21 3.0 automatic (obviously), 32k miles. I’m led to believe the upper is intercooler and lower is engine and...
Did you notice it more when you had the A/C running? I'll need to drive my car a couple more times to pinpoint the sound before taking it to the dealer but I could almost swear it was coming from around the area where the alternator/compressor/drive belt live. I'll try to see if my car can...
