Think it's totally fair and reasonable IMO to keep the thread open it still shared some interesting stuff and prompted me to "check the checker" from the Toyota website and have peace of mind :headbang::respect:
Yeap, Toyota called me back and said nothing outstanding either. Mine had a brake something recall done in 2021. She hadn't heard of the oil\vacuum pump recall or any related issues. Close the thread :)
Measure with a scantool rather than iDrive. You get to see a real sensor value instead of an estimate. Also the warning in iDrive does not come on until you are about 1.5 liters down, ~78mm on the sensor readout.
Oilpump was failing causing oil pressure to be low during oil measurement tests. If anyone else has these issues just know your oilpump is failing.
Toyota replaced my oilpump under warranty and now I can measure my oil level whenever I want which is nice.
My oil consumption test “passed”...
For sale is my 2021 Supra w/10,xxx on it and counting. The car is fully unlock on ecutek it’s an early 2021 model and ecu is pre 6/20. Only reason I’m selling it is because I’m pulling the trigger on a m4 comp. Oh yea no liens on the car I own it flat out. Clean & clear title.

Thicker oil isn’t a band-aid. Its a permanent solution. If the car runs better with thicker oil why not switch to it? Its not a bad thing like people make it out to be.

Make sure they change both these parts, insist on it. Would suck to go back and start again because the sensor is bad too.

Maybe I am a bot but I don't see anything that refers to an actual technical bulletin number where bmw/toyota are replacing these under warranty for people only threads of somebody dropping off the car and expecting the dealer to fix it based on x conditions.
really not sure why people are not...
Here is a post referring to a TSB

I don’t get why some Supra owners aren’t bothered by the consumption and instead just band aid fix it with thicker oil…
I was consuming oil with 0w-20, I don't anymore
Does anyone with access to TIS know if something has been posted for this? - A bulletin will take me a long way in just getting a free pump since I won't go to the dealer to let them just monkey on my car
Your oilpump is for sure the culprit. As others have stated they have since upgraded the oilpump and Toyota even adjusted the part number for it. Apparently BMW made an underground recall for it.
For sure get it fixed while you still have warranty.
Did you have consumption issues on...
I am having the same issue right now. My car is at the dealership awaiting word from Toyota and was told today that it will probably be there for more than a week. I am also experiencing parking brake malfunction error while I was driving over the weekend. Very disappointing right now car is. I...
...to me that they were unable to conclude the oil consumption test as the oil measurement system is failing. So they have opted to replace the oilpump and then have me redo the consumption test yet again.
Funny thing is the oil measurement system doesn't even show precise oil levels instead...
This is typically indicative of the oilpump failing unfortunately. B58's have plastic internals that fail in the oilpump which cause issues with the oil level measuring. It's expected to become a recall to the few at BMW that I've talked to about this.
UPDATE: Looks like my oilpump is failing according to Toyota. Coincidentally I got a low oil light saying to add 2 quarts after driving for 1300miles right before I brought it in.
Toyota is saying that they might need to replace the oilpump before they can complete the oil consumption test...
So here is a great visual showing what I mean that water and oil temps influence each other. It's not really summer here yet in the North East but this session was 85* and you can clearly see oil and water temps following the same trend.
...closely. I expect we eventually will see some adapter plates to Separate into a air cooler/ radiator but this could also require a bigger oilpump so probably why you do not see them as that is a much bigger project. Has not really been an issue for the rest of the year when the starting air...
