  1. “Engine Oil Pressure Too Low”

    ...the low oil pressure warning come on and was unable to check oil level in the Toyota oil settings. Found this thread and thought it was my oil pump. BM3 oil pressures are normal. I'm out of warranty with miles and mods so cost will be on me. Debating if I need to change out the pump as when I...

  2. “Engine Oil Pressure Too Low”

    Not clear on what you are asking. Do you just want to know what OEM oil pressure setpoint is when everything is working correctly? Here you go. It's in hPa to convert to PSI and subtract your ambient pressure depending on how you are logging.

  3. “Engine Oil Pressure Too Low”

    The pump failsafes to high pressure, so if you are seeing abnormally high pressure...

  4. “Engine Oil Pressure Too Low”

    Has anyone seen abnormal pressure measurements in BM3 when the oil pump is damaged but still functional?

  5. “Engine Oil Pressure Too Low”

    Did you do the I level update with or without the updated metal pump? Or did you replace it? Curious if I should get ahead of this as a preventative measure. No issues and works fine. Also don't have the dealer recall DME update. 7/19 build date.

  6. Smoking from exhaust

    Dealers, how to organise the dumbest most costly indirect route to the solution. Phil

  7. Smoking from exhaust

    Update 4-7-25 Oil control valve didn’t fix issue of course. They said they sent all the info over to Toyota and they approved the oil pump. Of course back order no eta but so were the level sensor and control valve lol. So now oil pump is ordered and just waiting for the text to have it...

  8. ANOTHER OIL THREAD (Actual information doe)

    I'd add that beating on the car for extended periods of time. In Southern Cali, this is a recipe for a reckless driving charge. I'd add ..."driving normally, most of the time with occasional brief bursts of speed beyond 100 mph." If your oil temps are spiking beyond 230 or 240°F, then your...

  9. ANOTHER OIL THREAD (Actual information doe)

    I didn't see it posted in this thread but thought this was a good read lots of info summaized in one place, I believe this is from a credible source: https://www.bimmerworld.com/BMW-Engine-Oil/#oilrecs Also see bimmerworlds oil recommendations attached. So the takeaway is if you frequently...

  10. DINANTRONICS X In-line Performance Tuners for the Toyota GR Supra

    Does oil temps rise beyond typical levels? (220 degrees or so) Pump gas octane level in CA maxes out at 91 octane, unfortunately.

  11. Cannot measure oil

    Thanks to this thread and this forum, I had Toyota replace my oil pump under warranty. Had the same symptom of the oil measurement procedure crapping out around 30%, told Toyota that was the issue and that the forums suggested this is a sign of the oil pump failing, took them two weeks to...

  12. Do I need a new motor?

    This is the optimal way to drive on E50 - as the heat generated by the constant load will often burn off any moisture in the oil caused by the phase separation properties of the E50. The guys who run ethanol but only take their car out on the weekends to a car meet or a grocery store are the...

  13. Do I need a new motor?

    Yea I have a friend that also has a mk5 that said it definitely isn't a common problem. Do you always run close to E50 daily?

  14. Do I need a new motor?

    ...Flex Fuel tune. I don’t baby my car at all. Its sees plenty of wide open driving every chance I get. No problems with mine so hard to say what happened with yours. Maybe detonation or a piston ring broke from a faulty oil pump. The 2-ports have the plastic oil pump that has been problematic...

  15. “Engine Oil Pressure Too Low”

    f series bmws have been using the plastic oil pump adjustment rings forever, including in the m cars. on the supra there are 3 versions: plastic ring, plastic vacuum cover (mahle) plastic ring, metal vacuum cover (omp) metal ring, metal vacuum cover (omp) the middle one is the one with issues

  16. “Engine Oil Pressure Too Low”

    ...it before: According to that info, the revision index 05/06 distinction isn't relevant to our cars. That part is the 11-41-8-646-454 "oil pump" used in things like the 740i and X7. The part that matters to us is the "oil vacuum pump", part numbers 11-41-8-646-453 (bad plastic) and...

  17. “Engine Oil Pressure Too Low”

    Exactly. Yes, exactly. Sorry I didn't share the whole document, I just wanted to keep the dealership and my friend anonymous since I am pretty sure this isn't supposed to be shared for public consumption. But I just cropped the dealer info out.... we need this to keep our cars on the road...

  18. “Engine Oil Pressure Too Low”

    ...information I’ve seen posted here or on the BMW forums thus far. A few thoughts… Is BMW outlining two separate types of oil pumps, one with a vacuum pump (11 41 9 895 359), and one without (11 41 8 646 454 index 06+)? A quick check on a BMW parts website confirms this is likely the case...

  19. “Engine Oil Pressure Too Low”

    Oh good thing that's the case then! Thanks for easing my mind with that. :)

  20. “Engine Oil Pressure Too Low”

    That is to make sure the car has had the brake recall performed (which is a software update). The oil pump is part of that system and the I level before 20-11-500 has not had the software update yet. If you have had the brake recall performed or your I level has been updated (like I did myself)...
