  1. Oil pump tsb?

    Good shit, bro’. Glad you’re getting it taking care of in warranty.

  2. Oil pump tsb?

    ...the first dealer refused to do anything further "without codes"), they were able to duplicate the bad pressure numbers obtained by my Indie BMW shop (and confirmed by BMW Tech Support as needing a new oil pump IF it was a Z4 - hah!) and it has been approved for a warranty oil pump replacement.

  3. Race Tracking Your Supra - Information exchange

    I haven't yet, but I am a sample of one. ;) I do have a 2020 though so it's probably just a matter of when, even if I didn't increase oil pressure. If/when my pump fails, I will probably swap it with a ZTK pump. There are two tables that set the max/min oil pressure that will trigger an error...

  4. Race Tracking Your Supra - Information exchange

    It shouldn't really fluctuate much. PID is there for it to hit target, just like boost control. There is also an offset table that is used to up pressure for Vanos depending on load and rpm. OEM it's set to increase oil pressure around 3000-4500rpm When I defined the Oil Pressure Setpoint I...

  5. Race Tracking Your Supra - Information exchange

    Thank you for posting the PID tables. I didn’t realize setpoint was in absolute- I’m surprised WOT is that low for stock parameters. I noticed that my oil pressure targets varied in my logs at similar RPM’s, so I figured that targets were dynamic- I just wasn’t sure what exactly influenced it...

  6. Updated oil pump?

    ...the warranty period the manufacturer can't just fob you off if it fails far earlier than what is considered a reasonable life. So the Supra oil pump falls into this category. An oil pump should reasonably be expected to last the life of the engine and if it fails before that then it's not...

  7. Updated oil pump?

    I am frequently on the G20 forums and I haven’t seen anything notable yet. Forums represent a small sample size of owners though, and I imagine unless BMW extends the warranty it will be situational. My warranty just ended, and if the oil pump died tomorrow I wouldn’t attempt bringing it to Toyota.

  8. Race Tracking Your Supra - Information exchange

    are there any corrective tables that influence oil pressure? I’ve always had oil pressure issues both with/without the Verus oil cooler and just never manage to hit oil pressure targets once oil temperature hits 260F. Currently experimenting with 5w50 to see if this helps.

  9. Updated oil pump?

    True. I should've phrased that better. Still, do we know how BMW is dealing with the B58TUs plastic oil pump issue for those out of warranty? I haven't had a chance yet to dig around the BMW forums or reddit to find out.

  10. Race Tracking Your Supra - Information exchange

    The oil pump is electronically tied into the DME. It has pressure set point tables and full PID control.

  11. Race Tracking Your Supra - Information exchange

    Have you actually changed the oil pump or just running a thicker viscosity oil? Are you trying to avoid deviations +-3 degrees or want it tighter?

  12. Updated oil pump?

    My guess is they don't know how to run the check. They probably don't know it's supposed to go to 100%. They run it, it stops at 23% or whatever (mine was 16%) and then it says Oil Level OK, so they think it's ok. Most Toyota dealerships are clueless about this car, even 5 years later. If you...

  13. Updated oil pump?

    Just an update so far. One dealership in concord didn’t want to take the car because it’s too low. The other one, one city over, had the car for two days. The first day they just checked with the car running and were able to run the oil. You can read the oil level when the engine has been...

  14. Updated oil pump?

    I would go through your dealer and ask for goodwill warranty coverage first. While it’s a very small percentage that are failing there are enough that Toyota knows there’s at least a small issue going on. There’s also the fact that BMW subsequently replaced the plastic piece with metal which...

  15. Updated oil pump?

    Hey all. unfortunately my problem with the oil pump just started, I’m 1.5 months out of the 5 year 60k mile warranty. FML My car has barely 20k miles. It’s not gonna be cheap I know. Does anyone know a place in the Bay Area that is not a dealer that can replace the pump? The dealer is gonna be...

  16. SUPRA DIFF BRACE

    They have had that since the inception of the GT4 Supra. The additional cooling on the Evo2 is an inline "chillcooler" in the charge pipe:

  17. Oil Pump Control Valve before Oil Pump Warranty?

    This is more or less what I did, as I was NOT willing to make multiple visits for their techs to "diagnose and try things" before they finally offer to replace the pump itself. I paid high at around 1800, but quite frankly it was a fantastic shop and every other shop in a 20 mile radius either...

  18. Oil Pump Control Valve before Oil Pump Warranty?

    Thanks a lot man, I’m trying a different dealer next week

  19. Updated oil pump?

    ...tests they performed on my car, they went as far as to lie about the data that they claimed to have found. They also insisted it wasn't an oil pump issue, but a software issue. I just think they didn't want to work on my car. I have left a Google review for that dealership here. I've also...

  20. Oil Pump Control Valve before Oil Pump Warranty?

    When the time comes to get my oil pump replaced, I'm taking it to an independent BMW shop. Although, 1400 with tax isn't bad at all to replace with parts/labor.
