...only appeared after about 5 minutes of driving as I tried to replicate it on cold starts but wasn't successful. After they replaced the oilpump I no longer hear the noise and have tried numerous times to replicate it since the fix but it's all good now.
But yeah I would take it to Toyota...
Just double checking, but did you hear this whine when you pulled away from a light? Did it feel like you lost a little power for a second? I'm trying to diagnose a similar whine with my 2020 and want to get it sorted before the warranty is out.
Also how often did it happen? I tried having my...
On Bimmerpost I’ve seen at least one person mention they had a whining noise coming from the oilpump (along with inability to measure), which was resolved after replacement, so hopefully that’ll take care of it for you.
Ha well, “blown out of proportion” is a bit subjective, but there’s...
...to your dealer if you see a trend in the wrong direction. on my X7, oil level didn't read the first time i tried, but worked the 2nd time. i'm in the monitor stage currently.
Edit: I'm also still not confident that there is a new design oilpump. imo it was a bad batch(es) of pumps that went...
Update: dropped my car off 11/12/24 got a call 2 days later on 11/14/24. Service advisor told me that the oilpump was ordered and currently waiting for parts to arrive they did not provide me with an ETA. The whining noise concern I have as-well has not been addressed yet, they will look into...
2021 here at 22k miles no oil consumption over the 2k miles I’ve owned it this year. Also no issues reading oil level (another thing to watch for which is a symptom of oilpump issues).
I've resolved this issue on my setup and believe I found root cause. The latest theory behind the exhaust cam VANOS deviation is that the increased fuel rail pressure adds additional load on the exhaust cam due to the cam-driven high-pressure fuel pump working harder to create that pressure...
Yup, bumping oil pressure 4500 rpm + by just a little worked for me. Even at 29psi boost.
I got it once on track, and right after a shift at high RPM. I run 5w40.
Since I'm currently chasing this issue, I figured I will also share my research. Short story, for most people newly encountering this issue after adding power and/or HPFP, this is tuning related.
To preface, I had a tune finalized w/ stock HPFP and pure850. The stock pump was pushed to its...
100%. I loosely referred to this info being North America focused in one of my earlier responses, but I should have reiterated it for good measure. (Get it? Measure. I’ll see myself out).
Great info. It’s interesting how much the issue varies. What is the production date of your car?
@kern417...
I have 58k miles on MY2020 - my oil level still reads fine and oil pressure is normal on idle and under wot.
Normal oil pressure at idle is 2.3-2.7 bar
Under wot the oilpump will normally not exceed 5.5 bar
if you need it, this is the BMW oilpump: 11419895359
Let me guess… level measure failure and high pressure (if you had access to a scan tool)? :(
Edit: If you happen to know the production date of your car that would be interesting. Regardless, it’s anecdotal data gathering unless/until BMW produces a SIB outlining a manufacturing date range for...
...the G29/J29. That’s a bit beyond the scope of this thread, and there’s plenty of information online if you’re interested.
There are reports of oilpump failures (can’t measure, high pressure) across both TU variants. If you search Bimmerpost, you’ll see a few threads centered around the...
...Supra have different B58 variants in North America, but both are B58TU. “TU” refers to a generation of engines and not a specific model. The oilpump failure is also a problem for the M340i which has the same variant (B58B30O1) as the 2021+ Supra.
Observationally, the oilpump failures seem...
Could be a bad pump, but I thought on the b58tu (2nd gen) BMW changed the oilpump back to all metal components? So the oilpump failure hasn't been an issue on any 21s and up. Oil level monitoring seems to have been a problem even when the dealership put on new pumps hoping it would fix the...
Definitely the oilpump. How many miles and has the car always been in California? (I’ve seen some comments that there may be a correlation with cold weather, but nothing tangible).
