Has anyone experienced an engine whining noise at low speeds usually in 1st-2nd gear? Usually occurs after engine/oil warmed up, driving 15 mins. When in park, no whining noise when revving. No noticeable change in performance, no error codes on OBD scanner other than “21B2C7: Engine oil pressure, plausibility: absolute oil pressure too high “. No issues measuring oil % in idrive. Just wondering if it’s typical of B58/ZF trans. 2021 m340i x drive, about 60,000 km (37K miles). Some sound clips driving 5-20 mph in 1-2 gears:
Taking it to dealer for a road test but wondering if others have seen this. Thx! |

After I did my transmission and front and rear diff fluid changes, there was a short period of time where there was some whining. After a few hundred miles of regular driving it completely disappeared. Car is as quiet as can be. But, sometimes diffs just go to shit. You’re under warranty it looks like so let them check it out. But please do report back if they find the issue or what was needed to be done to fix it.

Quick update. Dealer said everything is normal after a road test. I had to pay for a diagnostic which I decided against. Maybe I’m a little too OCD but their response is laughable… “it’s the turbo” to which I reply “your foot is off the gas and car is slowing down, how is the turbo whining?” At this point will wait and see if it gets worse, then go to another dealer. Typical of my local dealer here in Laval, Quebec to say everything is normal (have a few more examples). To keep costs down they prefer something completely fails before looking at it regardless of any BMW TSBs.
