M340i Engine Whine

stunatu72 · 01-21-2024, 02:30 PM

Has anyone experienced an engine whining noise at low speeds usually in 1st-2nd gear? Usually occurs after engine warmed up and driving 15-20 mins, with and without vents on. When in park, no whining noise when revving. No noticeable change in performance, no error codes on OBD scanner. 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).
