Having some trouble with LED reverse bulbs and BimmerCode.

    Installed a set of Diode Dynamics LED bulbs and I can't get them to stop flickering. I used BimmerCode to change the settings for the reverse lights to LED, still no dice... From what I'm reading on other forums it could be related to cold monitoring but I can't seem to locate that particular setting. Has anyone solved this mystery?

    I couldn’t get a pair of very reliable Philips Ultinon LEDs to work, no matter what I tried. I switched to YuLED-branded Auxito bulbs and they just worked.

    I haven’t looked for anything in Expert for the reverse lights, but try to find KALTUEBERWACHUNG and WARMUEBERWACHUNG and set them to “Nicht_aktiv.

    But more than likely, it’s just the bulbs.

    Rückfahrlicht is "reversing light" ... these look kinda close maybe? (I would've thought 'RFL' instead of 'RFS', but worth a shot.)
    RFS_L_IS_LED = aktiv
    RFS_R_IS_LED = aktiv
    RFS_L_KALTUEBERWACHUNG = nicht_aktiv
    RFS_L_WARMUEBERWACHUNG = nicht_aktiv
    RFS_R_KALTUEBERWACHUNG = nicht_aktiv
    RFS_R_WARMUEBERWACHUNG = nicht_aktiv​

    Periodically, the warm monitoring will rapidly toggle the light on/off to check for a fault. Incandescent bulbs are too slow to respond, but LEDs respond much quicker, so it shows up as a visible flickering.

    Reversing signal, maybe? Rückfahrsignal. Thanks, I'll give it a look!

    I tried DD also, contacted them and they recommended wiring in a resistor, I gave up
