    Hello Vlad,

    Thank you for your enlightening article. I am at my tethers end with an electrical, I think, glitch in my E93 passenger side mirror. And I am really struggling to find anyone who could shed some light on it.
    I have folding, heated, mirror glass adjustable side mirrors and my passenger side one stopped folding one day.
    Then a few days later I could no longer adjust the mirror itself but it would still dip when I was reversing! Then that started to work intermittent and I sometimes ended up with a downwards dipped mirror frozen in that position.
    I took a chance and bought a secondhand mirror on ebay and installed it myself and it worked!
    Only for a month though because yes, the mirror stopped folding last week and a few days ago it stopped adjusting but it still was dipping in reverse but would not completely go back to its memory position.
    I am trying to trouble shoot: First I am checking whether the original motors on the old mirror have blown due to an electrical short by an electrician. Then I am going to check the wiring loom and connectors for broken wires, faulty connections and or corrosion on the connectors. Do you have any ideas what could be causing this? Could the FRM be at fault and if no mechanical issues have been found might it be a signaling fault in the LIN bus?

    Kind regards,
