    F10 535i - Harmonic balancer wobble

    Hi guys,

    Do you think this harmonic balancer wobble is normal ?
    There is slight engine vibration and even more when AC is switched on.
    Engine mounts, transmission mounts, tensioner and belt were replaced six months ago.

    Or could it be a bad AC compressor?

    They all do it. Some worse than others. Replace the balancer if it makes you feel better. I have seen a few AC compressors on N55's lock up, but that's not what's causing the wobble.
