    Carsoft EWS syncing is either poor or non existent.

    The codes you have are Map cooling thermostat (common problem, and not a big issue) and DME/EWS communication.

    With the battery going flat, it is likely that the rolling code tables have been unsynchronised, and you'll probably need it to be re-aligned with better BMW diagnostics, either DIS/GT1 or possibly INPA.

    try to diagnose with BMW gt1 / OPS/OPPS/Icom.I think useless if you use carsoft.If the problem is the key unrecognised,then your key is damaged.Change the chip inside the key and program it with bmw keymaker.That's all,you can't synchronised the key if it is unrecognised.
