    Hi guys, hope everyone is doing well.

    My F12 has a flat battery (been away for 2 months due to Covid travel restriction and quarantine) and i just finish charging the battery for 2 days, managed to start the engine up but have few problems:

    - Power windows on both passenger and driver side is not functioning
    - Fuel refill door not opening
    - Air con has air but its not cold (i think the thermostat is not kicking in)
    - TPMS, Electrical system failure, suspension fault (all these will just go away on its own after a few drives)

    May i know is there anyway we can self fix the first 3 problems instead of sending it to the workshop? Sometimes the staffs at the petrol station will give me this look as if i just stole the car and have no idea on how to open the fuel cap, but instead it just reluctant to open and i have to embarrassedly drive away. lolz

    i read somewhere it says to disconnect the battery for 10mins to reset the system, is it true?

    D

    You need to reset your system after a dead battery. Hot switch your ground lead and then follow the reset procedure using the remote per the instructions in the owners manual. This will get your windows and such working but you need to replace that battery asap.
