    Hi All......first time poster here.

    I'm having to pull fuses to shut down the MMI 2G overnight which is getting a bit boring..haha
    New coded battery and alternator fitted so i know thats good.
    Charges at around 14.6v.
    Everything works as it should.
    Latest firmware installed as i was hoping that would cure. It didnt.

    The mmi screen shuts down and it looks like all is good but when the car is locked the amplifier in the boot stays on and drains the battery.
    I have tried another amplifier but the problem remains.
    The parking brake light on the dash and button also stay on until i pull the mmi fuses.
    I have scanned the car and the only fault coming up is the air quality sensor. I can clear it but it keeps coming back.
    I would really appreciate any advise on this and where to start looking as it would be lovely to not pull fuses

    Thanks in advance folks.
    Cheers
