Thanks for the reply - I have had it in the garage and the switches seem ok. Also replaced the amp with one from e-bay and it still had the same problem :( I've now pulled the fuses so it stops discharging the battery but it's still not fixed and I haven't got enough dosh to take it back to Audi..........

The MMI in my '55 plate A6 4.2 keeps constantly rebooting, even when the car is switched off and locked. I have to disconnect the battery to stop it discharging overnight. I have tried the three button reboot and holding the mute button down for ages but it just boots up again then turns itself off and then reboots constantly. Help please, it's driving me nuts...... When it latches on, all the components seem to be working fine but then it turns itself off and reboots again... grrrr see pic: MMI booting and no key in the ignition........
