The sound for the red AP disconnect button on the yoke has no sound right now. 

Thanks noted.

I have problems with the autopilot when I turn it off, the warning light doesn't come on and the sound keeps going on all the time.

The external lights keep giving me errors, they don't light up or they don't light up the A330 in general.

Hi @ALBERTO

You need to use the red AP Disconnect button on the Yoke (A300) or Sidestick (A330) to disarm the autopilot. Press twice to disengage the function and appropriate aural/visual warnings. If you are using a keybind, that button is mapped to the AUTOPILOT OFF command in MSFS control settings.

Also note, this forum section is for the A300 premium. For A330 related issues please report on the MS Forums or seek community support here: https://forum.inibuilds.com/forum/520-a330-200-300-300p2f/

Thanks!
