MIB2 DRAIN BATTERY. I CAN FIX THE ISSUE WITH M.I.B. ? HOW ?

[AudiTT2016]

Good morning everyone.
I have a problem with the MIB2 unit of my AUDI TT 8S 2016.
MIB2 drain about 1.5 amps even the engine car is stopped. I hear the MIB2 fan continuosly running, also after several hours with car stopped (with windows open in order to hear the fan).
The MIB2 unit works correctly (sound, radio, phone, navigation, USB, etc.) with no warning/alarm messages on the virtual cockpit.
The normal operation is that some minutes from turning off engine car and the virtual cockpit and open doors, the MIB2 fan should turn off.

Could the problem fixed with a M.I.B. ? How?

Thanks to anyone who can help me.

Best regards
