Hello friends, I have problem with audi 4f 2006y mmi 2 g... I dont have idea what to check next I need wiring diagram/pinout for control head 4e0035729. Mmi "restarting" on radio every second cut sound and play 2 secs. On cd cannot load nothing but if I change from 1. To 5. It goes back to 1. Track.


Tryed with optic bypass every module same thing always.

In gateway with vcds no dtcs but when i try to connect to 07 control head I sometimes can connect to module but cannot read faults, sometimes cannot connect to module. Tryed another control head module same thing... +12 v on two red wires and gnd power is ok I think its CAN fault... 

Please if somene can give me wiring diagram to check can bus where is comming to 07 module i have 4 green wires on connector and where can goes from control head which pins on gateway. Thanks

Bluetooth is a separate unit located under the driver's seat. disconnect it use optic bypass.
