After FW update (900>1100>1200>2760>3800) my unit is without communication with the CAN-BUS. I lost the MFD, the buttons on the MFSW, the device turns off every 30 minutes and there is no lighting on its buttons.
I tried several downgrades/upgrades, but no succes. Only the first time after downgrade to FW2760 everything was ok, but it was temporarily. After reading maybe thousand posts, I replaced the old CAN gateway (3C0907530E) with a newer one (3C0907530Q). Well recoded, but the problem remains
If anyone has encountered this problem, please advise.
