The 3 of 4 electronic door locks on the G80 would not open... didn't matter whether or not I was using the touch point on the handle, the key fob or the interior door switch. Only the driver's door would work. If you manually opened a door by unlocking it from the inside they would lock electronically properly. Dealer checked all smart items on the car and all circuits tested that the signal was being sent but not acted upon. Finally mechanic decided to disconnect battery and do a capacitor discharge. That worked. We are hoping this was an anomalous situation. Procedure also showed me that none of the settings on the radio or info panel are lost when disconnecting the battery.
