U0065Vehicle Communication Bus E Performance
- Generic OBD-II code · Network
- How the car detects it
- U0065 reports that Vehicle Communication Bus E is present but its communication is unreliable. In Audi and Volkswagen gateways this slot stands for the infotainment CAN. Audi lists U006500, labelled there as no communication on the infotainment CAN, in gateway J533 of the 2015-18 A3, paired with U111000 in the instrument cluster: the infotainment unit will not switch on, cannot be operated or goes blank now and then. The cause is a grey 12-pin contact carrier not slotted correctly into the quad-lock connector of control unit J794; both parts are replaced. Volkswagen's 2017 Golf family campaign 91Q1 warns that the gateway may store U0065 during the infotainment software update because J794 drops off briefly; such entries are intermittent and clear.
