CAN error codes, on the gearbox.

What can cause these please?

Problem with the datalink between the engine ECU and autobox ECU, bad contact, wiring issue or ECU fault, first of all make sure there's no oil in the engine ECU red plug cos the CAN connection is there and oil can act as isolator, also the wires are going through C0448/0162 pins 5(white) - 6(yellow) wires check that too (give contact spray) and make sure the pins are nopt loosened

Thanks SF will check tomorrow
