Cause:
In isolated circumstances, it can happen that the multifunction camera fails to log into the data bus CAN in the temperature ranges (23 \A1\E3F to + 41 \A1\E3F
and 68 \A1\E3F to 86 \A1\E3F). A fault code entry is not made. Following a renewed ignition sequence and a change in component temperature, the system is
operational again.
Remedy:
Replace MFK and calibrate with the aid of the "calibration target for Night View Assist" special tool (W 000 589 01 20 00).
