Need pin code for Citroen C4 keyless key with slot 2016.
Autel IM508, OBDSTAR G3, Autel KM100, AVDI Abrites, Xhorse Key Tool Max pro all failed to read pin code via OBD.
Eventually read with OBDSTAR DC706 by mcu on bench. OBDSTAR G3 also read pin if you have ECU flasher license.
ECU type: Bosch MED17.4.4. Read pin code from ecu on bench mode via mp001 programmer.
FYI:
Xtool can read pin code for this model via OBD.
