Hi all,
Very interment non start (crank but non start), happens for us once every couple of days, 3rd crank then will start, Fault code B2139 keeps coming back.
Engine control unit and immobilizercommunication/ transponder fault Communication error
Tried the spare key, still the same and the red immobiliser light goes out even when it wont start.
Totally unsure where to go from here, any advice much appreciated.
