Are you sure your start/stop button hasn't just worn? 2015 Range Rover Autobiography 4.4 SDV8 |

The button is fine. When the code is cleared it starts/stops instantly. If/when the code reappears, it's as if it's dead (until it starts that is!). -------------------------

And simple things like when the batteries were last changed in the key fobs?

Both key batteries were changed when this malarky started (Duracell!) and it made no difference. Keys are working fine. -------------------------

It will be reporting a real situation but it could be caused by either a wiring fault or a motor fault, so should be considered in light of the other behaviour but could also be the cause of the other behaviour. I would persue the door locking fault because there is something concrete to chase, at least whilst the fault persists. |

Success! Can’t say exactly what did it, but I dismantled, unplugged, cleaned and sprayed all connectors related to starter button/door mechanisms/steering column/immobiliser/ and even scrubbed and starter motor and battery terminals/fuse box connections. Since then there have been no phantom errors and the car starts faster than ever on the button - every time. I’m going to perform similar actions moving forward on any jobs I do around the car as a while-I’m-in-there precaution. One day I’ll have all connectors cleaned and sprayed!

Great! Did you clean the temrinals on the distribution block behind the battery as that one seems to be a regular culprit for general electrical problems. |

I haven't had to clean mine yet but the battery will need to be removed to gain access, then just remove the nuts and terminals to clean all the contact spots with a light sanding. |
