Mine would not lock from the keyFob from collection . Eventually at the dealer they found that one the front bonnet catches was slightly out of adjustment ( easy fix ) - you need to be sure it takes 2 "pulls " to open the bonnet otherwise you can start and drive the car but only lock it from the key ( which may not alarm it ) - the detail on start screen that shows one of the doors are open does not include the 2 bonnet interlocks but you may get a alert showing a bonnet with red and a few bongs with no text ??Today I tested mine and no matter how I tried it would not lock itself. It will only re lock if I unlock it with the remote but then fail to open one of the doors.
Mine has the latest 1946 full update, so perhaps Ineos have cured the problem?
It has locked fine every time since then
We really at the very least need some simple sequence diagrams ( flow chart ) to diagnose issues - INEOS where are the promised electrical / electronic diagrams ???
