Would anyone know if the BCM is interchangeable as long as its like for like.
Going on my problems with this interlock code , I am trying to narrow this down to my BCM is corrupted.
Any knowledge out there appreciated please.

Thats some good info, I think on that basis its worth the risk of changing the BCM with a Bcm with the same part number.
It maybe stuck in transport mode but the Gap says I have deactivated it. So along with the non existant countdown it may be goosed , and oh the left headlight wiper has a habit of not parking right , also I think the steering is on the stiff side.

Update , .........Not good !
Changed Sat nav and Bcm and still locked!
I can't believe that no one especially Land Rover has no info on this .
I've been back and round and repeated everything.
Perhaps the immobiliser ecu needs a refurbish .

Well after the 20th reboot of the car systems and genrally replacing the BCM and Sat Nav I got the countdown and the car started on zero!
God knows what I did!

Absolutely excellent news.

It’s not often we get stuck on this forum….. but this was a strange one.
