Vauxhall Meriva-B 2011 Transport/Logistics Mode Stuck

Hi AP, not posted for a long time sorry.

I hope someone can help me with this:

I have this Meriva-B that seems to be stuck in what's known as either 'transport mode/logistics mode/battery saver mode' where the vehicle is in a low power state with limited functions until this mode is deactivated during the new car PDI.

On this Meriva the battery light flashes constantly and the interior lights won't work unless the key is in. Also the central locking won't unlock with remote or with the dash button but it will lock with the remote.

Live data in BCM under 'power mode data' shows 'Logistics Mode' as ACTIVE
On a good identical vehicle this shows as INACTIVE.

I have seen several methods of disabling this but none work. For example, hazards on, foot on brake, start the engine and keep the key over for 15 to 20 seconds. I've tried other variations of this and still no joy.

Neither GlobalTIS or GM Infotech show a procedure for the Meriva but they do for Astra, Insignia, Corsa, Zafira-B etc, which makes me wonder if the Meriva has this function in the BCM but it's not normally used?

Has anyone seen this before?
Any ideas much appreciated.

Thank you!
