If you remove 8TR from their FA and save it back, then VO Code the 3 ECU listed, LCA should then work. It will also persist beyond any future software updates.
You could also FDL code LCA using the codes I published in 2019, but those changes will need recoding with each software upgrade.

I think I might have found the origins of 8TR Surprisingly it is not due to Statutory Regulations or hardware but paint!

Still does not explain the vehicle in question as it is Alpine White which is non metallic Maybe BMW got it wrong when they set up the factory FA?
