T-cross 2022 rear seats weight sensor problem

[alessioblaupunkt]

Dear Vw experts,
T-cross year 2022, the car has indash display for rear seats occupant.

The rear seats has no occupant but the car say there is one passenger on passenger side and has no belt.

The belt state IN THE DASH does not change if it is latched or not.
The belt ohm value DOES CHANGE if it is latched or not so belt BUCKLE WORKS.
The OCCUPANT IN THE DASH does not change if passenger is on seat or not

I have Brain CONNEX to scan the car but won't cover this model completely.
It only display codes with no description.

Which electronic unit does collect all the info for weight and belt??
