Massage seat only on drivers side?

[AnttiH31]

Passenger and driver seat controllers are independent. You can replace only the driver seat with the controller came with it and enable the massage option only for driver side.
Side supports and massage are the same controller built in the seat ECU. Since you already have the side support,  I would connect the original seat controller to the new seat and enable the massage option from Orbit to see if it works.
This will save you the headache of "hardware changes" recognised by VIDA.

If the new seat with the original controller does not work, you have no choice other than using the new seat together with its own controller.

I swapped out the seat and tried to change the config to have the massage function on just the drivers side seat. It didn't work despite resetting all ECU's.

I changed the config to "massage front seats". The function appeared but didn't work. After resetting all ECU's once again, it started working.
