Seat Retrofit -- New Module is throwing codes

[Shyrik]

Do I need to connect them one by one to do the reload or can I leave these two modules connected at once?

You can have them both connected.  If the replacement units have the same HW number, there is a chance that VIDA would not show them in the HW changes TAB.  If it detects, you can order and install them one after another. The order does not matter. 

What you need to do is. 
Restore all config to OEM from Orbit
1) Connect the original PSMD and PSMP to the seats.
2) Connect the VIDA and do a readout. 
3) Check the HW changes TAB under the Software Installation main  PAGE.  If you see the AUD or WAM or both.  Since you put the original  PSMD and PSMP, they should not show up there. 
4) Order and install AUD and WAM if they show up in the HW changes TAB. 
5) Order and install total upgrade. 
6) Perform fresh readout from VIDA. 
7) Order Configuration change and retrieve but do not hit on install yet. 
8) Replace the  PSMD and PSMP with the new ones.  While VIDA is connected and ready to install the configuration change. 
9) Click on install the configuration change. 
10) Do a fresh reload, at this point, VIDA should not show the  PSMD and PSMP under HW changes.  If they do appear, this means VOLVO has changed the logic. You will need to put the original  PSMD and PSMP back and reorder and reinstall the configuration change So that, VIDA removes the detected HW changes from the VOLVO servers. 

Configuration change app, scan the car for any equipment and software config changes and reports back to VOLVO servers updating their systems.

Hi. I bought a 3-day subscription to Vida.
I have messages about the necessary loading of the replacement modules.
WAM and AUD and IMS(I don't understand why I need to reboot this module, I haven't changed it. But I have no other option.   )

I would like to clarify what it means to do a configuration test. I have the ability to download this ( 31493703 configuration test ). This service costs money. I thought it would be a free service. Was I wrong?

I also replaced the SWM module. I had a module without heating (32230871), I installed a module with heating. (32230872). 
Is there any way I can install new software for the heated steering wheel or do I have to try to trick the car the same way as with the seat modules (configuration test).
Thanks
