Heated/massage seats and dealer visit

[gerjovolvo]

Hello everyone!

After quite some considerations, i want to replace my XC90 ’21 Momentum seats to at least heated/massage front seats. Electric/ventilated is a nice to have. Currently on the hunt for some good quality seats from same modal/year.

However, after reading this topic:

I understand I need to ‘revert’ the changes when it goes to visit a dealer, but what steps, practically needs to be done apart from going to OEM with orbit? I need to put back my complete seat because of the ECU? Or can i just disconnect some wires? Anyone has experience with this?

First of all, you should always revert to OEM any config changes before visiting the dealer or connecting the VIDA to the car. If VIDA detects any unofficial config changes done by Orbit or any other third party tool, VOLVO will block the VIN (Car) for any further software reloads including for officially replaced modules at the dealer. 
Having said that,  
VIDA will detect any replaced modules and will force you to reload before allowing a total upgrade. Please note this does not mean your car is blocked for software reloads. 
VIDA will reload replacement modules only if the part number of the replacement module is listed for your VIN. 
You have two options depending on the replaced seat modules that came with the replacement seats. 
1) If the part number of the replacement seat modules is listed for your car's VIN, then you can reload the replacement modules and VIDA will not bother you again. 
If the part number  of the replacement seat modules is NOT listed for your car's VIN, VIDA will not reload giving you error this software is not suitable for your car. The downside is that VIDA will only throw that error only after purchase of the reload software is completed right before the installation begins.  So, check the part number before you connect the VIDA. 

2) If the part number does not match to your VIN. (In my case because I retrofitted S90 seats to my S60).  
You will need to either disconnect the seats before connecting the VIDA or put the originals back. 
Now, disconnecting the seat harness will throw DTCs for seat controllers and the SRS airbags since it won't detect seat airbags.  At this point I do not know if VIDA would still allow total upgrade with those DTCs or not but at least it wouldn't detect HW changes and force you to perform software reload. You can then put the original controllers back, perform the total upgrade if it does not perform total upgrade due to DTCs caused by the disconnected modules.

Thank you for you extensive description, your remarks in the other topics are very helpful. 1 additional question:

If the part number  of the replacement seat modules is NOT listed for your car's VIN, VIDA will not reload giving you error this software is not suitable for your car. The downside is that VIDA will only throw that error only after purchase of the reload software is completed right before the installation begins.  So, check the part number before you connect the VIDA. 

Since i have a Momentum, only 1 part number is possible? So let's say i would get XC90 `21 power-seats from an inscription, it will still throw an error or there is a possibility it will accept? Or would in this case Volvo provide it as an option? Since some modifications can be turned into official. And something like this with the steering wheel does work. That can be retrofitted officially.

If the part number the replacement seat controller from XC90 Inscription is listed as supersession to your original or your original part number is a supersession of the replacement, then VIDA would reload the replaced module and update the VOLVO DB. But this does not mean that it will also enable the additional features. It might with an additional software reload, or it will keep the original features which you can always enable via Orbit. 

If the part numbers are not supersessions of each other, VIDA would not reload the replaced controller. In this case, it would be best to disconnect the connector under the seat before connecting the VIDA.  Otherwise, you will end up like me. I had to connect the original seat controllers back to the car and reload software before I could do total upgrade.

eyy. you said that you couldn't reload your seats because it's from a 90 series in your 60 series. I have retrofitted from standard fully electric seat and semi electric seat for the passenger to fully ventilated electric seats with massage and memory from a s90 2023 in my v90 2018. will vida reload those seats in my car? where can i find corect part numbers for my car # in EU so vida is not avalible here for regular customers

You can check on the VOLVO parts website. Search for the part number of the replacement unit. If it shows that it fits for your model / year than you are good. 
In my case, s90 / 2018 part number did not show up for my s60 /2019. Some parts are interchangeable but some don't just like the 1st gen B&W AUDs. 
90 series B&W AUD are different part number.
