Retrofit heated steering wheel problem. Help!

[Orman]

Ah ok. The part was tested OK before disassembly, so it should be working. I have no other way of confirming that myself, so I’m just going to assume it is. My original part is manufactured 2019, and the replacement I purchased is manufactured 2020, in a different country as well. All the other numbers printed except part number doesn’t match either. I don’t know if that has anything to do with it.

Part numbers always change for same exact parts almost every year.  I do not see the picture but search for your original part number or the replacement part in google or here https://usparts.volvocars.com/ .  They should be Supersession(s) of each other. You can even get a third different part number as the current one.

Solved.

Volvo dealer reloaded the software and everything is working correctly now.
