XC40 from base interior to memory seats

[iGeorge3]

Thanks for the feedback!

What would be the best thing to do then? Replace the interior as-is without swapping the seats ECU or swapping them?
If I disconnect the ECU before any service wouldn't that throw some error codes and just confuse any Volvo technician?

My goal would be to change the interior and still service the car in volvo workshops, to benefit from their coverage in case of major issues.

What would happen if I swap the ECU with mine and before any workshop visit I just revert the configuration to the original one? I believe it wouldn't throw any error message, just that only lumbar support would continue working but the rest of seat adjustment won't work at all?

Other than that, wiring doesn't really scare me in the whole thing. It's mostly the communication part and Volvo service that I'm worried about.
I'll have to check about the CEM pins however, I didn't know there were multiple levels. Is there any part number or writing to look out for on the label of the CEM other than the missing pins themselves?
