Swapping seats. Do i need to program?

[Rev Engineer]

For what it's worth, I swapped in a set of comfort seats (from a 2004) to my 2001 with base seats. Everything just worked, including the seat heaters when I swapped in the console that has the seat heater buttons. No coding required.

I guess I haven't looked closely if the seat memory is following the car key since I only use 1 key.

Regarding the k-bus error, I see that one all the time when I read some modules (can't recall which ones), but I think it's a don't-care in my case since everything is working ok.
