Retrofit comfort seats in my 545i 2004

[Grundtvig]

I have a 2004 545i pre-lci, born with standart full electric, memory in drivers seat and headed seats.

Yesterday I bought 2 frontseats, its the pre-lci Comfort seats. They also have the full electric, memory (in both sides) and headed seats. But the have a little more electric adjustment settings in the seats...

What do I need to retrofit these seats in my car?
Do i need any electric units or can it be done with some coding?


Hope you can help me, and sorry my bad english I do my best I'm from denmark.

Hi! Did you get it to work already?
I just changed the fabric electric (non-heated) seats and upholstery (doorpanels etc.) in my '05 E61 to leather upholstery and (heated) comfort seats.
My seats now do not move via the switches on the side......
Yellow plug under the seats is different. (logical I guess since they're heated seats now and additional headrest tensioner)
Still looking for a solution too.

Thanks!
