Hello Gentlemen,

All of my previous cars have had leather interior, and I really am missing it with my 4-series. I have found a good deal on an interior with leather, heated, memory sport seats.

Now the big question is, how to do the installation? The mechanical work isn't a biggie, as I already have taken the interior apart for speaker upgrade.

Electrics? Do I need to do a lot of wiring? I already have the electric heating and lumbar support in my current ones, so there is at least some power going to the seats.

Codings? I have a setup to do coding, if I know what to code.

I believe the seats have some kind of modules, can it be a problem that the car doesnt recognize the new ones at all?

My car is a 420i 2016.

Thanks a lot and your help is highly appreciated!

I suggest to start with www.realoem.com and become very familiar with parts required for your project. The next stop: obtaining wiring diagrams.
