Did you VO-code everything correct? VO-code all affected ecus

Yes all ecu's coded.
In ista - Abl left steering wheel switches all buttons is correct and no fault memory

Hmm I have no real clue then… did you buy the correct steering wheel buttons?

I mean after I searched I found that BMW x1 uses a bit unusual button layout compared to other BMW’s. TJA button is switched, if you look up my post in the Post your F48 photo there I have a working steering wheel photo after replacement of the cruise control knob.

I think you don’t have the right buttons hardwire wise….
Which year the F45 was from? As you can see realoem should you have part no https://www.realoem.com/bmw/enUS/par...&q=61319326475 but this is only in production since 01/2016 so if the wheel comes off a pre 2016 F45 then this might be nonexchangeable retrospectively.

Do you happen to know part number of the buttons?

Did you also add 5AR and 5AT to VO?
