Steering wheel swap question
I bought a pre-facelift w204 c63 steering wheel. It has the round buttons which is same as the one on my e550 so no column swap should be needed.
Anyways, I plugged in the new wheels and the buttons light up only. Paddles, horn, buttons all don't work. Anybody have done this and can troubleshoot? Most people swap out to the facelift wheel with a new column but I opted for pre-facelift on purpose so I didn't have to change the column.

Did you remember to disconnect the battery before you started?? That may throw some code issues.. I do recall seeing several MB wheels (Pre FL vs FL) that appear to be the same button configuration but then something like arrows are in a different place button wise and thus they needed a new SW column.

I got it all figured out thanks to some help from the E-coupe FB group. I swapped over the PCB board and all is working. Even though both wheels are PFL, the buttons , horn and paddles didn't work until I swapped the PCB over.
