Edit:
This swap is for users who want a facelift wheel, example e55 swapped to e63/cls55 wheel
The 2020 wheel is my personal touch
Reason for the swap is I’ll be doing some product testing of a w205 swap but worst case I’ll just rock a 2020 wheel
I’m not responsible if anything gets damaged. Use diy at your own risk
Edit: I don’t know if something like this will work for sl55. If I find someone who wants to dive in maybe we can get something going but it’s a long shot
some programming maybe involved for paddles; I haven’t run into this personally just from what others have said
If anyone wants a wheel made for their w211/w219 feel free to visit
wow didn't think a steering wheel from a much newer model would fit the W211 that easily! usually splines differ and obviously wiring but you did it!
my #1 worry is if the airbag would still work, but that's a 1-time, very expensive test so i understand. certain other OEM airbags changed from single stage to dual stage so i'm unfamiliar if this was done with MB over the years too.

spline needs to be modified but that’s very easy to do. Need a marker and an angle grinder.
as for the airbag deploying. Unfortunately it’s been tested when the first retrofitted car was in an accident and all the bags deployed
I am in the process of upgrading my clockspring on my 2004 e55 and the female connector on the clockspring for the paddle shifters is a different size. Do I need a different wiring harness to connect the paddle shifters? The female plug on the new clockspring is larger and for a different plug.

whats your goal with updating the clockspring? are you installing a facelift w211 wheel? if so look for one thats a complete package, paddles,airbag, harness ect
I was putting in an updated steering wheel from a w212 with the harness and airbag. I also picked up the module for the newer shift paddles - I am not sure I wired those properly either. I attached photos - can you take a look and provide any guidance? I appreciate the help. The white plug is different from the female connector on the clockspring. I did also purchase an updated steering column piece that houses the clockspring. This is the updated closkspring I bought. One of the used steering column housing with the cloaking was broken so I bought a new clockspring This is the paddle module - I am not sure I connected it properly.

the write up I have is updating a w211 prefaclift steering column to a facelift. You’re trying to retrofit a much newer setup. Totally different
I doubt my wiring instruction will work with that.
maybe start by pulling up the schematics for w211 clockspring wiring and w212 to make you’re custom wiring harness
good luck
I have a 2006 E500 with an old cracked leather steering wheel, got a much better one with wood. Went to remove the old one and looks like there’re no screws in those wells on the side of the steering wheel.
Do I just pry the airbag out?

iv never in my life seen those bolts missing. If the bolts arnt there the airbag would just fall out
I looked at the steering wheel I was going to install in place of the old one in the car and figured it out!
The screws are deeper in those holes and concealed, they are integrated into the steering wheel and don’t come out! Silly me!
