That is a great DIY. Pictures detail every step. Even just reading through that, I feel that I could just follow those instructions to the letter and have no problems. Great job! 10 outta 10 there!
Out of curiousity (first time i've seen it appart), can the audio buttons / controls be easily removed from the airbag center piece? I'd like to replace my left hand audio controls (buttons) but before this couldnt see 'where' they were attached.
Again. Great write up.

Thanks for the positive feedback!

Wow, nice! Anyone know where to get a heated steering wheel, and how the install process would differ with one? Where to the controls go for the wheel, and how does it get wired? Thanks!

turn signal switch
Hi guys, I did a search for information on switching out the turn signal switch. Seems it's not a common problem but I was wondering.....does anyone here know how difficult or easy it would be to remove the old turn signal switch after having removed the steering wheel?
I appreciate any advice or info,
Henry

^ Yes AFAIK.
A call to my SA confirmed that you DO NOT NEED TO DISCONNECT THE BATTERY when performing this procedure. He never said anything about whether or not you could have the key in, but I wasn't about to try.
Holy geez that 10mm allen bolt was crazy tight. I actually distorted (ie partially "stripped) the bolt a bit trying to free it up. Half the bolt was covered in blue Loctite. Holy geez.

Awesome pictorial. Having the right tools at hand, it only took 15 minutes to change my wheel. Knowing the center bolt was going to be gorilla tight, I had no issue with my air impact wrench at the ready. Thanks !

Note: I know this is very basic stuff, but I would've found this helpful when I did it. Plus I wanted to see how much work it was to do a write-up and would I have the patience to do a write-up on something like this(?):
Comprehensive GReddy turbo installation
It's just a kitchy little mod like the euro-trunk insert I'm doing next. Please don't call it 'Rice'....
...the term would be 'Kraut'

This steering-wheel swap was done on a 2002 AMG C32. Probably all Mercedes steering-wheel swaps will be similar, but things like a heated wheel, paddle-shifters etc... will change the procedure slightly.
A fairly detailed W210 swap how-to can be found here.
Obviously any time your doing something to or near an airbag, you should take precautions suggested by your vehicle's manufacturer. Even if the airbag didn't hit you in the face, you still have dangerous gasses and a huge mess and expense if you accidentally trip it's trigger. In the case of the W203, it's sufficient to keep the key out of the ignition during the procedure. Placing the key in the ignition at any time while the airbag is disconnected will throw an SRS fault code and only a dealer can clear it. Disconnecting the airbag and reconnecting it is fine as long as the key is out of the ignition.
As paranoid as I am, I didn't disconnect the negative battery lead as recommended by my shop, but I did establish visual contact with my keys at key moments in the procedure.:icon_redf
I pulled the stock steering-wheel (nearly identical to what's found on my wife's 4-matic wagon...
...which is pretty mundane given the general manner of any AMG)
My replacement is the steering-wheel from an F1 Medical car!!!
(which is a station-wagon itself - the irony is unbearable)
Here's the medical car steering-wheel
I used the following tools for this swap in (this order)
T30 Torx
Small common screw-driver
10mm Allen socket
Torque wrench
The procedure:
1. The wheels should be pointed straight-ahead. Fully telescope the steering-wheel and locate the two small holes with T30 Torx screws about a 1/2 inch in.
Right side of steering-column
Left side of steering-column
2. Remove the T30 Torx screw inside each.
For the Torx, my T30-driver was too long, even with the wheel fully telescoped so I used a T30 bit on a 1/4" socket attached to an extension from my smallest socket wrench. The T30 Torx screw will loosen completely, but it won't fall out as it's part of the assembly.
On the left-hand side I had to flip the turn-signal all the way up to get the tool in there.
3. Gently tilt the airbag down and away from the steering-column and disconnect the upper lead - Yellow Jacketed wires with a black, plastic clip.
4. Locate the two airbag leads. Use a small common screw-driver head to flip up the small tab with a looping piece of plastic. Do this for both leads (Yellow and Green on my car)
Use the screw-driver's head to pry up the tab like this
It comes straight out and will look like this when it's all the way out
Pull the entire plug straight out - it should come out pretty easily. Now do the same thing with the green plug.
5. The airbag assembly should now be completely free. Place it in a safe, clean location with the Mercedes Star facing up (I've heard that they are really safe at this point, but still, I figure if it accidentally went off, it would just blow the bag UP this way, and if it had it bag-down, then I have the metal backing of the airbag assembly going who-knows how fast in my garage).
You should now have a large Allen bolt visible at the center of the steering wheel.
6. Use the 10mm wrench to remove the counter-sunk Allen bolt at the center of the steering-column. This bolt is in there pretty tight. Even so, with my torque-wrench as a cheater bar it came right out. Have a friend hold the wheel in the manner shown. Don't work against the steering-wheel lock, you might break it.
7. Carefully pull the steering-wheel straight away from the steering-column. Guide the wires through the holes in the steering-wheel as you do. This will reveal a finely toothed inner shaft.
8. Align the new wheel with the toothed inner shaft. Carefully feed the 3 free leads through their proper holes. The steering-wheel will have notches at 0 and 180 degress which should line up with yellow or brownish dark lines on the inner shaft.
(sorry about the bad pic, my camera doesn't like close shots - I'll take a new one soon)
9. With a friend holding again, torque the counter-sunk Allen bolt to 80Nm or 60 ft-lbs
10. Plug in the green and yellow airbag leads. Connect the black top-lead. Align the airbag and attach it by tightening the T30 Torx screws from the back of the steering-wheel.

I'll never understand people that bring up an 11 year old thread just to write an inane response to a 2 year old post.
