Art's Quickie Turn Signal Fix. Art's technique worked perfectly for me. My slipping turn signal switch assembly on my Mercedes e430 (W210) bugged me to death. My OCD went nuts because the dust cover underneath the gauge cluster moves as the switch assembly moves and the embossed lines would not be correctly aligned. Eventually, I guess it could become so loose as to cause other problems. Either way fixing it is a good idea.
Here are the steps I followed:
1. Mark location to drill for access to the screw that secures signal assembly. Make sure steering wheel is straight then mark a spot 1 3/4" down the column shaft cover from the base of the steering wheel and down 3 1/8" from the horizontal seam in the cover (Art, the original creator, called this second measure the 5 o'clock spot if you were looking at your steering wheel.
2. Drill a 5/16" hole being careful to stop as soon as the drill bit is through the cover plastic.
3. Align turn signal switch correctly by utilizing the horizontal embossed lines in the dust cover on top of steering column underneath the gauge cluster.
4. Tighten Phillips screw located inside the cover approximately 1 1/8" directly above the access hole drilled in #2. I had no problem simply inserting my screwdriver into the hole.
5. Install some sort of plug in the hole (optional for aesthetic purposes.

And Voila! No more rotating switch assembly. Easiest 3 minute repair ever.
