I thought I saw a post on this but couldn't find it ... so here it is ...
what you'll need
T30 Torx driver (about 3" long)
10 mm allan wrench
Blue Lock tight (optional)

MAKE SURE YOUR STEERING WHEEL AND WHEES ARE STRAIGHT BEFORE YOU BEGIN

Step 1 - see photo
Insert the T30 driver through the holes in the back of the steering wheel to remove the air bag ... I did not disconnect my battery but you might want to.


Step 2
Remove the 10 mm alan bolt (sorry no picture)

Step 3 - see photo
Note the position of the steering wheel and remove it

Step 4 - see photo
Remove the 2 philips screws. Remove the black part (do not open this ribon cable holder ... it will never be the same

Step 5 - see photo
Remove the 3 philips screws that hold on the mulit-switch. The big phillips screw shown in the background is your problem. Remove the multi switch

Step 6 - see photo
I removed the bolt shown and added a bit of blue lock tight ... once you tighten this you're turn signal/cc wont move when you activate them

A broken clock-spring could indeed cause an intermittent short, let us know what you find.

Nice post, durado.

Take care and enjoy the ride,
Greg

What does the writing on the back side of your turn signal lever say? Kind of a weird place to have writing...

E320 97 | Combo switch issue

Same problem – starting fist with the whole combo switch been very loose, then high beams will be turn on every time I will touch the lever and finally the cover of the switch at the steering column just get loose and hang over the lever. And yes, it gets the switch really loose with high beam on constantly. (I was able to switch it off by putting my fingers inside the switch). The reason – the switch lever swings worn out and almost broke. The remedy – order a new OEM switch for 110 $

Thanks for the pics! My blinker is stuck flashing left in the neutral position. I bought a replacement at the local Mercedes salvage yard for 40 but they gave me the wrong one. At least removing the 10 mm bolt will be easier when I do get the right one. Had to use a breaker bar. I wedged a bicycle pump in the steering wheel so it would not move...which helped a lot.

Thank you for the great pictures. I needed 110 foot pounds to remove the wheel nut! Also, I did not see in your instructions to unplug the airbag at the airbag side of the harness (yellow connector) and leave the gray connector attached at the post. I tightened the internal clamp and all is well. In fact this went so well I may purchase a new steering wheel for my 06 E320 CDI. Great job.

Durado- Thank You for your detailed post. I just finished fixing my loose stalks and, thanks to your step-by-step DIY instructions, the job was a snap! The help in this forum from guys like you is greatly appreciated, I only hope I can repay the favor someday by adding my own how-to. Thanks again.

Question: Have to replace cruise control stalk--210-540-07-45-- but can't find the wire plug to remove the unit. Also,bought a 21--545-022 from Ebay supposed to fit an E320 maybe does but not mine, it is setup for left and right levers. Looking at the 2 units closely, the wiring is exactly the same except there is an extra wire (7 lilac) instead of 6 on the old unit. The basic questing: getting rid of the wiring harness leading to the second lever and the control unit in the housing wouldn't that make it conform to what I need? Hate to experiment until someone with experience offers an opinion. Any help is much appreciated.
