Cruise Control, Gear Shift and Turn Signal levers rotate on column
I've never taken a steering wheel off so I'm hoping there is another option.

Have the same issue on my Ml320 cdi. haven't repaired it yet. because it hasn't irritated me enough yet.
judging from the how the the w203s are done and mercedes being pretty consistant in how the put things together, it shouldn't be that difficult.
- behind the steeringwheel, there are 2 holes on either side of the steering wheel. these are for loosening the airbag. use a `T30 torx tool. to do that.
- once you've untied the airbag , make sure you remove the airbag connectors . make sure the key is out of the ignition!!!!
- You can then remove the Steering wheel using an M50 key and a torque bar if you have. make sure steering is unlocked or else you'll damage the steering lock
- Once Steering has been removed you should be ale to see the the indicator storks etc and hopefuly where it bolts on.
I sould be repairing mine over the weekend and will try taking pics
