I removed a steering wheeel the other day on a w201, used a stubby philips on the airbag and came off fine. the hex screw that holds on the steering wheel is pretty tough though. I go to the yards' and play doctor on cadaver 201's which is good practice.
I would rather try on a junked one first. sure ,it's some labor but it has helped me understand some of the nuances about these cars, also got the CD from MB ($60) which has paid for itself many times over.
