Thanks MB DOC. I'll try tonight. I was on my way to take the bottom part (knee bolster0 below the steering wheel off but got stuck at the point where I need a long neck socket to reach up to the bolt (my socket extension thing wasn't long enough so I couldn't get a good look at the surrounding of the tumbler housing.

I did many searches for W202 but was unable to locate any info related to the tumbler on 202.

Many thanks again.
