Next time you get the key to turn (if there is one...) you MUST leave the key turned!!! (I have had success by turning against the key and wiggling the steering wheel back and forth until the key turns.) The tumbler cylinder has failed and you need to order a VIN keyed tumbler from Rusty, your local stealership, or MB Classic yesterday. Remove the cylinder at anytime after you get it to turn. Turn the lock to position 2 (run position) and insert a paper clip into the small hole on the face of the tumbler. This will allow the black ring to unscrew off the cylinder. Replacement is the same as removal.
Here is a tutorial on how to remove the cylinder if you cannot get the key to turn. http://dieselgiant.com/mercedes_diesel_maintenance_tips1%20page%202.htm Hope this helps.
