Because the 202 chassis was born at about the time everyone was preparing to use OBDII protocols, the car became the first MB to use such. You should be able to read codes. I doubt if you will be able to get a freeze frame or be able to view monitor status. No actuation testing will be available.
As David says its a big maybe. As I said, its my opinion, that the 94 will do at least code retrieval and clearing and some actual values. Probably no more.
