check continuity of the knock sensor wiring and its sheathing, the wires are shielded.
you may need to redo the wiring if its internally broken.
and as mentioned above, if you physically hear a spark knock from the engine and the timing doesnt change, you have a duff knock sensor. I think these old benzes used a plain knock sensor that is tested with a hammer strike to the engine.
