I have scan tool, but an easy one. This week i'm going to go to the local MB Dealership, and read the ecu with original MB scan.
What I can explain, that there is a broken wire somewhere between the purge valve and the canister area. Those wires goes somewhere inside the car. Measuring where is the broken one..hell of a job is it
That CEL makes me crazy all the time i drive the car.

Yeah I guess you could ohm out all the wires and check resistance. What a sucky job
