Your wis maybe too new. Mb removes older diagrams. Try using an older wis version. Or look for star finder 2008.

The diagram I sent is correct. U have no immobilized on your car? (No red green lamp on mirror ) then yes another ecu from any c220 will work. The wiring is all the same. I used wis 2010 for your diagram. What's your question re CAN H And L?

Merry Christmas to you too
Yes another HFM ecu will work without any issue. It will work the same as your current ecu. CAN H L has nothing to do with OBD. Like I said with no immobilizer you can just plug it in and start it up. I have test units I just plug into customers cars for testing. No problems. I have even used w124 units in a w202

Russel i did some further investigation ! i cleaned the spark plugs then it didn't back fire until the plugs become black again !! i think its out of mixture !! and it gives a terrible smell . well is the mixture controlled by the ECU and does my modle has a co2 potentiometer like in this vedio ? and i can see two sensors fitted to the exhuast manifold and the one after the catalytic !

If it has 02 sensors it will NOT have co adjustment. Does it start? What is the coolant sensor value? U need a scanner to see value. What spark plugs are u using. F8DC4 Bosch plug is the correct one. Maybe just renew plugs.

Ok. Well until you get your launch there is not much we can diagnose! Ovp only supplies power to ecu.. is the valve timing ok? No major airleaks?
