I'm trying to sort a misfire problem on a 2002 A-Class Mercedes (Petrol).
As far as I can tell this car should be OBD-II compliant. I ordered an ISO OBD-II toy from ebay, based on the ELM323 chip, but I cannot get it to work. I have also tried it on a 2004 Renault DCI-80 (Diesel), doesn't work on that either.
Can anyone please confirm that both the Merc and the Scenic are OBD-II complaint?
TIA
