Hi from Spain!, I have got a Mercedes CLK320 year 1999 with a 38 pin socket.
I have tried to check it with a OBD 2 PROTOCOL CODE READER, but it is not compatible with my car. Could you give me any information about the PROTOCOL which works on my car?.
I would appreciate a lot any information you can give me. Thanks!!.

PD: I have a 38-pin adapter for the code reader.
