I have a MB CLK 320 cab - 1998 and it does not have a OBD2 connector.

Does anyone know of a PC based diagnostic tool (or any other tool) that fits the 38 pin connector that does not cost a fortune? Like CarSoft, which is to expensive for me.

Does anyone know the pin configuration on the 38 pin diagnostic connector or where I can find information about it.

Thanks for your help !
