It might help if I explain what I want to do. Bob (my neighbour and good friend) has diagnostic equipment for OBD2 and offered to loan it to me . Yesterday I borrowed both Bob and his equipment for an hour but everything halted when he looked at the connector and said- 'its different'. Bob has two european cars both of which have the ISO version of OBD2, both have the same connector but its different to Mercedes or certainly different to my 98 300 turbodiesel. Any information or advice would be good, or a pointer to anything on the net.
