    Hi folks. Could anyone please advise if OBD 2 connections are standard across modern cars (those with OBD 2 ports of course!), or does each manufacturer have it's own unique connection/plug?

    I am looking to buy some diagnostic software and an OBD 2 to USB connector but want to be sure I get the right connector.

    Help appreciated

    You car will have a standard OBD2. Mine has a round one in the engine compartment, but saying this...it also has the same OBD2 port under the driver side dash..not even sure if this is connected as I never tried hooking it up to my notebook...might give it a go one day to see what happens
    As for your connection, these ports require a RS232 serial interface, so make sure that your usb cable can do that.

    All cars made after 2001 will have an OBDII port, it was made mandatory.

    the signalling protocol for the OBDII functions is generic, its only the vehicle specific that is not, such as the coding for the ECU etc.

    A few people on here have Carsoft and get on well with it, if your lucky one may chime in

    Thanks Ronnie.

    Anybody use Carsoft 6.5? Any thoughts on how good it is or recommendations on any better diagnostic software at a reasonable price?

    Cheers
