    One for UKOBD

    BMWCA1 BMW 20-pin to OBD2/EOBD Convertor Cable

    "Compatible with most petrol BMW's from 1997- if you are unsure whether your vehicle is OBD2 compliant"


    How will I know whether my 1997 E36 328i (UK model) is OBDII compliant?


    And if it is, will this work with standard OBDII readers and in the same way?

    A 1997 UK model is NOT OBD2 nor EOBD compliant. OBD2 is only used on vehicles sold in the Usa and Canada. In Europe we have EOBD but that was not mandatory until 2001.
    Other signs of non-compliance: No 16-pin EOBD/OBD2 connector,
    No Oxygen sensor(s) after the cat.

    Well, that's what I understood, hence the question above on finding that lead on their site.

    I understand now. One would assume that a UK seller knows that OBD2 is a thing from across the ocean and has no meaning in the UK.

    In actual fact a 20-pin to 16-pin EOBD conversion cable will allow you to use a standard scanner with your petrol BMW. The ECU was compliant from 1996 as the US law required it to be so, but they did not fit the 16-pin socket for the EU market.

    The best tool for the job however is the FCX-3 (http://www.ukobd.co.uk/gstore/store/...?IDproduct=124) as this covers the BMW propreitory codes as well, and enables service reset.

    Well I would want to be using it with the car PC.

    I currently have a lead and interface which allows me use to the Carsoft software which I will try to write a plugin for.

    However if I can get something which will allow me to use a standard OBD II device it will make writing or using an existing plugin easier.


    And if that device also allowed the BMW propriety codes as well even better. (esp if it had a SDK)

    UK and all Europe sold Bmw's from 1996 up to 2003 (when a diesel) DO NOT SUPPORT any protocol of EOBD. The 1996 thru 2000 models do not even have a oxygen sensor behind the cat so there not compliant with anything.
    I think the Bavarian technic is an excellent tool for BMW. Still a lot to develop, but they will get there. info here: http://www.bavariantechnic.com/

    Not sure where this information is coming from? Why would anyone even both producing conversion leads if this were the case?!?

    The information is coming from me and I know this because I did a lot of chip-tuning for these BMW models. Now I do it a little bit different than other tuners, because I am a software engineer old style. That means I can read, understand and write Assembler code.
    I always disassemble an eprom to see what te program it is doing. Gives me more control over certain functions. Now I have found the factory diagnostic protocol, but there's no trace of any OBD2/EOBD protocol in 1996 thru 1999 petrol ecu's.

    A strange one indeed. As I mentioned before the FCX-3 would always be my preferred option, as has all proprietory codes as well.

    All I can say is that we have supplied loads of these cables (and the Merc version) to clients, and haven't had any complaints or issues.
