    Got this cable from a friend as I used to have a skoda, never used it, but just had a thought.... would it be ok for my e46? It looks ok compared to the KKL vag-com leads everyone seems to get? Any pin outs that I can buzz or should I just give it a go?

    If you have a round socket under the bonnet on your 2001 you must use that one to gain access to all the modules.

    A 16 pin to 20 pin adaptor can be purchased from China for a few quid.

    It's just the one under the foot well.

    I made up the cable with a transistor, resistor and 7+8 (I think it was) connected. It isn't working, but I think it might be to do with the version of INPA I'm using. Waiting on an older version. Will post back later.

    Gotta ask is your port allocation correct?

    I changed all to Com port 1. ini file and the device manager. Going to download the older version of INPA, see if that makes a difference.

    An older version of the SW will not improve your hardware issues. It will however bring you additional script issues to resolve when you overwrite new scripts with old.

    Did out my INPA success thread and follow the steps therein.

    Hi joylove, good to see you post in here (was hoping you would!) Your thread has been the backbone of me trying to understand how to get this sorted.

    I have gone back to the beginning and have only shorted pins 7+8 on the Vag-com cable. I'm pretty sure thats all that is needed on the hardware side? I was faffing with resistors and transistors as per other threads but I've backtracked now.

    If you want to talk to the engine and gearbox you only need the K line found on the 16 pin connector. If you want the ABS, Airbag or anything else, you need both K lines found on the round connector. Handily both K lines can be shorted to get a simple OBD2 K USB adaptor to work.

    [For those of you with pin 7 & 8 fitted on your 16 pin OBDII socket, the pins can be shorted in your USB OBD2 adaptor and you don't need the 20 pin connector. For those of you without pin 8 fitted you have an option; pin 25 on the socket X11175 (right instrument cluster connector) carries a White/Violet wire with D_TXD1 and you can add the additional wire to your OBDII port.]

    OBD2.8 and OBD1.20 carry BMW's 1 wire DS2. OBD2.7 and OBD.17 carries the gimped OBD2. You will not at any time speak OBD2 to the car.

    Since you will probably want the full suite of modules INPA software offers, you need a BMW 16 pin to 20 pin adaptor. This has a wire inside that shorts pins 17 (K) and 20 (K), and connects them to 7 (L).
    I've used the above for the basis of what I've done.

    I followed your instructions and this is as far as I can get....

    It looks like you are trying to access the wrong module.

    Try a few different engine ECUs. DDES0K47 would be the first one to try.

    Right, thats telling. I used Teraterm to test com1 (everything is setup as bmw-and-inpa-success-e39-e46-onwards thread) and I get nothing. Something must be up with the driver right?
