    True, but still need to check if K1 and K2 lines are ok as these control the hung bus in most cases.

    K1 and K2 are the two diagnostic lines on the car. One is for Engine ECU & EGS and the other is for everything else.

    Edit: seems your reader only does the engine, so only 1 of the two lines will be needed.

    I would avoid DIS. It required you to do a lot of hacks and set up a fake LAN bridge to the USB port, it has taken some very software savvy people days to configure and even then is very version specific in its support. Follow my guide here to get INPA.

    Hi,

    I'm quite a novice on this stuff, especially considering 02 plates are miles from my E30, but, you say that these other indy garages managed to read the codes...I'm guessing they may have had a generic type OBD2 code reader, I know that they aren't as accurate as the peake ones for BM's as they don't read the factory codes, so that could be why/how the indy's are possibly mis-diagnosing the fault....though it's weird that the fault was fixed temporarilly, even still it's possible...could be cause they just managed to clear the codes! It would be good if you could fine someone with one of the generic type code readers just to see if it can pick anything up, although you wouldn't have thought it would if the K line is hung....

    Just some thoughts...

    Usually Indy's have a rather expensive tool like Autologic, which is pretty powerful, yet still operates within the bounds of the single wire data bus on the 16 pin connector for this year of vehicle.

    Also there is no evidence of a hung bus as yet, it's some sort of red herring. The bus operated at 12V and 0V for signalling. Pulling it to 0V by accident will not break it, only mute the ECUs.

    Using a multimeter to check if the bus idles at 12V is a good test. 5V is is a dead master bus controller and bridge (in the KOMBI) (for which there is a backup in the LCM), 0V is a dead short in the wiring.

    I have a generic ODB-II Reader and software on the laptop and was able to read generic codes from our 1999 E46 through the ODB-II port under the steering wheel. However, these were not the Airbag and ABS as the Generic ODB-II reader can't get to that.

    I have an ELM-327 Reader + ScanXL Pro. Great for my ST200 but pants really for the BMW. Nice drag strip and digital rolling road - if I ever suss it out.
    Car:BMW 318iSE (E46)
