    Problems with SGM/SIM and EGS please help !!!!

    Hallo everyone,


    My car is BMW E65 2008 diesel. I have problem with communication with some modules like SGM/SIM, EGS and some other from time to time. I think everything is related but I don't know where to start. Attached I have photos of my ISTA results.
    Any opinions are welcome. Please help me.
    Thanks in advance.

    you probably have a bad module thats pulling down the can bus. You may also have a bad gateway module, Or a damaged/corroded terminating resistor.

    These cars are an electrical nightmare, ive spent many many many hours solving no communication faults on these cars.

    Hold up.
    What cable are you using? K+DCAN?

    Go into your FTDI drivers (device manager) and set latency to 1 or 2msec first.

    The Windows default is 16msec and causes issues with communications all the time.

    328 Power 04, You are an angel. I just tried and I removed all the errors I left only with the initial one which is for the sgm/sim module, but in comparison with before it is great. Thank you very much. I've been reading your comments for the last couple of weeks and you really know what are you talking about. I can not try the car now because I drink a couple of beers, but will be the first thing tomorrow and will let you know. Attached you can see the results after I cleared the errors.

    You're welcome. The only real reason why I knew this is because it happened to me. Windows 10 will set that value back to default every time it will automatically update the drivers (another reason for me to hate win10), so keep an eye on it.

    Enjoy your car!

    You can try a flash update on the SIM/ZGM with WinKFP to possibly get the control unit internal fault fixed, but it's a little risky with cheap K+DCAN.

    That is an ENET cable (Ethernet), and only for F-chassis and up, not E65 like yours.

    You can update SGM/SIM module with a simple but qualitative K+DCAN cable and WinKFP program.

    Hallo I alredy have ICOM cable and tried to run test plan with ISTA +. After the second step it said that it will reset the SGM/SIM module but it needs charger, so I did not continue.
