    Hi all, I'm looking to update the software on my 02 E65.

    I know my local specialist will do this for me, but I would like to do it my self.

    I have looked all over the net but there doesn't seem to be much info about it.

    Any ideas what I need to do it?? Or how??

    why do you want to up date it ? , to be honest you have an early car and they where prone to softwear crashing when being programmed , if this are working on your car i would leave well alone.

    I just thought it would be better have the latest software.

    Few things keep playing up, like sat nav crashes, had a phantom side light bulb failure. And i thought a full software update may solve a few issues.

    I know the early 7s are prone to bugs.

    BMW North America are offering 24 hour access to their site for a fee of course. Would that work?

    How do I plug into the car?

    Or is it that likely to crash I just shouldn't go there!

    diagnostic leads and software which is hand for fault codes and adaptations
    this one is the easiest to install
    Why should I purchase from BM Technic? « BM Technic | BMW Diagnostic Cable | BMW Diagnostic Software

    Wow that looks very handy and for only £30.

    Will I then have I download software from BMW?? Or can I torrent it off the interweb?

    Do many people use it??

    The diagnostic software mentioned earlier is indeed very good. I have a similar one that does all I need it to, but apparently that bmtechnics is the easiest to install. Mine came with 41 pages of instructions and took 4 and a half hours to do with a couple of emails flying back and forth because I ran into problems. I wouldn't mess with the software. Could definitely do more harm than good it just sounds like you have standard bmw gremlins. I've had sat nav crash on my old 2002 e53 (now deceased) before and phantom bulb failures aren't unheard of either. My old e46 used to tell me the rear lights were out all the time and they weren't!

    Your car uses a MOST bus to perform software updates.

    That means ideally you would use a fiber optic interface to upgrade the software of your ECUs.

    A genuine MOST interface such as the "pass through" costs around 1000£, while the BMW one (ICOM) costs around 1800£ and more.
    Now you can get a chinese clone for about 400£, but this is seriously risky.
    Programing also involve using a power supply to provide permanent current to your car. This is not a battery charger. A good power supply that will handle at least 50 amps will cost at the very least 200£.

    Now even if you decide to flash your car using an OBD plug you are asking for troubles already. It was done in the past but be advised it will take at least 10 hours.

    There is no such thing as a 30£ cable that can patch an advanced car like a E65 without some extra hardware and software.

    Personally I would strongly advise you against even thinking of patching your car to the latest software using a 30£ plug. Even using the original equipment is long and risky.
