I have done a fair bit of research on this and reckon I am where you were a few nights ago!
I'll continue to look into it when I get any time as it interests me.
OK .. still no luck.
At this stage I'm not getting any hardware errors but only the dreaded "Cannot communicate with unit. Try again?"
Heres what I did.
1. So I tried every setting in the book with regards to setting the USB FTDI converter .. but no luck on either of the modern laptops running Windows 7 ..
2. Not giving up I installed Windows XP SP2 on TWO more machines .. an old Dell Dimension 2450 desktop (20GB HDD so its OLD!) .. and an old Compaq Evo n400c laptop with docking station (this machine has a COM port on the laptop and the docking station!). None of these machines worked.
I also used a COM port 'monitor' and see commands go to the device and the bmwscanner device return some information (thought to be a 'cant communicate with car' code to the software)
So to summarise, I have tried:
- Prolific USB with Windows 7 laptops
- FTDI USB with Windows 7 and Windows XP laptops
- Modern laptop with COM port with Windows 7
- I have tried using different compatability modes with Windows 7
- Old laptop with COM port with WIN XP SP2 - also tried the docking station COM port
- Old desktop with COM port with WIN XP SP2
- I have been using 'bmwscanner1.36', 'bmwscanner1.35' and 'bmwscanner1.4demo' for each test to see if one would work and the other not
- I have tried with the car idling and with just the ignition on
- I have tried several times EVERY setting from 1 to 100 milliseconds for the 'delay' in the bmwscanner software
- I have always had the green power and red k-line lights lit on the bmwscanner box
- I now only ever get the message "Cannot communicate with unit. Try again?"
- I am only using the 20 pin round connector under the hood (my car does not have the other connector)
- So I have tried 4 laptops (1 new 3 old, 2 old with built-in COM ports, and a docking station COM port) and a desktop (built-in COM port) to date ;o(
I really did think I could beat this but am running short of things to try!
The ebay vendor (some hong kong guys) are trying to assist but apart from telling me not to use USB and to use a 'genuine RS232' they have not come up with any other ideas. I have asked them to join this group to assit on this thread.
I will persist.

Do you have a diagnostic tool working?
What is it, where can I gaet it and what computer would I need?
Have several working, I'll respond in more detail tonight. I feel that Pasoft BMW scanner is best for your issue. I have read of people using it for E39 cluster issues.
You ever near Bristol?
Right, shouldn't really link to other forums but.... I take it you have read this thread? http://www.bmwland.co.uk/talker/view...=asc&start=100
There's a post on the page I linked to which suggests using 9600 as the baud rate. I have never had to adjust the baud rate before for any diag gear. There's also examples of people getting it working on there!
From what I have read the install is meant to be straight forward!
A thought occured to me which you probably tried but didn't mention - with Windows 7 did you turn UAC off or run the app as an admin?
I'd stick with trying with the old laptop as it's one less thing to worry about. Have you got another BMW you can try to communicate with?
My E36 is probably quite similar to your E39 comms wise. I have used Carsoft on Vista using a USB to serial converter successfully before. I have also used Inpa on Vista using the Vagcom lead but you cannot talk to the instrument cluster on older cars that way. I have used that setup to talk to an E39.
Currently, I have a dedicated diagnostic laptop that's running XP and an ADS interface. The laptop is on old crappy thing with 712mb of RAM. With it I use Inpa 99% of the time as it's quick to use, I can connect to the IC with it. I also have GT1 running in a VM that talks back to Ediabas on the XP host which then talks to the car. You can do a lot with it but it very much walks you through things which I find slow and frustrating. The interface was about £100.
Just to clarify about Inpa/Edibas. Inpa is the front end that talks back to Edibas.
Thanks for all that, I have NOT read the thread (missed it somehow!) .. so will do now.
Also, have not tried baud rates less than 9600 so will try that too .. and will turn UAC off.
I'll let you know how I get on .. fingers crossed!
quick update .. still no luck getting this to work! if anyone has please email me!
So I just got the EDIABAS/INPA and I'm having trouble with that as well .. http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT .. lets put it this way .. the software doesnt fully work for me ..yet (forever the optimist!)
Is it possible that the OBD is not working somehow? At this stage I'm starting to blame the car .. its an oldie I got so who knows whats its been through ..
Can someone suggest an easy way to 'test' the OBD in my car?
Anyone live in the Surrey area with a scanner willing to meet up quickly just so that I can prove the OBD on my car works!!! I'll meet you and it will be quick!
Are you getting errors?
Did you set the system path?
Yes, I set the system path and am using software that only connects via ADS or so it seems since it does not have the OBDSetup.exe program. The connector in the link above .. should it use ADS or STD:OBD?
I diagnosed a combination of problems using this document .. which is GREEEAT!
.. The famous INPA FAQ!!
At the moment I'm searching around for another copy of EDIABAS and INPA, and Carsoft .. any idea where I can get them? ones that work that is! PM me?
