I have been trying to find clear instructions on how to achieve this installation successfully over the past few months, I kept giving up due to confusion, frustration, misleading threads and bad information. However, after much research, I have finally got it working and hope to help others searching for solutions. I can't guarantee that this is absolutely perfectly described but the process below worked in my case, hopefully it'll get you up and running too.

My specific use is to diagnose codes on my E46 M3 (2004) and so I can confirm that it works fully with this car. If someone wishes to take screenshots, I'll add them to the guide.

Assumptions and Clarifications


  • This setup/installation DOES work on Windows 7 64bit.
  • This setup/installation DOES NOT require VM/Virtual Machine images.
  • This setup/installation DOES work on an E46 (my car).
  • This setup/installation DOES give you INPA and EDIABAS 6.4.7 and 5.0.2.
  • This setup/installation DOES NOT give you NCS Expert or anything other than above mentioned.
  • This guide assumes that you have a basic knowledge of Windows, Control Panel and Device Manager.
1. Buy a cable

I purchased a USB cable from EBay, it came with software but I didn't use it and instead used online resources that I downloaded for which I'll provide links. The cable I purchased is a USB to OBD2 connector that plugs into your BMW to the right hand side of the steering wheel, in the foot-well area.

This is the specific cable that I purchased and that I can confirm works:
BMW Diagnostic Software Cable lead Ediabas Inpa DIS SSS | eBay

2. Download the software

There are many sources on the internet for INPA/EDIABAS, some seem to work, others do not - I used these specific downloads and they worked perfectly:

** UNFORTUNATELY THE DOWNLOAD LINKS ARE NO LONGER AVAILABLE - BUT I WILL SEE WHAT I CAN DO **

If for any reason the above links are missing/broken, PM me and I'll see what I can do. Thank you to whomever is hosting the above files and I hope that you do not mind me providing these links.

3. Setup/Configure your OBD2 USB Cable


  1. Put the DVD that arrived with the cable into the DVD drive on your PC.
  2. Plug in the cable into a USB port on your computer, you must ONLY use this USB port from here-on for this cable. If your computer is connected to the internet it should automatically search and install in the USB cable drivers. If your computer does NOT automatically detect the cable, you may need to use 'Device Manager' to manually update/select the driver.
  3. Once installed, go to Control Panel -> System -> Then click on the Hardware tab, then click on Device Manager.
  4. Locate the entry 'USB Serial Port' in the 'Ports' section of Device Manager. It should read ‘USB Serial Port (COMX)'.
  5. Right-click on the above and select ‘Properties’, then click on the ‘Port Settings’ Tab and then click on ‘Advanced’.
  6. Change the 'Com Port Number' entry to 'COM1'.
  7. Change the 'Latency Timer (msec)' to '1'.
  8. Click on ‘OK’ and close all the windows, restart your PC to confirm all the changes.
4. Install INPA/EDIABAS 6.4.3 and 4.4.7


  • Extract the contents of the downloaded file 'INPA-6.4.3-full.rar' and you'll find a .NRG file. This is a CD image that you'll need to either burn to a CD or extract to a folder using a tool such as ISOBuster.
  • Once extracted, go into the following folder '/REFERENZ/INSTALL/', right-click on 'INSTPROG.exe' and select 'Properties', click on the Compatibility tab and change the dropdown to Windows XP SP3 as the Compatibility Mode, also tick 'Run As Administrator', then click 'Ok', then double-click the file to run the installation.
  • Select 'English' as the language and click 'Next'.
  • Select 'Next' until asked for 'Configuration', scroll to 'BMW Group Rectification Programs UK', click 'Next'.
  • Tick the option 'Complete' for all of the options shown.
  • Select 'Next' and allow the installation to start.
  • After a minute or so, installation will complete, close the Window.
5. Verify environment variables


  • Go into Control Panel -> System -> Advanced System Settings.
  • Select 'Environment Variables' and then verify that the System Variables 'TMP' and 'TEMP' both contain the path 'C:\EDIABAS\Bin' within the 'Value' string - for instance "C:\Windows\Temp;C:\EDIABAS\Bin".
6. Prepare Installation Files


  • Extract the contents of the downloaded file 'INPA_502_Updated.rar'.
  • You'll use the contents of this archive during the next three steps.
7. Install BMW Tools


  • From the above extracted file set, find the file 'Step 1_ Install BMW Tools.exe', right-click on it and select 'Properties'.
  • Click on the Compatibility tab and change the dropdown to Windows XP SP3 as the Compatibility Mode, also tick 'Run As Administrator', then click 'Ok'
  • Double-click on the above file to start the installation.
  • Set the Destination Path C:\BMW Tools (Don’t change this path) -> 'Install' -> 'OK'.
  • Select 'English' -> 'Continue' -> 'Continue'.
  • Select 'C:' -> 'Continue'.
  • Select 'Skip' -> 'Next'
  • Accept the defaults for programs to update, then click 'Next'.
  • Select 'Com1', 'OBD' and 'USB to Serial Adapter' -> 'Continue' -> 'Continue'.
  • The installation will begin and complete.
8. Install INPA/EDIABAS 6.4.7 and 5.0.2


  • From the above extracted file set, double-click the file 'Step 2_ Install INPA.exe'.
  • The Destination Path should be 'C:\temp', leave as it is and click 'Next'.
  • Choose 'English' and select 'Continue' and 'Continue'.
  • Select 'C:\' and then 'Continue'.
  • Select 'BMW Group Rectification Programs UK' and click 'Continue'.
  • Tick 'Update' for all options where not grayed out, then 'Continue'.
  • Select 'OBD', then 'Continue' and 'Continue'.
  • The installation will begin and complete.
9. Install OBD Setup


  • From the above extracted file set, double-click the file 'Step 3_Final Update.exe'.
  • The Destination Path should be left as it is, then select 'Install'.
  • Select 'Yes to all'.
  • Once completed, the window will close itself.
10. Complete Installation


  • From the above extracted file set, double-click the file 'serial port.reg'.
  • When prompted, select 'Yes' and 'Yes'. You will receive confirmation that your registry has been updated.
  • Locate the file 'C:\EDIABAS\Bin\obd.ini' and copy this file into your Windows folder.
  • Edit the file 'C:\EC-APPS\INPA\CFGDAT\INPA.INI' in Notepad, locate the section that starts with '//F3', remove the slashes at the beginning of the three lines of text, and amend any instance of 'F10' to 'E46'.
In theory, you'll now have an INPA icon on your desktop and Start Menu - right-click on it, select 'Troubleshoot Compatibility', it'll select 'Windows XP SP3', click 'Next' and 'Save'. This step isn't necessarily required, however it apparently provides a little more stability for the application.

Now, with your interface connected via the USB port (remember NOT to plug the cable into any port other than the port that you originally configured the cable with) - and the other end connected to your car, fire up INPA and hopefully you'll have a working diagnosis tool :D

Apologies for any inaccuracies, please do PM me and I'll make corrections, but to my knowledge the above is the exact process that I used to get mine up and running.

Finally, I'd like to thank FAL for his help/assistance with getting my setup fully working :D

Good luck! - PLEASE POST YOUR FEEDBACK/SUCCESS (oh, and any failures :D)

just a quicky ya don't have to be on COM1 ya can select any port ya like so long as you select the same port choice during the INPA installation, and why its always better to set the interface up first before installing inpa etc..

in truth there is no need to force summat already on COM1 to another port if your COM1 is already being used by a device...

Very true, I was going to put this into the guide but as I hadn't tested it, I thought it best to just replicate exactly what I did :)

First, kudos for the DIY - nice write-up! :thumbsup I bought the same cable (plus a OBD1 adaptor as my car is an OBD1 1993 E36) and I was looking for something tested and working for Win7 x64.

Second, I'd like to know what "BMW Group Rectification Programs UK" is? Is it something UK RHD cars specific? Only asking as my car is a LHD and made for and sold in Germany. Do I have to select something else, German specific?

Also, you said INPA.ini should be edited and any instance of F10 replaced with E46. Is this because you were looking at configuring this mainly for E46? If so, should I replace F10 with E36 - as this is the car it will mainly be used for?

Thanks!

Gabriel

LE After reading a bit more, apparently, no OBD1 car will communicate with this software unless you have a proper serial com port. So basically, the cable I bought is pretty much useless, being an USB cable. Is this correct? :frown

Glad that you found the guide useful, be sure to 'rate' it too :D

I have to admit that I don't know, it might change the language set depending on which option you choose, I would be interested to know whether the other options perhaps unlock other areas of programming, but I'm unsure. Just be wary as you can do some damage if you don't know what you're doing.

Also, you said INPA.ini should be edited and any instance of F10 replaced with E46. Is this because you were looking at configuring this mainly for E46? If so, should I replace F10 with E36 - as this is the car it will mainly be used for?
You won't have to make the 'E46' inmod in the last few stages as I believe that E36 does indeed automatically appear under the option 'Old Models' from the home screen of INPA, verify that and let me know if not.

After reading a bit more, apparently, no OBD1 car will communicate with this software unless you have a proper serial com port. So basically, the cable I bought is pretty much useless, being an USB cable. Is this correct?
Nope, you'll be fine - the adapters that we purchase include a serial-to-USB converter and therefore the system will install the cable as if it were a new COM port. If you've bought the same cable as me, just follow my guide to install the drivers and then configure the new port

Let us know how you get on!

Thanks guys for taking the time with the IT noob here! :hihi

OK, returned the cables and bought different cables with RS232 serial connection. Will probably have to buy an old laptop with RS232 port. Can I still use this software, or do I need a different software now?

BMW Group Rectification Programs UK is the INPA program that was/is used at the Goodwood and Cowley plants. Don’t worry about it too much, as the only real differences between the two, are the size of the dynamic link libraries (something that i doubt will effect what you want to do with it).

If you have a PCMCIA port on your laptop, you can buy cards that can be set-up to have access to the 03F8-03FF address as COM1, and as such can be used with an ADS interface. (Note: There are USB Ediabas interfaces that have L-Line available on Pin-15 of the J1962M socket, and this can therefore be passed through an adaptor to Pin-15 on the 20-pin ADS socket - they are very rare and very expensive though - not really suitable for guys doing this as a hobby.)
Can I still use this software, or do I need a different software now?
As long as your software has the ADS set-up files, you will be okay. Look in C:\Ediabas\Hardware\ADS

Unfortunately this guide is only tested with the USB interface specified, but let us know how you get on - could you click the Thumbs Up icon bottom left of the original article? I'm still trying to get this article 'stickied' by the mods are ignoring me...

Given it the thumbs up :)

Got it hooked up with the vagcom cable, managed to read fault codes ok, saw lots of communications errors when trying to interogate anything other than the engine ecu though.
I had one error only, what does the shadow memory mean, there were 4 errors within that bit?

Not entirely sure of the difference, FAL will hopefully help with this question :D

My understanding is that it’s used for warranty claims and recalls - usually only readable/clearable with factory/developer software tools and not dealer/3rd party software tools.

The software supplied with the cable didn't seem to be complete and so I chose instead to find a trusted source of the software. The two links that I have provided are all that you need, although I'm not saying that it's impossible to get it working using the supplied software.

Gordon, have you followed the instructions with regards to how to install the cable? It is also important to always insert the cable back into the same USB port else it won't work. Try this, insert the cable into your laptop, then go into Control Panel -> System -> Device Manager and look for 'Unknown Devices', if you can find one, double-click the entry, click 'Update Driver' and then browse to the folder containing the driver (this is included on the CD that ships with the cable).
