Modify BMW USB-OBD Cable for 2005 and Later Cars

If you have an older USB-OBD diagnostic cable that works with BMWs up to 2005 [DIS v44 etc.] then it will need modifying to use with later cars and version of DIS / INPA etc. The process it pretty easy.

1. Remove the four screws from the OBD section of the cable using a crosshead-screwdriver.

2. The case will likely be glued together, so pry it open with a flat-screwdriver and remove the circuit-board.

3. Locate pins 7 and 8 on the back of the OBD-plug itself, which you will find bridged by a blob of solder. [Usually the right-side two pins looking at the face of the board with the LED on.]

4. Use a soldering iron to melt the solder between the two pins so they are no longer linked. [A solder-sucking device is useful here, but it can be pulled off onto the soldering-iron quite easily.]

5. Re-assemble circuit-board in casing and replace screws.

The cable will now work 2005 and later BMW cars, including newer models for all diagnostics using this interface, inc. DIS v55, v57, INPA 6.4.3 etc.

The cable will no longer work with BMWs made before 2005 and DIS v44, so it might be worth getting a spare cable to de-solder. The ideal solution is to solder small wires to each pin that run off to a switch mounted in the edge of the casing. cn555ic has done a very good guide on how to do this on E90post.com - https://www.e90post.com/forums/showthread.php?t=672940.

DIS v57 + INPA / EDIABAS 6.4.3 Installation + Guide

Download Links [MediaFire]:

BMW INPA / EDIABAS 6.4.3 + Install Files etc. [1.1GB]

BMW DIS v57 / SSS v32 Installer Files [6.7GB]

**You will need BOTH parts to fully install DIS v57**

You will need a laptop with USB running Windows XP or Windows 7.

You will need a USB-OBD cable optimised for post-2005 BMWs. An older cable can be modified by removing the solder-bridge between OBD pins 7 and 8 - a guide is here.

GUIDE:

Unpacking Files:

• Unpack the 2 .rar files into a new folder.
• Where the contained instruction file mentions unpacking files from CD1 and CD2, all the .rar files for both CDs are contained in the one 6.7GB download.  

Installation:

• If upgrading from DIS v44, install the files into the same folder and overwrite existing files.
• The instructions cover Windows XP, but files for Windows 7 and 64-bit, along with instructions for that are provided in a folder marked OTHER.

Further installation and troubleshooting instructions [getting the virtual machine / network bridge / ports etc. working] can be found in my prior DIS v44 guide: HERE.
