I bought BMW CarSoft v6.5 entire kit from China for less than 50USD including the shipping to Ireland. I am driving a BMW 1994 325i Coupe M50B25 Euro left hand drive.
Package including:
BMW 6.5 Interface Unit
BMW OBDI 20 Pin Cable
BMW OBDII 16 Pin Cable
RS-232 Serial (COM) cable
BMW CarSoft v6.5 software CD
Computer:
Attach the carsoft v6.5 interface to my old Win XP PC with COM port.
NOTE:
If your computer does not have a serial port, a PCMCIA serial card must be used.
A USB to Serial adaptor is not recommended and not supported in Carsoft.
A PCMCIA adaptor card is not included in Carsoft.
Please refer to the installation instructions that come with your PCMCIA Card.
Serial Port RS-232 on the PC/Laptop:
PCA RS-232 card inside:
Well let’s get right to it.
Carsoft v6.5 software was not difficult to install if follow the extremely detail pdf attachment here:

Mount on software image and enter into main menu
Click Perform Diagnosis->Total Diagnose, you will see lots of available tests control modules at once
Erase the fault codes in specific control modules
Click Special Functions tab, you are able to perform some special functions, like Live Data, LCM Reading, Service interval reset etc.
Live DME – Digital Petrol Engine Control Unit:
Viewing parameters: Engine speed (RPM), intake air temperature, air flow, power supply etc.
Live DDE – Digital Diesel Engine Control Unit:
twice more sensors and readings than DME.
Live EGS – Automatic Gear Box Control Unit:
Carsoft 6.5 erase DME code
No tool is perfect. Not all of those functions are available for all BMWs. Everything looks nice and promising, but… The newer BMW you have the more satisfaction you get from diagnose. I have OBDI and I couldn’t enjoy LIVE DATA and some other modules. If your model is 1994 later, it will be fine.
Tips for OBD2 car, if you get every modules not responding or DDE responding and all the other modules not responding.
Here is the solution. With the soldering iron, bridge the pin 7 and 8 (the 2 K-line) together
This will fix this problem on most E39 and E46
Another tip if you get a similar problem using a 20-pin on a 4-cylinder BMW try bridging the pin 17 and 20
BTW, if you have broken your CD like me, never mind, I got the free carsoft software driver
