Here is obdii365.com customer DIY guide to make Vagcom Cable 409.1 modified to work with BMW INPA / SSS / ISTA-D / ISTA-P / DIS diagnostic software.

Note: This requires Good soldering skills and understanding. We are not responsible for the damage.

Standard 16-pin OBD PIN Please follow The Following steps: 1. First get a USB Vag 409 / vag-com 409.1 KKL cable (it is an old cable), ask the seller if it: has a FTDI FT232RL chip (FT232BM gold FT232BL Chips aussi work, but needs a bit more work). The FTDI chip supports software mods. 2. Download the driver http://www.ftdichip.com/Drivers/CDM/CDM%...tified.zip I prefer the driver 2.10.00 as the it-have newer drivers Given problems in some cases. Now unpack it, connect the cable, and installed with this driver.

3. Go To the advanced COM port settings and set for Com 9 if you are schedule to use BMW ICOM ISTA ISTA-D-P or whatever else you set the settings for Ediabas com. Also set to 1ms latency.

4. Open your vag cable casing and what you'll need to do is put a micro switch entre pins 7 and 8, so pin 7 and 8 pin can be shorted to be enabled for 09/2001 - 09/2006 cars, and disabled for newer cars, if you are only using the cable was older vehicle only you can bridge the connection by soldering together gold Then just leave em unconnected for newer vehicles.

5. These are the K lines on older vehicles, Otherwise you will not be ble to access to all modules of the car.

6. Now download MProg 3.5 http://www.ftdichip.com/Resources/Utilit...rog3.5.zip

7. If you do not want to do further Top Any soldering (RL Chip) you can run MProg, Otherwise jump to step 9. (If you-have a BM / BL chip please do step 8 And Then come back to this step) a. Go to Tools Menu -> Read and Parse Invert RI # and DSR # signals to fool the detection of battery and ignition, in order to be reliable to fool the software into thinking battery and ignition is fine. B. I / O Controls settings: # C0 = RXLED # C1 = TXLED # C2 = POWERON # C3 = PWRON # C4 = SLEEP

c. After making your changes: "Save Template as" (floppy green button, or File-> Save as ..) d. Program cable with the new settings: "Program" (Lightning button, or Device -> Program) e. These Settings are saved on the chip, so won't-have to be set every time. F. Cable aught to work now.

8. Do not do this step if you are going to go for real ingnition and battery option. If your vagcom comes with FT232BM / BL chip, you only need to do this extra work. Pin 17 is GND pin 18 is RI pin 20 is DSR So you need to solder pins 17,18 and 20 of the FTDI chip (this Applies to the BL and BM) like this.

BM and RL Chip Pinout

9. If you want some REAL battery and ignition detection, you will need The Following (For RL Chip) 1 x 4.7k ohm resistor 1 x 100k resistor (Higher is better) 1 x BC547B Transistor

10. For RL Only, Bridge PIN6 RI # Pin7 and GND, Then Pin9 DSR # BC547 is soldered to the leg with 4.7Kohm resistor, qui est in turn soldered to the second solder points on the cable side as in picture bellow, the middle leg of the transistor you connect inline with the 100k resistor to pin 1 of the odb the plug, and l'autre leg of the transistor is connected directly to pin 6 on the main pc board That connects to the odb connector. For RL chip you can now go to step 14.

RL Chip Pinout

(For BL / BM Chip) 1 x 100k resistor (Higher is better) 1 x BC547B Transistor

11. Bridge pins 17 and 18 of the FTDI (RL) chip - this will form a basis for the next step Then take the transistor, cut the legs So They are about 1cm long and the outer bend down and two together so there is about a 2mm gap entre em. Use the iron to dab a bit of solder on To Each of the three legs as peak bellow.

12. Now solder leg (E) to the bridged pins 17 and 18. If you've prepped well this will be simply a case of holding the transister Against the top of the FDTL chip, lining up the leg and dabbing it with the iron , Then check if the C leg is sitting over 20 pine (pine has there shoulds be That You AVOID entre les That Were two bridged). If it is not, bend it so it sits over it (Pin 20) And Then dab it with the iron. The solder That You put on the leg before shoulds be enough to get 'em to join. Keep going up to They Are stuck together.

13. Now take the resistor and one leg short cut (about 1.5cm). Then settle this leg to the middle 'B' pin of the transistor (the only one now not connected), Then bend the resistor so l'autre leg sits Against the back of pin 1 of the odb connector. and solder That one too.

14. Now Close the cover and you can now use the cable. (Remember if the DI # DSR # is inverted on the chips this software is not going to work).

If this does not work just check That You do not-have a fake chip, on the real chip is the writing etched into the chip, and the fake is only printed on.
