VAG Dash K+CAN troubleshooting

[alexs307]

Hi. I recently bought a Chinese clone of VAG Dash K+CAN, but I can't get it to work.

First, I followed the installation procedure that came with the software CD, version 4.22. I installed the application, leaving the interface not connected, after installation completed, I plugged the usb connector and installed the drivers from the software CD. - no result, interface not working, it says "trying to connect" and after a while it says "connection time out".

Second, I followed the installation procedure on the supplier's website: I uninstalled previous version of VAGDASH, plugged the USB connector first, installed the driver from USB directory on software CD, after that I installed the program - result ok, I managed to connect to a EDC16 Passat and modified mileage. Atfter that, on second try, the interface didn't work - same "trying to connect/connection time out" error.

Third, I searched for a newer version of program, not original, I found 5.05, installed both ways but still no result.

Fourth, I uninstalled version 5.05, installed 4.22 back and succeded in connecting again to the tacho of same Passat, but got a "communication lost" error and wasn't able to modify tacho mileage again. The interface isn't broken, in device manager it appears as it should do: "VAG Dash K+CAN device" in USB ports. The Passat is B6 and it is mine, I use it for test.

Fifth, I checked the cable between bluebox and OBD port, there are some pins that don't have continuity from little connector on bluebox to OBD connector. I don't know the pinout of this cable, maybe someone can point to a schematics.

Can anyone help me? Does anyone have a software that is sure to work on these kind of clones? The supplier told me that this interface is very hard to burn, so I must reinstall the software several times until I get it to work if I encounter errors doing that.

Help!
