VCDS Interface Not Detected: Solutions for Original Cable & USB Driver Issues

Question

Hello.

I have a problem with VCDS.

DelphiCars and PolskiVAG work but VCDS won't work.
I have a dedicated original cable but there is a problem shown in the picture.

After installing the program on another computer, connecting the cable (windows recognizes and installs the drivers) the same error pops up.

The latest USB drivers from laptop manufacturers' websites.

Please help.

Then write to the manufacturer / seller. And they will definitely help.

The interface must be connected to the car (voltage 12V) otherwise it will not be detected.

I suggest not to speak up if you have no idea. The interface will be detected after connecting to USB. It does not need to be climbed in OBD. There will be a message that the interface has been detected, the type of interface and its status will be given - whether it is connected to the car or not. It's a bit weird that you have a dedicated cable and an old version of the program. It stinks a fake. Show what you can see in the device manager because from what you are writing you either have the wrong drivers or the Chinese has fallen out. Show what is the VID and PID in the manager. I hope you are not trying to fire up the Polish VAG on it. I do not know what the latest drivers are for and that laptop manufacturers' websites install themselves after the end of the program.

If you downloaded the software from the adako website, you need to connect the cable from adako or ROSS-TECHA and everything will work

A friend has rather an original from China, he installed a newer VCDS than what he got with the cable and the atmega162 went on vacation.

I will illuminate the situation brighter.

Car repair shop:
Quite old and old laptop + VCDS + cable = everything works

A repair shop employee has a cable at his disposal in the absence of the owner (and an old laptop).
So on another (newer and less old laptop) a VCDS was installed from the workshop owner board, a cable was plugged in and ... nothing. Mistake

After checking the cable on the owner's laptop, everything works.

Install VCDS from the manufacturer's website: If it still doesn't work then

The computer sees the interface before connecting it to OBD.
After connecting and trying to connect again, the error mentioned above pops up. Same situation for two cars (audi a6 and vectra b)

You did not follow the instructions above.

I'm not 100% sure because I can't reach that far with my memory, but from what I can see you have HEX-USB without CAN.
You are trying to connect to the car:

audi a6

and that tells us nothing. If it is A6 C6 4F or later, there is no K-line there anymore, everything goes on CAN.

Opel belongs to VAG ..?

DopieroZaczynam1 · Answer

Audi A6 C5 1998 with 1.8T AJL engine

I do not know if the Opel belongs to VAG. I just wanted to check if there is the same symptom in another car and that I have only one at my disposal at the time of "combining" it.

Temporarily, the subject of "I fall asleep" because I had to return the computer to the workshop, so for now, thank you for your commitment and all help. Next weekend I will have access to the computer again and I suspect a few cars because I will be at the workshop, then I will see if the same is happening on other vehicles.
