This article will guide you how to install VAG-COM 12.12 USB cable on Windows and VCDS software. (This article also applies to newer versions like VCDS 14)

CAUTION:

There's several versions of VAG-COM 12.12 sold online. Unfortunately 99% of them are using low-grade hardware chip with additional of cracked VCDS software (sometimes needed an awkward computer date adjustment). If you own this kind of version, know half of it's functions don't work. For that reason we recommend you get the high-quality VAG-COM 2016 cable with original, unlocked and full version of VCDS software from Ross-Tech™ — by clicking here.

 

STEP 1: Install Ross-Tech VCDS Software

DO NOT plug VAG-COM cable into computer yet.

Install VCDS software.

Leave original installation path of: C:\Ross-Tech\VCDS

When software has installed, restart computer. Then go to Step 2 below...

 

STEP 2: Plug VAG-COM Cable Into Computer

FIRST disconnect from internet/WIFI.

Plug VAGCOM cable into any USB port.

Let Windows automatically install drivers.

VAGCOM If Windows says that drivers are successfully installed, then continue to Step 3 below.

VAG-COM 12.12 USB If Windows fails to install drivers, then can skip to Troubleshooting below.

 

STEP 3: Disable Internet & Launch Software

GOLDEN RULE TO APPLY EVERTIME BEFORE USING VAGCOM: Connect VAGCOM cable to computer and car before launching VCDS software. And have internet/WIFI turned off before launching VCDS software.

Have you read and applied the GOLDEN RULE above? If yes, then...

Launch VCDS software from Start Menu. Or from C:\Ross-Tech\VCDS\VCDS.exe

Go to: Options » Test (leave it as USB)

It should show "Interface Found", as seen below...

Click "Save". You're now ready to scan your car.

 

 

Troubleshooting:

You are here because when you inserted VAG-COM cable for first time, Windows failed to install drivers properly.

 

SOLUTION 1:

Leave cable connected to computer. Restart computer. It should be fixed now. Go to Step 3.

 

SOLUTION 2:

VAGCOM cable should be connected to computer.

1) Go to Control Panel.

  • Windows Vista/7/8/10: Control Panel » System » Device Manager
  • Windows XP: Control Panel » System » "Hardware" tab » Device Manager

 

2) Expand "Ports (COM & LPT)" or "Universal Serial Bus Controllers".

You're looking for a device that has name "Ross-Tech" in it. It will have a yellow mark next to it like this: ross-tech install problem

Here's an example:   ross-tech-direct-usb-interface-device-manager-error-driverOR  it may show as "Ross-Tech Direct USB Interface".

 

3) Right-click on this device with the yellow mark » Update Driver Software.

4) Choose "Browse Computer for Driver Software".

5) Browse to: "C:\Ross-Tech\VCDS". It should look like this:

vag-com-ross-tech-driver-installation-windows

6) Click "Next". When you get below message, choose "Install this driver software anyway".

When driver installation is complete, disconnect cable from computer. Restart computer.

When you're back in Windows, you may connect cable into computer, and go to Step 3.

 

SOLUTION 3 :

If after SOLUTION 2, cable is still showing a Yellow mark (ross-tech install problem), then you're likely on Windows 8, 8.1, 10 or above.

In this case, disconnect cable.

And disable driver signature enforcement. Here's how: Windows 8/8.1  |  Windows 10

When done, go to Step 3.

 

Notes:

  • DO NOT update the software to latest version, else it will not work. Only works on current version.
  • If you bought your VAG-COM cable from us, then registration is not needed. It's already registered/licensed.
