Audi Comments:

1. A4 model 8E version B6
This model has a CAN bus-bar (TP1.6), but it is NOT connected with the diagnostics socket. The A4 model 8E version B6 can be fully diagnosed through dual K line (needs VCP+K ) using protocols KWP2000 and KWP1281.

2. A4 Model 8E, version B7 & Seat EXEO
This model has a CAN bus-bar (TP2.0). However, there is only a so called “CAN-Antrieb” connected with the diagnostics socket, which covers the engine, gear box, airbag, ABS, and Quattro drive. Additionally, it uses a dual K line. In other words, VCP fully supports diagnosis of B7 model but ONLY in the range of CAN-Antrieb (engine, gear box, airbag, abs, Quattro drive). All other drivers are available through K line (protocols KWP2000 i KWP1281) Simply, VCP + K line is needed.

Key status is displayed on the bottom bar of the VCP program and in the Activator window after connecting with the server. Key recharge is and will be free of charge. This solution is related to the security of the system and allows us to locate unauthorized users in case of computer theft. User registration data is assigned to the key and the server update. If you need to change your registration data, please contact the dealer from whom you purchased the system.


The firmware interface update procedure is described in the INSTALLATION section.
We would like to remind you that manual firmware updates are available only for K+CAN interfaces (label on the interface: VCP+K). CAN interfaces (label on the interface: VAG CAN PRO) are not updated using the Activator program.


1. Updates are free for a period of twelve months from the date of the purchase of the system.  However, lack of the latest update will not affect the functioning of the device!

2. SPECIAL UPDATES allow the system user to access unique upgrade offers which extends the functionality of the system software. SPECIAL UPDATES OFFERS supports cars made by companies different from the VW group, such as OPEL, FIAT, and RENAULT. There are also unique functions that are classified beyond the traditional notion of car diagnosis. For example, the validation of the mileage in the VW group cars based on drivers other than the mileage meter and the engine driver. These updates will require an additional fee – in some cases, the special update activation will necessitate the replacement of the USB Key (dongle). The availability of such updates will be announced.

Is Linux compatible with VAG CAN PRO?


When I try to connect to the server, the “No authorization to connect” message is displayed.

The Key is not authorized by the seller (dealer). Please contact your seller (dealer).

The program does not start. What should I do?

 Are you sure you made the installation and update in accordance with the instructions given on this website?

A customer came in with a VW Passat 3C to replace the rear brake pads. I took the clamps back using the OCF function, but they stepped aside too little and pads do not fit. What should I do?

The client waited too long to replace the pads and as a result, they have been used up to the limit. After the withdrawal of the clamps (using OCF), push the piston into the cylinder deeper mechanically.

My connection between the VCP program and the vehicle is unstable. The program displays incomplete driver data or breaks the connection. What should I do?

The program has a special diagnostic mode which enables individual selection of settings for the system based on the user’s computer log analysis. You should:
1. Run the VCP software.
2. Press the following buttons at the same time: CTRL + SHIFT + ALT + D, a debugger window will open.
3. Tick the login boxes in the debugger. (Login to file and communication login)
4. Minimize the debugger window. (do NOT exit)
5. Try to diagnose the driver creating problems from the level of VCP.
6. Close the debugger.
7. Send an email to Revtronic with the generated log from the directory on drive C:\cancomm_log

I cannot install the VCP on Windows Vista. The program does not load.

 Ensure that during the installation, you have conducted every step in accordance with steps and conditions listed on the website:
Installing on VISTA, 7
VCP is fully compatible with MS Windows Vista, MS Windows 7 and it is marked with the logo “Certified for Windows Vista”. However, in order to install the program properly and to be able to download the updates, be aware of four things:
1. The user who installs the VCP MUST possess administrative rights in the Operating System (MS Windows Vista or MS Windows 7).
2. The “User Account Control” function must be disabled.
3. VCP should be installed outside the “Program Files” folder and in a separate folder (e.g. “C:\VCP”).
4. While downloading, any antivirus control should be disabled.

I cannot connect with the activation server. What is wrong?

Most likely, a poor internet connection is responsible, especially when a GSM provider is used to establish connections (even UMTS). You should also make sure that:
– You have the current version of the Activator program.
– There are libraries: libeay32.dll and ssleay32.dll located in the catalogue of the Activator program.
