Hi All,

I have been trying to tap into my VW Can bus but been having a very hard time.

I first tried connecting through the OBD port but it seems that messages are filtered there.
I also tried the radio but I do not see anything when connecting to the quad lock connector.

Can someone point me in the right direction?


Hi Dog,

VW is using a CAN-Gateway. The OBD-Port is only connected to this gateway.
A direct connection to the does not exist.
If you like to hear messages from a control unit, you have to tell the gateway to foreward the messages to the OBD-Port. Up to now I have not figured out how to do so.

When you connect to the radio, depending on the year your car was build, you should be connected to the Infotainment-CAN.

Best regards,

What year and model VW? Most of the older VWs just use the OBD-II as a diagnostic port only. You can scan for errors and code modules, but you won't see CAN traffic. There are a few places where you might be able to tap in.

Looks like your connection to CANBus Triple was lost, please wait while we try to reconnect.
