Hi guys, my name is Ygor and I'm developing some systems to get information from the CAN-BUS of the Audi A3 8L 1998-2006, I did some tests but I was not successful, I would like to know if anyone would have this information to help me.

What I need is the Protocol (code) sent by Can for ABS wheel speeds, so to develop a dash that shows the speeds by taking the information from the CAN-BUS, I know that by VCDS there is a way, but I didn't find the option

The wheel speed sensors do not communicate via CAN bus. They are much simpler sensors. The ABS module interprets these sensors and you can read the individual wheel speeds from the ABS module using VCDS.

However, I doubt that the ABS module in this car broadcasts the individual wheel speeds, in part because no other module in this car cares about the individual wheel speeds, and in part because MY 1998 and 1999 cars didn't have a CAN bus to broadcast them on.

Thus I do not think it is practical to do what you are proposing.
