Which signals does the Audi A2 OBD-II port transmit?

I am trying to understand the OBD-II port on the Audi A2 and which signals it transmits. Can anyone provide me with a list of these signals and their corresponding codes?

The Audi A2 OBD-II port transmits various signals including engine speed, vehicle speed, throttle position, and coolant temperature. These signals can be read using an OBD-II scanner. A list of the codes and their corresponding signals can be found in the vehicle's service manual.

In addition to the standard signals, the Audi A2 OBD-II port also transmits manufacturer-specific signals such as oxygen sensor data, fuel system status, and misfire detection. It's important to use a scanner that can read these specialized codes in order to fully diagnose any issues with the vehicle.
