WARNING: This page is about a different car, the 2007 Audi A4, 2006 Audi A4, and 2005 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostic Mode 01 is used to display and monitor all emissions related measured values.
Test requirement
- Coolant temperature at least 80°C.
Procedure
- Connect the diagnostic tester.
- Start the engine and run at idle.
- Select "Diagnostic Mode 1: Obtain data.".
- From the following table, select the desired the "PID" that is to be monitored, e.g. "PID 05-Coolant temperature".
NOTE:
- More than one "PID" may be selected and monitored.
The current values of the component or system that is being monitored will be displayed on the diagnostic tester screen.
