Diagnostic Mode 1: Obtain data
2009 Audi A6 BaseSECTION Diagnostic Mode 1: Obtain data
WARNING: This page is about a different car, the 2006 Audi A6 and 2005 Audi A6. However, it is still accessible from the selected car via links, so may be relevant.
In this diagnostic mode, all emissions-relevant measured values are displayed.
Test requirement
- Coolant temperature at least 80° C.
Procedure
- Connect diagnostic tester. → Diagnostic tester, connecting .
- In diagnostic function "address word 33 - OBD" select "Diagnostic Mode 1: Obtain data."
- Select desired measured value according to the "PID XX", e.g. "PID 05-Coolant temperature", via the following table.
NOTE:
- Specified values assigned to the measuring values are found in the corresponding component and function tests.
- Measuring values of the Engine Control Module (ECM) J623 are displayed under "10 - Engine electronics" and measuring values of Transmission Control Module (TCM) J217 are displayed under "1A - Transmission electronics".

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
