-==== Special Tools ====
+<sup>1</sup> 17 – Instruments: Cluster, warnings, service interval
-* VCDS (VAG-COM Diagnostic System)
+<sup>2</sup> 5F – Infotainment / Information Control Unit
+<sup>3</sup> 19 – CAN Gateway with SFD2 diagnostic filter
-==== Prerequisites ====
-* Engine must be running
-* All electrical consumers OFF (A/C, headlights, rear defrost, seat heaters, etc.)
-* No active Diagnostic Trouble Codes (DTCs) – Clear all fault codes prior to starting the test
-* Engine coolant temperature must be at least 80°C (176°F)
-* <span style="color:red;">Must be performed outside or in a well vented area only!</span>
-==== Workshop Procedure with VCDS ====
-* Connect to the vehicle using VCDS.
-* Go to '''[01 - Engine]'''
-* Check for and clear any fault codes.
-* Click on the '''[Basic Settings]''' button.
-* Select '''[Automatic test sequence]''' or '''[Automatic test procedure]''' from the available list.
-* Click on the '''[Show Measuring Data]''' checkbox and include the following Measuring Values:
-  {| class="wikitable"
-  |-
-  ! Measuring Value !! Description
-  |-
-  | IDE00450 || '''Operating Instructions''' – ''Follow all prompts provided here''
-  |-
-  | IDE00451 || '''Currently Running Routine''' – ''Indicates the test currently in progress''
-  |-
-  | IDE00030 || '''Status of Actuator Test''' – ''Displays overall status of test procedure''
-  |-
-  | IDE00727 || '''Test Steps Still to Be Performed''' – ''Should count down to 0 when complete''
-  |-
-  | IDE00021 || '''Engine Speed''' – ''Follow any required RPM prompts shown in Operating Instructions''
-  |-
-  | IDE00025 || '''Coolant Temperature''' – ''Should be at or above 80°C before beginning''
-  |}
-* Click the '''[Go]''' button to begin the Basic Setting procedure.
-* When prompted, '''press and hold both the brake and accelerator pedals simultaneously.''' Keep them pressed until the test finishes.
-* When the test completes successfully, the '''IDE00450 [Operating Instructions]''' field will display:
-  ''''System OK''''   or   ''''Finished correctly''''
-==== Special Notes ====
-# The duration of the Automatic Test Sequence may vary depending on vehicle platform and engine type.
-# If the sequence fails or does not complete, verify that all prerequisites are met, especially coolant temperature and fault-free status.
-# This function is only available in UDS-based engine control modules. Non-UDS controllers use a different Readiness procedure, see Repair Manual.
-# If the [Go] button is grayed out or unavailable, ensure that the engine is running and that the selected test is supported by the ECU.
