A6 V6-3.0L (AVK) (2004)
-
The engine speed in display zone 1 (actual speed) is the actual engine speed.
-
The engine speed in display zone 2 (specified speed) is a theoretical value calculated by the engine control module.
-
During idling, the engine control module always tries to adapt the actual engine speed to the specified engine speed.
-
This means that during idling the actual engine speed must always be approximate to the specified engine speed.
-
Display zones 3 and 4 are there for information but are irrelevant to the control of the engine idling speed.
-
Exit function "04 - Basic setting" by pressing <- button.
If specified value is not obtained:
-
Check Diagnostic Trouble Code (DTC) memory again.
-
If DTC memory was erased, readiness code must be re-generated.
Continued
If the idling speed is too high or too low and there are no DTCs recorded in the DTC memory, carry out the following tests:
-
Check intake air system for unmetered air.
-
Check throttle valve control module.
-
Check whether solenoid valve for Evaporative Emission (EVAP) canister purge regulator valve is continuously open.
-
Perform adaptation of throttle valve control module.
