Description of measured value blocks, Audi A6 2005> 2.4l/4V MPI KNotes:
The engine speed is displayed on the tester only in increments of 40 in the lower measured value blocks.
J Idling speed specifications:
Ignition timing angle: 0 °CA ... 25 °CA b.TDC
J Coolant temperature readout with VAS 5051 / 5052 :
Absolute: - 40.5 °C ... +135 °C
Engine warmed up: + 80 °C ... +110 °C
Sensor defect: Substitute value (not constant)
J Intake air temperature readout with VAS 5051 / 5052 :
Absolute: - 40.5 °C ... +135 °C
Engine warmed up: Current ambient temp. < +80°C (max. +110°C)
Sensor defect: Constant + 20 °C (substitute value)

Test knock sensors
– Function 04 (basic setting)
- Activate short trip with button "4" (ON)
- Press brake pedal and at same time press accelerator pedal down fully: Engine speed automatically adjusts to 2200 rpm -> "Test ON"
- Wait for "Syst. OK" to be reached in the 4th field
