Actual Values: Notes

Values present at the moment of the test can be read out with this menu item.

It is possible to use a filter function to select certain actual values only. In this case, not all actual values are available for selection.

Press F5 key.

The following predetermined filters then appear:

• Engine values
• Oxygen sensing, bank 1
• Oxygen sensing, bank 2
• Misfire detection
• Knock control
• Throttle jacking unit
• Analog/digital converter
• TWC conversion
• Fuel tank ventilation
• Basic mixture adaptation
• Oxygen sensor, bank 1
• Oxygen sensor, bank 2
• Demonstration filter

It is now possible to create your own filters in this menu item.

Press F5 key.

Select required actual values and press double arrow key (>>). A field then appears where the name of the filter can be entered.

Enter the filter name and confirm. The newly created filter then appears in the selection list. Filters you have created can be deleted or changed.

The following values can be called up:

• Engine speed
• Engine load
• Actual engine torque
• Ambient pressure
• Mass air flow (HFM)

  [mass air flow without fuel tank ventilation]

• Altitude correction factor
• Power supply
• Intake air temperature
• Engine temperature
• Engine compartment temperature
• Oil temperature
• Catalytic converter temperature

  [value calculated by control module]

• Ignition angle
• Specified rpm
• Idle loss adaptation
• Injection time
• Camshaft position 1 deviation [adapted value -->
• Camshaft position 2 deviation [adapted value -->
• Actual angle for camshaft, bank 1

  [the function of the VarioCam can be checked with the actual angle]

  VarioCam not switched on --> display app. 0° crk

  VarioCam switched on --> display app. 25° crk]

• Actual angle for camshaft, bank 2

  [the function of the VarioCam can be checked with the actual angle]

  VarioCam not switched on --> display app. 0° crk

  VarioCam switched on --> display app. 25° crk]

• Mass air flow

  [mass air flow with fuel tank ventilation]

• EVAP canister burden

  [value range 0 to 30 0 - EVAP canister empty 30 - EVAP canister full]

• Oxygen sensing, bank 1

  [lower and upper load range --> displays the value currently travelled]

• Adaption, range 1 (RKAT), bank 1

  [range close to idle]

• Rel. fuel quantity, tank ventilation, bank 1

  [deviation from the anticipatory control due to fuel tank ventilation]

• Oxygen sensor voltage ahead of catalytic converter, bank 1
• Oxygen sensor voltage behind catalytic converter, bank 1
• Regulator delay behind catalytic converter, bank 1
• Sensor-signal period ah. of cat. c., bank 1

  [period greater than 2.3 or 3 seconds --> oxygen sensor faulty]

• Oxygen sensor resistance ahead of catalytic converter, bank 1

  [the resistance must be approx. 100 ohms after 3 or 4 minutes of travel.] Since the increments are in steps of 64 ohms (increase in value of 64 ohms), the tester reads 64 or 128 ohms. If, on the other hand, the display is in the k/ohms range (more than 1000 ohms), the oxygen sensor heating is faulty.]

• Oxygen sensor resistance behind catalytic converter, bank 1

  [the resistance must be approx. 100 ohms after 3 or 4 minutes of travel.] Since the increments are in steps of 64 ohms (increase in value of 64 ohms), the tester reads 64 or 128 ohms. If, on the other hand, the display is in the k/ohms range (more than 1000 ohms), the oxygen sensor heating is faulty.]

• Oxygen sensing, bank 2
• Adaption, range 2 (FRA), bank 2

  [lower and upper load range --> displays the value currently travelled]

• Adaption, range 1 (RKAT), bank 2

  [range close to idle]

• Rel. fuel quantity, tank ventilation, bank 2

  [deviation from the anticipatory control due to fuel tank ventilation]

• Oxygen sensor voltage ahead of catalytic converter, bank 2
• Oxygen sensor voltage behind catalytic converter, bank 2
• Regulator delay behind catalytic converter, bank 2
• Sensor-signal period ahead of catalytic converter, bank 2

• Oxygen sensor resistance after catalytic converter, bank 2

  [the resistance must be approx. 100 --> after 3 or 4 minutes of travel.] Since the increments are in steps of 64 ohms (increase in value of 64 ohms), the tester reads 64 or 128 ohms. If, on the other hand, the display is in the k/ohms range (more than 1000 ohms), the oxygen sensor heating is faulty.]
