1) During road test: To read test equipment a second technician is needed.
2) The transmission is equipped with an automatic transmission range monitor. The forward range is displayed that the TOM would activate if a transmission range change would be made in selector lever position "D".
Note to display field 4, display group number 001:
^ Faulty solenoid valves or other DTCs can prevent certain transmission ranges to be activated.

Note to ATF temperature:
- A recognized temperature of minus 50°C (-58°F) is likely to be a short circuit to Ground (GND).
- A recognized temperature of 180°C (356°F) is likely to be a short circuit to plus (B+) or open circuit.

1) This display field is only displayed as of m. y. 2000 (May 1999).
Note to intermediate transmission ranges:
If the selector Lever is shifted into the shown intermediate positions, the VAG 1551 scan tool will display 'Z1", 'Z2", 'Z3" or 'Z4". In the instrument cluster display no selected transmission range may be displayed, meaning that only PRND432 is shown without a particular range illuminated.

Test requirements for torque converter slip numbers:
^ "Torque converter clutch closed": Shifting must be completed (wait at least 1 second), the torque converter clutch must be closed and the accelerator pedal value must be steady.
^ "Torque converter clutch adaptation": The values shown apply to the "adapted condition" of the torque converter clutch. Under unfavorable conditions (for instance acceleration on a hilly this condition is reached only after 20 seconds after completed shifting. During this adaptation phase slip values of up to 350 RPM can be reached.
^ Torque converter slip numbers that are too high can also indicate a slipping clutch or not activated shift elements.

1) During road test: To read test equipment a second technician is needed.
Note to Display field 1 and 2:
When kickdown is activated, display field 2 must also indicate 100%.
Display group number 009
1) During road test: To read test equipment a second technician is needed.
2) During driving with a transmission range engaged, the displayed shift moment is always high since no engine reduction is necessary.
Note to display field 1:
The signal for the engine moment is transmitted by the Engine Control Module (ECM) via the CAN-Bus wiring.
