Test requirement:

Engine not running, ignition switched on.

Display on VAS5051:
Note:
There will be a prompt: "Operate kick down".
Note:
During adaptation of the kick down point, "Kick down ADP in progress" will
be indicated in display. After successful adaptation of the kick down point,
"Kick down ADP OK" will be indicated on display. -
Press button 3 times to change into display group 063.- Depress accelerator pedal completely, past kick down point, and hold

Note for display field 4:
"ERROR" can be indicated, for example, if the accelerator pedal is not immediately pressed in response to a request by the
tester or if the accelerator pedal is released while adaptation is running despite the fact that adaptation is not yet complete. In
both cases, "Basic Setting" must be exited and the adaptation must be performed again.

Work step 5: Check operating condition of
oxygen sensor control

- Start engine (for a vehicle with manual
transmission: engage clutch).

Note:
If necessary, vehicle system "01 - engine
electronics" and diagnostic function "04 -basic
setting" must be selected again after engine
start.

- Install VAG1788/10 RPM adjuster on the
accelerator pedal and raise the engine speed to
2600 RPM.

Test requirement:

Engine running at 2600 RPM.

Notes:

The first position of the 3 digit indication (heating) fluctuates between 0 and 1 at certain operation points.
Oxygen sensor control of oxygen sensor behind catalytic converter (bank 1, sensor 2) is not active without engine load,
meaning that the third position of the 3-digit display is 0.
