1. Selector Mechanism Functionality Test Refer to GEARSHIFT MECHANISM, CHECKING .

The starter does not work when the selector lever is in "S", "D", "R" or in the "tiptronic gate".
If selector lever position "N" is selected at speeds greater than 5 km/h, the shift lock solenoid must not engage and block the selector lever. The selector lever can be moved into a another gear.
For speeds below 2 km/h (almost standstill) and shifting into selector lever position "N", the shift lock solenoid must only engage after approximately 1 second. The selector lever can be move out of "N" only when the brake pedal is pressed.

Selector lever in "P" and the Ignition Turned On:

-- Do not press the brake pedal.

The selector lever is locked and cannot be moved out of "P" while locking button on selector lever handle is pressed. The Shift Lock Solenoid -N110- locks the selector lever.

-- Press the brake pedal and hold it down.

The Shift Lock Solenoid -N110- unlocks the selector lever. It is possible to shift into a gear. Press the locking button in the selector lever handle and slowly move the selector lever out of "P" through "R, N, D, S". While doing this, make sure the Transmission Range Display -Y6- inside the instrument cluster matches the actual position of the selector lever.

The Selector Lever Is in "N" and the Ignition is Turned On:

-- Do not press the brake pedal.

After a brief moment: The selector lever is locked and cannot be moved out of "N" even though the locking button in the selector lever handle is pressed. The Shift Lock Solenoid -N110- locks the selector lever.

-- Press the brake pedal.

The Shift Lock Solenoid -N110- unlocks the selector lever. It is possible to shift into "D".

Selector Lever in "D" and the Ignition is On:

-- Move the selector lever into the "tiptronic gate".

The "D" in the Selector Lever Transmission Range Position Display Unit -Y26- must turn off and the "+" and "-" must turn on.
The Transmission Range Display -Y6- in the instrument cluster must change from "D1" to "M1" when the selector lever is moved into the "tiptronic gate".

NOTE:

"M1" for manual Tiptronic, 1st gear.

If the specified values are not obtained:

-- Locking button on selector lever handle, checking. Refer to GEARSHIFT MECHANISM, CHECKING .

-- Refer to SELECTOR LEVER CABLE, ADJUSTING .

-- Check the ignition key lock. Refer to GEARSHIFT MECHANISM, CHECKING .

2. Ignition Key Lock, Checking Refer to GEARSHIFT MECHANISM, CHECKING .

-- Turn the key to the right to the "ignition on" position.
