1. Selector Mechanism Functionality Test

• Never operate the starter when the selector lever is in "R", "D/S" and the "tiptronic gate".
• If selector lever position "N" is selected at speeds greater than 5 km/h (3.1 mph), 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 (1.2 mph) (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 moved out of "N" only when the brake pedal is pressed.

Selector lever in "P" :

-- Press the button on the electro-mechanical parking brake to activate it.

-- Turn off the ignition.

• Selector lever is locked and cannot be shifted out of position "P" while locking button on selector lever handle is pressed.

-- Turn on the ignition.

-- Do not press the brake pedal.

• Selector lever is locked and cannot be shifted out of position "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 button in the selector lever handle and slowly move the selector lever from "P" and 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.

-- Pull the selector lever toward the rear out of "D/S" and then release it again.

• The selector lever moves automatically back into "D/S". The Transmission Range Display -Y6- must change from "D" to "S1" in the instrument cluster and then go back to "D" after pulling the lever toward the rear.

The selector lever is in "N" and the ignition is turned on:

-- Do not press the brake pedal.

• After a short waiting period: The selector lever is locked and cannot be moved out of "N" position despite pressing locking button on selector lever handle. 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/S".

The selector lever is in "D/S" and the ignition is on:

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

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

-- Do not move the selector lever into "P" but rather, for example, into "N".

-- Turn off the ignition.

• A warning message must appear in the instrument cluster.
• The vehicle cannot be locked.

-- Move the selector lever into "P".

-- Turn off the ignition.

• The vehicle can be locked.

If the specified values are not obtained:

-- Perform Guided Fault Finding  using the Vehicle Diagnostic Tester.

-- Adjust the selector lever cable. Refer to SELECTOR LEVER CABLE, CHECKING AND ADJUSTING .

-- Locking button on selector lever handle, checking. Refer to 2. Selector Lever Handle Locking Button, Checking .
