Selector Mechanism, Checking

Overview:

• 1. Selector mechanism function test

• 2. Check the ignition key lock

• 3. Check the closing locks

• 4. Selector Lever Handle Locking Button, Checking

1. Selector Mechanism Function Test

• The starter may not be activated in the "S", "D" or in "D/S", "R" and "Tiptronic gate" selector lever positions.

• 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 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.

- To reach the "ignition on" position, press the ignition key briefly in the ignition lock or quickly press the access/start authorization button (E408).

- 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 or D/S". While doing this, make sure the transmission range display (Y6) inside the instrument cluster matches the actual position of the selector lever.

Vehicles from MY 2012

- 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 must change from "D" to "S1" in the instrument cluster and then go back to "D" after pulling the lever toward the rear.

All Vehicles

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 locks the selector lever.

- Press the brake pedal.

• The shift lock solenoid unlocks the selector lever. It is possible to shift into the "D" or "D/S" shifting positions.

The selector lever is shifted into the "D" or "D/S" position, ignition is turned on:

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

• The illuminated "D" or "D/S" (symbols in the selector lever transmission range position display unit (Y26) ) must turn off and the "+" and "-" symbols must turn on.

• The transmission range display inside the instrument cluster must change from "D" to "M1" when the selector lever moves into the "tiptronic gate"

- Press Guided Fault Finding on the vehicle diagnostic tester if the specified value is not reached.

- Adjust the selector lever cable. Refer to => [ Selector Lever cable, Adjusting ] Adjustments.

- Locking button on selector lever handle, checking.

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, Adjusting ] Adjustments.

- Locking button on selector lever handle, checking.

2. Check the Ignition Key Lock.

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

- Do not press the brake pedal.

- Press the key briefly in the ignition lock to reach the "ignition on" position.

- Press the brake pedal and hold it down.

• It must be possible to move the selector lever out of "P" without "getting stuck" when the locking button in the selector lever handle is pressed.

- Turn off the ignition.

• It should not be possible to remove the ignition key when the selector lever is in any other position than "P".

- Move the selector lever into "P".

- Remove the key.

• It should be possible to remove the key only when the selector lever is in "P".

• The selector lever does not move out of "P" even though both the locking button and the brake pedal are pressed.

Select Guided Fault Finding on the vehicle diagnostic tester if the key lock does not function as described.

3. Check the Closing Locks - Vehicles with Keyless Stop and Start Systems

- Press the access/start authorization button (E408) briefly to get "ignition on".

- 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.

- Turn on the ignition, shift the selector lever into the "P" position.

- 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, Adjusting ] Adjustments.

- Locking button on selector lever handle, checking.

4. Check Locking Button in the Selector Lever Handle

Make sure locking button moves easily.

• It must be possible to press the locking button without using great force.

• After releasing, the locking button must come all the way back out by itself.

- Check the selector lever handle for correct installation if the specified values are not reached => [ Selector Lever Handle, through MY 2011 without RS5 ] Selector Lever Handle, Through MY 2011 Without RS5.

- Make sure the selector lever is not bent.

Function test:

• The ignition is switched on.

The locking button on the selector lever handle must be pressed for the following shifts. If it is not pressed, the selector lever cannot be shifted into the specified position.

• Move the selector lever from "P" into "R" and press the brake pedal at the same time.

• Only vehicles through MY 2011: "D" into "S"

• "N" into "R"; stationary, press the brake pedal after waiting longer

• "R" into "P"

If the specified values are not obtained:

- Make sure the selector lever handle is installed correctly. Refer to => [ Selector Lever Handle, through MY 2011 without RS5 ] Selector Lever Handle, Through MY 2011 Without RS5.

- Check the connectors on the selector mechanism.

- Perform Guided Fault Finding using the vehicle diagnostic tester and check the shift lock solenoid.

- Adjust the selector lever cable. Refer to => [ Selector Lever cable, Adjusting ] Adjustments.
