Shifter A/T: Testing and Inspection
Selector Mechanism, Checking
Selector mechanism function test
‹› In selector lever positions "S", "D", " R" and "Tiptronic gate" the starter motor will not operate.
‹› If selector lever position "N" is selected at speeds greater than 5 km/h, the selector lever lock solenoid must not engage and block the selector
lever. Selector lever can be shifted into driving 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. Selector lever can only be shifted out of position " N" with the brake pedal operated.
Selector lever in "P" position and ignition switched on:
-
Do not operate brake pedal.
‹› Selector lever is locked and cannot be shifted out of position " P" while locking button on selector lever handle is pressed. Shift Lock Solenoid
(N110) blocks selector lever.
-
Press brake pedal and hold.
‹› Shift Lock Solenoid (N110) releases selector lever. Selecting a driving mode is possible. With locking button on selector lever handle pressed,
slowly shift selector lever from "P" through " R, N, D, S"; when doing so, check whether Transmission Range (TR) Display (Y6) in instrument
cluster corresponds with selector lever position.
Selector lever in "N" position and ignition switched on:
-
Do not operate brake pedal.
‹› After a brief pause: Selector lever is locked and cannot be shifted out of "N" position despite pressing locking button on selector lever handle.
Shift Lock Solenoid (N110) blocks selector lever.
-
Operate brake pedal.
‹› Shift Lock Solenoid (N110) releases selector lever. Selection of position "D" is possible.
Selector lever in position "D", ignition switched on:
-
Shift selector lever into "Tiptronic gate".
‹› Lit "D" symbol in Selector Lever Transmission Range (TR) Position Display (Y26) must go out and " +" and "-" symbols must light up.
‹› The Transmission Range (TR) Display (Y6) in the instrument cluster should switch from "PRNDS" to " 654321" when the selector lever is shifted
into the "Tiptronic gate".
If the specified values are not obtained.
-
Adjust selector lever cable. Refer to => [ Selector Lever Cable, Adjusting ] See: Shift Linkage/Shift Cable/Adjustments.
