Shifter CVT: Procedures
Shift Mechanism (From VIN 8E_6A156500), Checking
Shift mechanism (from VIN 8E_6A156500), checking - 01J, Continuously Variable Transmission (CVT)
Overview:
^ 1. Selector mechanism function test
^ 2. Checking ignition key removal lock
^ 3. Locking button on selector lever handle, checking
-
If shift mechanism does not function as described, perform "Guided Fault Finding" with Vehicle Diagnosis, Testing and Information System VAS
5051B.
1. Selector mechanism function test
^
In selector lever positions "S", "D", "R" and "Tiptronic gate" starter motor will not operate.
^
If selector lever position "N" is selected at speeds greater than 5 km/h, selector lever lock solenoid must not engage and block 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 approx. 1
second. Selector lever can only be shifted out of position "N" with brake pedal operated.
Selector lever in "P" position and ignition switched on:
-
Do not operate brake pedal.
^
Selector lever is locked and also 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. It must be possible to select a driving mode without "hitching" while locking button on selector
lever handle is pressed.
^
Slowly shift selector lever from "P" through "R, N, D, S", checking whether Transmission Range (TR) Display Y6 in instrument cluster matches
selector lever position.
Selector lever in "N" position and ignition switched on:
-
Do not operate brake pedal.
^
Selector lever is not locked immediately when rapidly shifting through position "N" (e.g. from "R" to "D" ). This enables e.g. "forward and reverse
maneuvers" when vehicle is stuck. Shift lock engages when selector lever is located in "N" for longer than approx. 1 s with brake not being
pressed.
-
Operate brake pedal.
^
Shift Lock Solenoid N110 releases selector lever. It must be possible to select a driving mode without "hitching" while locking button on selector
lever handle is pressed.
Selector lever in position "D", ignition switched on:
-
Shift selector lever into "Tiptronic gate".
^
Brightening of "D" symbol must go out in selector mechanism cover and "+" and "-" symbols must light up.
^
The Transmission Range (TR) Display Y6 in instrument cluster should switch from "PRNDS" to "7654321" when selector lever is shifted into
"Tiptronic gate".
If specified values are not obtained:
-
Adjust selector lever cable.
-
Check ignition key removal lock.
2. Check ignition key withdrawal lock
-
Switch ignition key to driving position ( "ignition on" ).
-
Press brake pedal and hold.
^
It must be possible to shift selector lever out of position "P" without "hitching" while locking button on selector lever handle is pressed.
-
Switch ignition off.
^
It should not be possible to remove ignition key when selector lever is in any other position than "P".
-
Place selector lever in position "P".
^
It must be possible to move ignition key into removal position without "sticking".
-
Remove ignition key.
^
It must be possible to remove ignition key only in position "P".
^
Selector lever cannot be shifted out of position "P" with locking button pressed and parking brake operated.
3. Check locking button on selector lever handle
Check locking button for ease of movement:
^
It must be possible to press locking button without great force.
^
After releasing, locking button must come all the way back out by itself
