- 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 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" , 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:

- Shift Lock Solenoid N110 releases selector lever. It is possible to shift into a driving gear. 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.

- 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 instrument cluster should switch from "PRNDS" to "654321" when selector lever is shifted into "Tiptronic gate".
If specified values are not obtained:
- Perform "Guided Fault Finding" with Vehicle Diagnosis, Testing and Information System VAS 5051B.
