Automatic transmission selector position indicator "Y6"

The "Y6" automatic transmission selector position indicator is integrated into the instrument cluster. If the automatic transmission selector position indicator is faulty, the instrument cluster must be changed.
Selector Lever Sensor Control Unit "J587"
The gear selector sensor control unit "J587" "pos. 2" is attached to the functional unit of the "arrow" shift mechanism.
Selector lock solenoid "N110"
The automatic transmission selector lock magnet "N110" "Pos. 1" is fixed with clamps on the gear shift mechanism.
Selector position switch P "F305"

Installation location: The selector position switch "F305", consisting of two reed switches "1" and "2", is mounted on the "B" board of the automatic transmission selector lock solenoid "N110" "pos. A". The selector position switch "F305" can only be replaced together with the automatic transmission selector lock solenoid "N110". Depending on the design, various versions and installation locations are available.
Oil temperature sensor 2 "G754"

For certain engine variants, an additional system is installed on the 7-speed manual transmission with dual clutch 0B5 (S tronic). oil Temperature Sensor 2 "G754" for monitoring the gear oil temperature (MTF oil). Installation location: Oil Temperature Sensor 2 "G754" is screwed in the oil area. pallet on the checkpoint. Depending on the design, there are various versions and installation locations.
Gear selector position indicator panel "Y26"
"Pos. 1" is fixed with clamps in the center console.
Kickdown switch "F8"

The engine control unit stores a specific value from the accelerator pedal position sensor "G79" and the accelerator pedal position sensor 2 "G185." Installation location: The accelerator pedal position sensors are integrated into the accelerator pedal module. If one accelerator pedal position sensor is faulty, the accelerator pedal module must be replaced.
