Diagnostic connection Fitting location: Cover in driver's footwell.

Selector lever lock solenoid -N110- Fitting location: Selector lever lock solenoid -N110--1- is located in the gearshift mechanism. The solenoid is installed firmly in the gearshift mechanism and cannot be replaced individually. The removal and installation procedure is only possible together with the gearshift mechanism → Chapter.

Slide valve body Fitting location: The slide valve body is bolted to the bottom of the gearbox housing and covered with the gearbox oil pan.

Wiring loom with 8-pin plug and integrated gearbox oil temperature sender -G93--Arrow- Fitting location: Wiring loom is fixed to the slide valve body.

Wiring loom with 14-pin plug Fitting location: Wiring loom is fixed to the slide valve body.

Multi-function switch -F125-

Fitting location: The multi-function switch is located at the top of the gearbox. The plug connection -5- is directly placed onto the multi-function switch.

Switch for Tiptronic -F189- Fitting location: The Tiptronic switch -F189- is integrated in the printed circuit board -B- of the gearshift mechanism. The Tiptronic switch -F189- is installed firmly in the gearshift mechanism and cannot be replaced individually. The removal and installation procedure is only possible together with the gearshift mechanism → Chapter.

Gearbox output r.p.m. sender -G195- Fitting location: The gearbox output r.p.m sender -G195--arrow 2- is fixed to the gearbox housing behind the slide valve body.

Gearbox input r.p.m. sender -G182- Fitting location: The gearbox input r.p.m sender -G182--arrow 1- is fixed to the gearbox housing behind the slide valve body.

Selector lever position indicator -Y6- Fitting location: Integrated in the dash panel insert.   Note The selector lever position indicator -Y6- can only be replaced together with the dash panel insert.

Kick-down switch -F8- This switch is not available for vehicles with petrol engine. Instead a certain value from the accelerator pedal position sender -G79-/accelerator pedal position sender 2 -G185- is stored in the engine control unit.

Brake light switch -F- ▶ 05.10 Fitting location: The brake light switch -F--arrow- is located in the foot controls.   Note The switch may only be installed once to ensure that it has an adequately tight fit.
