Diagnostic connector Fitting location: below knee padding on left side of steering wheel

Selector lever lock solenoid -N110- Fitting location: the selector lever lock solenoid -N110--item 1- is located in the selector mechanism. The solenoid is integrated in the selector mechanism; it is therefore not possible to renew only the solenoid on its own. It can only be removed or installed together with the selector mechanism → Chapter.

Valve body Fitting location: the valve body is bolted to the underside of the gearbox housing and covered by the gearbox oil pan.

Multi-function switch -F125- Fitting location: the multi-function switch is located at the top of the gearbox. The connector -item 5- is plugged in directly on the multi-function switch.

tiptronic switch -F189- Fitting location: the tiptronic switch -F189- is integrated in the printed circuit -B- of the selector mechanism. The tiptronic switch -F189- is integrated in the selector mechanism; it is therefore not possible to renew only the switch on its own. It can only be removed or installed together with the selector mechanism → Chapter.

Starter inhibitor relay -J207- Fitting location: on the 13-position relay carrier → Current flow diagrams, Electrical fault finding and Fitting locations

Gearbox output speed sender -G195- Fitting location: the gearbox output speed sender -G195--arrow 2- is fixed to the gearbox housing behind the valve body.

Gearbox input speed sender -G182- Fitting location: the gearbox input speed sender -G182--arrow 1- is fixed to the gearbox housing behind the valve body.

Selector lever position indicator -Y6- Fitting location: integrated into instrument cluster   Note! The selector lever position indicator -Y6- can only be renewed together with instrument cluster.

Kickdown switch -F8- Vehicles with petrol engine are not equipped with this switch. Instead, the engine control unit stores a specific value obtained from the accelerator position sender -G79-/accelerator pedal position sender -2- -G185-.

Brake light switch -F- Fitting location: the brake light switch -F--arrow- is located on pedal cluster.   Note! Switch may only to be fitted once so as to ensure a firm fit.
