Installation location: The tiptronic switch is integrated into the conductor
strip of the symbol insert in the cover of the shift mechanism.
Note:
This switch is not installed on shift mechanisms without tiptronic function.
The switch consists of 3 hall-effect sensors (-A-, -B-, -C- ), which are
activated via a magnet on the lateral gate cover of the gate cover. Fig. 9 Tiptronic switch -F189-

- If malfunctions occur, the switch for tiptronic
must be checked for interference in Read
measuring value block page 01

and
during the electrical test page 01

.

In case of problems, first check the magnet at the lateral gate cover -C- of
the gate cover is properly attached, replace gate cover, if necessary. Only
replace the symbol insert with integrated conductor strip after checking
the wires. For vehicles with tiptronic-sport steering wheel, also check the
buttons at steering wheel and their wire connections.

Installation location:
On transmissions with hydraulic regulation -E17-, the Sensor for
Transmission RPM is secured to the underside of the valve body (see
illustration). For these transmissions the sensor is an inductive sensor. Fig. 11 Sensor for Transmission RPM -G182-

On transmissions with hydraulic regulation -E182-, the transmission input
speed sensor -A- is secured behind the valve body at the transmission
housing. On these transmissions the sensor is a hall effect sensor.
