Volkswagen Tiguan Service and Repair Manual: Rear Parallel Parking Assist Sensors

Rear Parallel Parking Assist Sensors, Removing and Installing

The rear parallel parking assist sensors are installed in the rear bumper cover. Both of the rear parallel parking assist sensors sit on the bumper cover outermost positions on the sides and are used with the parking aid sensors for measuring during the parking process.

The following rear parallel parking assistance sensors are located in the rear bumper cover:

  • Right Rear Parallel Parking Assistance Sensor -G717-
  • Left Rear Parallel Parking Assistance Sensor -G716-

Removing

  • Switch off the ignition and all electrical consumers and remove the ignition key.

Caution

Always follow the sequence for removing the sensor.

Otherwise, the sensor may be damaged. Hairline cracks which lead to sensor failure can develop if too much force is used on the sensor.

First remove the sensor from the bracket and then disconnect the connector from the sensor.

  • Remove the rear bumper cover.
  • Push the retainers -arrows- on the sensor bracket -1- toward the outside and pull the sensor -2- out of the bracket with the wires still connected.

Note

  • When removing the sensor, make sure that the decoupling ring (black silicone ring) remains on the sensor head and does not remain in the bracket or get lost.
  • Do not bend the decoupling ring.

  • Disconnect the connector -2- and remove the sensor -1-.

Installing

Install in reverse order of removal. Note the following:

Caution

A damaged coupling ring can cause malfunctions.

Do not bend the decoupling ring.

Replace damaged decoupling rings.

Note

Since the lengths of the sensor heads of the parking aid and the parallel parking assistance sensors are different, the high coupling rings installed are also different.

  • Make sure the correct decoupling ring is installed on the sensor head.

Type of Sensor Height of Decoupling Ring -B-
Parking Aid Sensor 5.7 mm
Parallel Parking Assistance Sensor 9.05 mm

Note

  • When installing the sensor, make sure the decoupling ring is correctly mounted on the sensor head and that it does not fall off or roll up when being inserted into the sensor bracket.
  • Both locking mechanisms on the sensor mount must audibly engage when installing the sensor.

  • Make sure the sensor is seated correctly in the bracket after installation. Dimension -a- for the circular gap between the sensor head and bumper cover must be visibly even all around on the outer side of the bumper cover.

Parallel Parking Assistance Sensor, Replacing

The rear parallel parking assist sensors are installed in the rear bumper cover. Both of the rear parallel parking assist sensors sit on the bumper cover outermost positions on the sides and are used with the parking aid sensors for measuring during the parking process.

If a new parallel parking assistance sensor is installed, the sensor head must first be painted to match the color of the bumper cover. The following requirements must be observed when painting the sensors to ensure that the parallel parking assistance will work correctly.

Sensor, Painting:
  • Remove the decoupling ring (black silicone ring) from the new sensor head.
  • Use isopropyl alcohol to remove the grease from the black sensor head -1- in the area to be painted -2-.
  • Paint the sensor in the area to be painted -2- the same color as the bumper cover.

Note

Paint application dimension -B- is 3 mm (+ maximum 2 mm).

  • When the paint has dried, reinstall the decoupling ring (black silicone ring) on the sensor head.

Caution

  • Do not bend the decoupling ring.
  • Using a damaged decoupling ring can cause malfunctions.
  • Replace damaged decoupling rings.

Rear Parallel Parking Assist Sensors, Checking

The rear parallel parking assist sensors are installed in the rear bumper cover. Both of the rear parallel parking assist sensors sit on the bumper cover outermost positions on the sides and are used with the parking aid sensors for measuring during the parking process.

Checking the rear parallel parking assist sensor is identical to checking the front parking aid sensor or front parallel parking assist sensor.
