Parking Aid Sensor, Front

Parking Aid Sensor, Front

Parking aid sensor in front bumper cover:

• Left front parking aid sensor (G255)

• Left Front Center Parking Aid Sensor (G254)

• Right Front Center Parking Aid Sensor (G253)

• Right Front Parking Aid Sensor (G252)

Sensor retainer, bonding in bumper cover, refer to=> [ Front Parking Aid Sensor Bonding Bracket In Bumper Cover ] Front Parking Aid Sensor Bonding Bracket In Bumper Cover.

• The following illustrations show how to remove and install the left front parking aid sensor (G255).

• Removing and installing the other parking aid sensors is identical.

• It is possible to remove both outer left front parking aid sensors (G255) and the right front parking aid sensor (G252) through the opening for the fog lamp. Depending on the vehicle equipment level, either remove the bumper cover or remove the fog lamp. Refer to => [ Fog Lamp, Jetta ] Fog Lamp, Jetta or => [ Fog Lamp, Jetta GLI ] Fog Lamp, Jetta GLI.

• If a new parking aid sensor is installed, the sensor head must first be painted to match the color of the bumper cover. Refer to => [ Parking Aid Sensor, Painting ] Parking Aid Sensor, Painting.


• Turn off the ignition and all electrical consumers.

• Remove the key.

Removing

- Remove the front bumper cover.


• 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.

• Remove the sensor from the bracket first and then disconnect the connector from the sensor.

- Push the locking mechanisms - arrows - on the sensor mount - 1 - toward the outside.






- Pull the sensor - 2 - backward out of the sensor bracket with the wires connected.

• 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 coupling ring.

- Disconnect the connector - 2 -.






- Remove sensor - 1 -.

Installing

Installation is performed in the reverse order of removal. Note the following:


• Do not bend the coupling ring.

• An incorrect or damaged coupling ring can lead to malfunctions.

• Replace any damaged decoupling rings and be sure install the correct decoupling ring.

• Since the lengths of the sensor heads of the front parking aid are different, the high coupling rings installed are also different.

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











- Replace the sensor decoupling ring - 1 -.

- Install the sensor in the correct location in the bumper cover.

Sensor brackets are designed in different shapes and must be matched to the respective component location in the bumper cover.

Be sure to align the electric connection on the sensor when installing it.

Parking aid sensors allocation inside the front bumper cover






1. LF - outer left

2. FLC - front left center

3. FRC - front right center

4. RF - outer right


Make sure that the sensors - 1 -, - 2 -, - 3 - and - 4 - are matched up with the connectors.

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.

Both retaining clips on the sensor holder must engage audibly when installing 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 even all around on the outer side of the bumper cover.
