WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Audi SQ5, 2024 Audi Q5 e, 2024 Audi Q5, 2023 Audi SQ5, and 2023 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.

Install in the reverse order of removal while noting the following:

WARNING:

Risk of injury due to involuntary deployment.

Pay attention to the safety precautions when working with pyrotechnic components. Refer to SAFETY PRECAUTIONS WHEN WORKING WITH PYROTECHNIC COMPONENTS .
Before handling pyrotechnic components (for example, connecting a connector), the person handling it must "discharge static electricity". For example, this can be done by briefly touching the door striker.

-- Engage the pedestrian protection crash sensor into the molded foam part.

WARNING:

Risk of malfunction.

Do not kink or stretch the pressure hose.

The pressure hose must be inserted without any tension.

-- Install the molded foam part with the pedestrian protection crash sensor. Refer to Front Bumper .

-- Attach the connector -1- to the crash sensor until it clicks into place -arrow-.

-- Push in the connector lock -2- to secure the connector.

NOTE:

Make sure the connectors are pushed in all the way and that they engage audibly.

Make sure the wires are not pinched.

WARNING:

Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of injuries due to unintentional deployments when the battery is connected.

The ignition must be on when connecting the battery.
Make sure that no one is inside the vehicle at the time when the battery is connected.

-- Connect the battery ground cable with the ignition switched on. Refer to BATTERY, DISCONNECTING AND CONNECTING .

WARNING:

Repairing pyrotechnic components (for example the airbag and seat belt tensioner) incorrectly increases the risk of injuries due to unintentional deployments when the ignition is switched on.

If the ignition is not switched on after the battery is reconnected - >>indicator lamps in the instrument cluster do not light up<< - the ignition (key/button) may only be switched on when the driver seat is positioned all the way back.

NOTE:

If the Airbag Indicator Lamp -K75- indicates a fault after assembling, check the DTC memory, erase it and check it again using the Vehicle Diagnostic Tester.
