2022-2024 Audi e-tron GT Hood Release Procedure

Symptoms

Owners of 2022-2024 Audi e-tron GT and RS e-tron GT models may experience a situation where the hood cannot be opened if the 12-volt battery has been depleted. This condition prevents access to the engine compartment for charging or service. When the 12-volt battery is dead, the electronic hood release mechanism will not function, necessitating a manual Audi e-tron GT hood release procedure.

Important Warnings

Audi has issued specific warnings regarding this procedure:

• Vehicle Movement: "Since the wheels will be blocked by the parking pawl or the parking brake, wheel dollies will be needed to maneuver the vehicle onto a hoist." This indicates that the vehicle may not be easily moved without specialized equipment, even if the hood is released.
• Warranty Coverage: "This TSB is informational only and not applicable to any Audi warranty." This means that any costs associated with performing this manual hood release procedure are not covered under Audi's standard warranty.

Technical Background

This Technical Service Bulletin (TSB) 00 23 65 2064296/2, issued on April 13, 2023, addresses the manual hood release for the Audi e-tron GT and RS e-tron GT. It supersedes an earlier bulletin, Group 00 number 21-50, dated August 17, 2021, primarily to include additional model years. The document clarifies that the emergency power supply procedure detailed in the Self-Study Program (SSP) 684 for the Audi e-tron GT (type F8) is not applicable to the US market. Therefore, a specific manual procedure is required when the 12-volt battery is depleted.

Repair Procedure Summary

To perform the manual Audi e-tron GT hood release, technicians must follow a specific sequence of steps:

1. Access Underbody: The vehicle must be raised, and the underbody panel removed to gain access to the hood latch mechanism. This initial step requires a vehicle lift and appropriate tools for panel removal.
2. Locate Actuator: From underneath the vehicle, the front hood latch release actuator, identified as F573, needs to be located. This actuator is connected to the hood latch via a Bowden cable.
3. Engage Bowden Cable: Using a long hook tool or a similar instrument, only the end of the Bowden cable should be slid towards the F573 actuator. This action manually disengages the hood latch.
4. Post-Release Actions: Once the hood latch is released, the vehicle's 12-volt battery can be accessed for charging. Following the battery charge, normal diagnosis of any related issues can proceed.

Required Tools

To safely and effectively perform the manual Audi e-tron GT hood release procedure, specific tools are necessary:

• Vehicle Lift: To raise the vehicle and provide access to the underbody.
• Wheel Dollies: Essential for maneuvering the vehicle onto a hoist, especially if the parking brake is engaged due to a depleted battery.
• Long Hook Tool: Required to manipulate the Bowden cable connected to the F573 hood latch release actuator.

Owner Action

If you own a 2022-2024 Audi e-tron GT or RS e-tron GT and find that your hood cannot be opened due to a depleted 12-volt battery, it is recommended to contact an authorized Audi service center. The manual Audi e-tron GT hood release procedure requires specialized equipment, such as a vehicle lift and wheel dollies, and should be performed by trained technicians. Be aware that, according to TSB 00 23 65 2064296/2, this procedure is informational and not covered under warranty.
