2019-2021 Audi Portable Charging Unit Service Action 93K8

Audi has initiated Service Action 93K8 for certain 2019-2021 Audi e-tron, Audi Q5, Audi A7, and Audi A8 vehicles. This service action focuses on the portable charging unit provided with these vehicles, aiming to mitigate a potential safety risk related to home electrical infrastructure.

The primary concern is that if the compact charging system is used with improper or overburdened 220V power outlets and wiring, it could lead to overheating of the home's electrical system. Such conditions pose a risk of electric shock or damage to the home infrastructure when charging the high-voltage battery.

Why This Matters

The portable charging equipment, while designed for full capacity use, relies on the home's electrical wiring meeting specific safety requirements. If a qualified electrician has not inspected the home's electrical system, or if the wiring is not suitable for the required electrical current, using the charger at its full capacity could be hazardous. The consequences range from electric shock to significant damage to your home's electrical infrastructure, making this a critical safety measure.

What's Being Addressed

This service action specifically targets the Audi portable charging unit service action and similar units for other affected models. Audi dealers will modify the default setting of the charging system control unit to 50% capacity. Additionally, a new warning label will be affixed to the control unit of the Audi compact charging system.

This adjustment ensures that the charger operates at a lower, safer default level, reducing the strain on potentially inadequate home electrical systems. The warning label provides clear guidance to owners regarding the unit's operation.

Owner Action

Owners of affected 2019-2021 Audi e-tron, Q5, A7, and A8 vehicles are required to bring their complete portable charging equipment to an authorized Audi dealer for this Audi portable charging unit service action. This includes:

• The control unit itself.
• The vehicle cable with the vehicle charging connector.
• The power cable with the power plug for standard household sockets.
• The power cable with the plug for 220/240V industrial sockets.

Your Audi dealer will perform the necessary updates free of charge. It is essential to bring all components of the charging equipment to ensure the service action can be completed correctly. If your authorized Audi dealer fails or is unable to complete this work free of charge within a reasonable time, you should contact Audi Customer Experience at 1-800-253-2834 (USA) or 1-800-822-2834 (Canada).

To check your vehicle's eligibility for this or any other recall/service campaign, visit the Recall/Service Campaign Lookup tool on www.audiusa.com and enter your Vehicle Identification Number (VIN).

Important Warnings

Audi has provided several critical warnings and pieces of information for owners and dealers regarding this Audi portable charging unit service action:

• "Customers are asked to bring the charging equipment that came with the vehicle, including: (1) the control unit, (2) the vehicle cable with vehicle charging connector, (3) the power cable with power plug for household sockets, and (4) the power cable with plug for 220/240V industrial sockets, to an authorized Audi dealer to take these steps."
• "It will still be possible to charge at a charging current of 100% by pressing the button (100%) on the control unit.
