About this Service
Action
The charging equipment provided with the Audi vehicles in this service action can be used to
its full capacity by following the safety information provided in the Owner’s Manual and by
ensuring that a qualified electrician has inspected the home’s electrical wiring for safe operation
of the charging equipment. Should the proper electrical requirements not be met, use of the
compact charging system with improper or overburdened 220V power outlets and wiring may,
in certain circumstances, lead to a risk of overheating of the home infrastructure. Power outlets
and wiring incapable of handling the required electrical current can cause electric shock or
home infrastructure damage when charging the high-voltage battery using the compact
charging system.
Corrective Action
Audi has decided to have an authorized Audi dealer change the setting on the charging system
control unit to 50% and attach a warning label to the control unit of the Audi compact charging
system.
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.
NOTE: The charging equipment provided by Audi has been tested and can be used to its full capacity
if the safety information provided in the Owner’s Manual is observed and by ensuring that a qualified
electrician has inspected your home’s electrical wiring for safe operation of the charging equipment.
It will still be possible to charge at a charging current of 100% by pressing the button (100%) on the
control unit. If a customer does this, they should be sure that their home power supply meets all the
requirements for safely charging the high-voltage battery at a current rating of 40 amperes, which
likely requires additional amperage capacity to meet applicable electrical codes (please confirm with

Subject: Service Action 93K8 - Portable Charging Unit Default Setting & Label
Dear Audi Owner,
As part of Audi’s ongoing commitment to customer satisfaction, we are informing you of our decision to conduct a service action on certain
2019-2021 model year Audi vehicles. Our records show that you are the owner of a vehicle affected by this action.
About this Service Action:
The charging equipment provided with your Audi vehicle can be used to its full capacity by following the
safety information provided in the Owner’s Manual and by ensuring that a qualified electrician has
inspected your home’s electrical wiring for safe operation of the charging equipment. Should the proper
electrical requirements not be met, use of the compact charging system with improper or overburdened
220V power outlets and wiring may, in certain circumstances, lead to a risk of overheating of the home
infrastructure. Power outlets and wiring incapable of handling the required electrical current can cause
electric shock or home infrastructure damage when charging the high-voltage battery using the compact
charging system.
What will we do?
Audi has decided to have an authorized Audi dealer change the setting on the charging system control
unit to 50% and attach a warning label to the control unit of your Audi compact charging system. We
would therefore ask you to bring the charging equipment that came with your 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.
This work will take about an hour to complete and will be performed for you free of charge.
NOTE: The charging equipment provided by Audi has been tested and can be used to its full capacity if
the safety information provided in the Owner’s Manual is observed and by ensuring that a qualified
electrician has inspected your home’s electrical wiring for safe operation of the charging equipment. It

battery” chapter of your Audi vehicle’s Owner’s Manual. If you have any questions or concerns about the
adequacy of your home power supply, please consult with a qualified electrician to ensure it meets these
requirements.
What should you do?
In order to limit any possible inconvenience, please contact your authorized Audi dealer as soon as
possible to schedule this service. Please keep in mind that your dealer may need additional time for the
