Customer Letter Example (CANADA)
This notice applies to your vehicle: ,
Subject:

Service Action 93F1 – High-Voltage Battery
Certain 2016 Model Year Audi A3 e-tron Vehicles

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 2016 model year Audi A3 e-tron vehicles. Our records show that you are the owner of a
vehicle affected by this action.
What is the issue?

It is possible that the high-voltage battery housing bonded seam was made in a nonoptimal position. If this condition is present, moisture can enter the high-voltage
battery housing. The driver may be alerted to this condition by the illumination of a
high-voltage system warning indicator on the instrument cluster display.

What will we do?

Your authorized Audi dealer will disassemble and inspect the high-voltage battery for
corrosion.


If no corrosion is found, your dealer will install a new high-voltage battery
housing, which may take up to two days to complete.



If corrosion is found, the high-voltage battery will be replaced. Your dealer
will order the new battery for your vehicle, and once it arrives at the
dealership the replacement may take up to two days to complete.

Both the inspection and replacement (if necessary) will be performed for you free of
charge.
Precautions You
Should Take

Ensure all vehicle drivers have read the vehicle owner’s manual so they are familiar
with how the high-voltage battery system and associated warning lights work.
Please be aware that other conditions (unrelated to the issue described in this circular)
may cause a high-voltage battery system-related warning light in the vehicle to
illuminate. Customers should be prepared to cover diagnosis and repair costs
associated with these other, unrelated conditions.

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 preparation of the repair, as well as to accommodate their
daily workshop schedule.
This service action will be available for you free of charge only until December 31,
2022. If you wish to have this service performed after that date, your dealer’s normal
parts and labor cost associated with this repair will apply.
