ARA5 - Checking High-Voltage Battery and Replacing Cell Block Module if Necessary (Stop
Delivery/Recall Campaign)
Model Line:

Taycan (Y1A / Y1B / Y1C)

Model Year:

As of 2020 up to 2024

Concerns:

High-voltage battery

Cause:

Under certain circumstances, there is a possibility that the supplier of the battery cell/battery
module may have had production issues with the Affected Vehicles. In this case, a short circuit
within the battery modules during the vehicle’s service life cannot be ruled out under certain
circumstances, which could lead to thermal events and later to a fire in the vehicle.
For this reason, additional tests are required. The Affected Vehicles may only be delivered to customers if
these tests were carried out successfully beforehand.
If these tests were not carried out successfully, the Affected Vehicles may not be delivered to customers.
If the results of the tests show an abnormality, the affected battery modules must be replaced before
delivery to customers. The Affected Vehicles may not be delivered to customers without prior module
replacement.

Action:
Information
An evaluation of the state of the module cell block of the Affected Vehicles is carried out by the PAG
internal analysis of the VALs.
Valid (complete) workshop and OTA VALs are taken into account for the evaluation.
For vehicles for which no OTA VALs are available until the action is carried out, 1 to 3 workshop VALs
must be created and transmitted to PAG depending on the vehicle population, taking into account defined
process steps.

Information
OTA Vehicle Analysis Log (OTA VAL)
Due to the constant transmission of OTA VALs, vehicles can be evaluated in advance. In this case, the
analysis results are documented in the Steering Tool list and assigned directly to the scope, meaning that
a workshop visit is no longer required to create a VAL.
After the OTA-VAL results are available, affected customers must be actively contacted and informed
about the test result. Either they are asked to schedule a workshop appointment to carry out the
WRE1/2/3 campaign or else no further actions are required due to the positive test.
The prerequisites for transmitting online data such as VALs are as follows:

Affected
Vehicles:

•

Active Porsche Connect package (if generally available in the market)

•

Online software update activated in My Porsche

•

Consent for product improvement activated in My Porsche

•

Data connection established successfully

•

Privacy mode deactivated

Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
Information
Please note that the vehicles will initially be published without any scope allocation when the campaign
is published. After the submitted VALs are checked, the vehicles will presumably be assigned to the
required scope after 2 working days, depending on the test result.

1

Please only submit the warranty claim for recall
campaign ARA5 in WWS for Scope 2/3 or
4/5if the accompanying action has been fully
completed beforehand. This will ensure that
the campaign is documented as Completed in the
systems, reporting and with the authorities.

Open the front cover and connect a suitable battery charger, e.g., 90 A battery charger, to the
jump-start terminals and switch it on.

Open the door and position the driver’s key with the
back facing forward upright between the holding
strips in the rear drinks holder (emergency start tray)
to ensure a permanent radio link between the vehicle
and remote control.

3

Establish readiness for operation (switch on ignition).

Information
An active Internet connection with the PIWIS Tester must
be ensured. To log in using the PIWIS Tester, the techEmergency start tray
nician is required.
The PIWIS Tester must not be charged using the cigarette lighter!

4

Connect the PIWIS Tester to the vehicle communication module (VCI) via the USB cable.
Then connect the communication module to the vehicle and switch on the PIWIS Tester.

5

Create a Vehicle Analysis Log (VAL). Mark the Vehicle Analysis Log you have just created with the
attribute “Extra VAL” and return it using the PIWIS Tester after completion.

6

Charge the high-voltage battery of the vehicle on the driver’s side to 100% SoC via the charging port
with alternating current (AC).
To reduce the charging time, it is recommended that charging be carried out at industrial electrical
outlets, at E-charging stations, or at the wall box. Only charge the high-voltage battery at domestic
electrical outlets, provided no other charging option is available.

7

Start the charging process and note the time that 100% “Charging goal met at” is displayed in
the center console control panel.
The end time of the charging process is decisive for the creation of the additional Vehicle Analysis
Logs.
Please ensure that the following intervals are observed. Failure to do so may result in delays or an
invalid evaluation.

8

After a charge state of 100% SoC has been reached, maintain an idling time of 6 hours and then
create a second Vehicle Analysis Log (VAL).
Mark the Vehicle Analysis Log you have just created with the attribute “Extra VAL” and return it using
the PIWIS Tester after completion.

9

After the second VAL, maintain a further idling time of 66 hours and then create a third Vehicle
Analysis Log (VAL).
Mark the Vehicle Analysis Log you have just created with the attribute “Extra VAL” and return it using
the PIWIS Tester after completion.

The data analysis yields a positive result: Vehicle can be delivered to customer. Continue to
Warranty Processing, Scope 1.
The data analysis yields a negative result: In rare cases, it may be necessary to replace the cell
block module. If this is the case, the VIN is transferred to one of the accompanying WRE1/2/3
campaigns.
VAL faulty/insufficient: In very rare cases, additional VALs may be required.
