APB5 - Replacing the Cell Block Module on High-Voltage Battery (Recall Campaign)

Vehicle Type:

Taycan (Y1A / Y1B / Y1C)

Model Year:

As of 2020 up to 2024

Concerns:

Cell block module

Cause:

There is a possibility that, under certain circumstances, a defect in the battery cells installed in
the high-voltage battery can occur on the affected vehicles.
In this case, a short circuit within the battery modules during the vehicle’s service life cannot be ruled out,
which could lead to thermal events and later to a fire in the vehicle.

Action:

Replace cell block module.
Information
To find out the campaign scope for Replacing the cell block module assigned to each vehicle, see
PCSS Vehicle Information.
Depending on the cell module that was affected, the vehicle was precisely assigned to a scope.
Scope 1-33 is only valid for vehicles with a high-voltage battery with 33 modules
Scope 34-59 is only valid for vehicles with a high-voltage battery with 28 modules

NOTES about Warranty Processing for Multiple
Campaigns:
Please see the Warranty processing section at the end of
the TI for more detailed notes. Vehicles assigned to APB5
are also assigned to WRJ5 Workshop Campaign. The
Scopes table on this page denotes the affected battery
module that is being replaced. Both campaigns must
be closed at the same time. There are different items to
invoice on each Campaign Warranty claim. Please see
the table in the Warranty Processing section for a detailed
breakdown of which campaign to claim each item under.

Information
Processing of multiple campaigns
Processing APB2 recall campaign
If, in addition to this campaign, the APB2 campaign has
not yet been carried out on a vehicle, the leak test of the
high-voltage battery must first be carried out as part
of the APB2 campaign.
•

If the test result is positive (high-voltage battery is
leak-tight), APB5 campaign can be carried out.

•

If the test result is negative (high-voltage battery
Allocation of scopes to cell block module
is leaking), implementation of APB5 campaign is
no longer necessary due to the necessary replacement of the high-voltage battery and can be
concluded. After carrying out campaign APB2, campaign APB5 is to be closed by performing a
recall update (warranty claim with 0 material units and 0 time units).

Processing campaign APB5
As previously communicated via PPN, Porsche's partner, EVBS is doing the module replacement. Your
Porsche Center will still be billed for and reimbursed via Warranty claim for all of the necessary parts
used, but the new parts will come already installed in the battery by EVBS.

Replacing cell block module
Work
Procedure:

Prep Work - Reach out to EVBS at [email protected] to acquire a DDR crate that will be
used to ship the affected battery to EVBS.
1

Create Vehicle Analysis Log (VAL) using the PIWIS Tester. Mark the vehicle analysis log you have just
created with the attribute “Pre-VAL”.

2

Remove the battery and prepare for shipment to EVBS. These instructions are contained within
"Preliminary Work" section, steps 1 to 4 of  Workshop Manual '2X00IN General warning notices for
working on the high-voltage on-board system'

3

Leak test the HV Battery After removal as part of preparation for shipment to EVBS. NOTE: Please
leak test the battery after removal and before shipping to EVBS. These instructions are contained
within "Preliminary Work" section, steps 1 to 4 of  Workshop Manual '2X00IN General warning
notices for working on the high-voltage on-board system'
If you have already performed the leak test as part of APB2 during the same workshop visit and the
battery passed the leak test, you may skip this step.
If the HV Battery fails the leak test per the Workshop Manual, replace the battery and DO NOT send
the battery to EVBS. If you require a new HV Battery, please submit a PRMS Parts Support ticket to
Bill Trusky for release of the battery. Please mention APB5 in ticket.

4

Once the requested crates has arrived at the Porsche Center, take photos of the DDR
crate before and after crating the affected battery. Packing instructions can be found here:
https://ppn.porsche.com/portal/docs/DOC-514996
After the affected battery has been packaged, contact EVBS at [email protected]
to arrange for a logistics pickup. **Please ensure the entire battery is shipped, do not remove the
ebox or other related components**. The only parts you can safely remove prior to crating the
battery are:

5

Following the battery & crate being picked up, expect to receive a follow up email from EVBS to
arrange for a logistics drop off of the repaired battery & crate.

6

Once your PC receives the battery from EVBS, take photos of the crate and battery upon inspection.
If there are any incidents, report them to EVBS.

Information
PLEASE NOTE THAT IT IS PERMISSIBLE TO MOVE THE VEHICLE AFTER THE BATTERY HAS BEEN
REMOVED. Normally this would not be approved, but because of the repair taking place outside the
Porsche Center, the vehicle can be moved off of the lift after the battery is removed. THE BATTERY
COVER MUST BE REINSTALLED BEFORE MOVING THE VEHICLE. THE SPEED LIMIT WHILE MOVING THE
VEHICLE WITH NO HV BATTERY INSTALLED IS 4 MPH. There are further instructions at the end of this
document.
7

Install the HV Battery with the new cell module(s) and then store the new Serial Number(s) of the
cell module(s) in PCSS. EVBS will deliver the battery and crate with details of the removed and new
battery module(s) serial numbers. These will be needed for the warranty process. For instructions,
see  Workshop Manual '270855 Replacing cell block module'
NOTE: Your PC will only be responsible for entering the new Serial Number(s) of the replaced cell
modules and the re-installation of the HV Battery. The steps for entering the new Serial Number(s)
are contained in the "Reworking" Section, steps 8 and 9 of WM270855 and the re-installation
instructions for the HV Battery are contained in "Reworking" Section, steps 14 through 27 of WM
270855.

8

Create Vehicle Analysis Log (VAL) using the PIWIS Tester. Return the vehicle analysis log you have
just created with the attribute “Post-VAL” using the PIWIS Tester.

9

Alert EVBS to arrange a crate pickup for the crate and materials used to transport the battery.
Logistics will be handled by EVBS.

10 Enter the campaign in the Warranty and Maintenance logbook.

Warranty processing
Information
The specified working times were determined specifically for the completion of this campaign and may
differ from the working times published in the Labor Operation List in PCSS.
Repair depth:

The Porsche Center is only responsible for removing the battery, performing the leak test
before shipment, and then shipping the battery to EVBS. Then, installing the HV Battery when it
returns from EVBS. Your Porsche Center will receive information with the battery from EVBS on
the new Serial Numbers for the replaced battery modules, which you will need to enter in PCSS
in order to properly document the repair.

be added manually, and labor will pay out 1085 TU.
WRJ5 Scope 2: Claim Scope 2 when the HV Battery fails the leak test during shipment prep and must
be fully replaced. All parts will need to be added manually, and labor will pay out 1085 TU. NOTE:
DO NOT send an HV Battery to EVBS if it has failed the leak test during prep.

NOTE: If more than one HV Battery module is replaced by EVBS, that means that they found more than the
required modules were potentially faultly. PCNA has authorized EVBS to replace any modules found to
be potentially faulty. If more than one module is replaced, it must be invoiced on the WRJ5 Campaign. HV
Batteries and Cell modules cannot be invoiced as subsequent credit appeals, as it will not trigger a
serial number change in PCSS.

Information
•

No damage on the body due to movement / transport is to be expected if the high-voltage
battery is removed / not installed

•

Wheel alignment is not necessary if chassis connection points are not loosened

•

The rolling speed of max. 4 mph should not be exceeded

Procedure to “release” the parking brake with removed high-voltage battery using the PIWIS
tester
1. Establish readiness for operation (switch on ignition)
2. Release the parking brake in the PCM menu
3. Set transmission control unit in N position via selector lever
4. Set transmission control unit in N position via selector lever
5. Using the PIWIS Tester in the motor electronics (DME) control unit
 Coding programming
 Customer-specific settings
 Block parking lock
 Change status from “not active” to “active” and write with [F8]
Note:
This coding on “active” sets a fault in the motor electronics control unit (DME) and a red warning message
is triggered in the instrument cluster
After the repair, the following must therefore be carried out:
1. the coding must be reset to “not active”
2. the fault memory must be deleted
