About this Service
Action
Campaign status must show “open.”
If ELSA shows other open action(s), inform your customer so that the work can also be completed at
the same time the vehicle is in the workshop for this campaign.
On certain vehicles built during a limited production period, oversensitive diagnostic software
could cause the message, “Error: selector lever. You can drive on. Please visit workshop” to be
displayed in error. To address this condition, Volkswagen
is providing a software update for the
gearbox control unit. This software will enhance the function of the mechanical “emergency
park lock” system with an electric “emergency park lock” system so that unwarranted error
messages do not occur.
As a reminder, your vehicle owner’s manual contains important information regarding your
vehicle’s warning lights and messages. We encourage you and anyone who drives your vehicle
to review the owner’s manual to become familiar with the types of vehicle indicators, warnings
and messaging you may see.

Section B – Update Transmission Control Module
NOTE
Prior to launching the VAS Diagnostic Tester and starting an update, ensure the following conditions are
met;
The ODIS software is completely up to date.
•
Refer to the “Alerts” section on ServiceNet home page for the current ODIS version.
The battery charger is connected to the vehicle battery and remains connected for the duration of
the software update.
•
Battery voltage must remain above 12.5 volts (or higher, if directed in the work instructions) for
the duration of the software update. Failure to do so may cause the update to fail, which could result
in damage to the control module. Control modules damaged by insufficient voltage will not be
covered.
The screen saver and power saving settings are off.
•
Failure to do so may result in the tester entering power save mode during the software update,
which could result in damage to the control module.
The VAS Diagnostic Tester is plugged in using the supplied power adapters.
•
Under no circumstances should the tester be used on battery power alone during the software
update. Failure to do so may result in the tester powering off during the update, which could
result in damage to the control module.
The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable.
•
Performing a software update using a Bluetooth or WiFi connection increases the risk of losing
connection during the update, which could result in damage to the control module.
It also greatly increases the time required to perform the update. Requests for additional time
or parts will be denied if the GFF log shows the update was performed using Bluetooth or WiFi.
NOTE
•
Damages resulting from improper repair or failure to follow these work instructions are the dealer’s
responsibility and are not eligible for reimbursement under this action.
•
Diagnosis and repair of pre-existing conditions in the vehicle are not covered under this action.
NOTE
•
All campaign software updates must be completed during a single, standalone ODIS Diagnostic Session.
You must fully complete this campaign and send all logs before beginning any other campaigns or
operations.
•
If there are any ODIS “Hot-Fix” patches installed, they must be removed from the scan tool before beginning
this operation. ODIS “Hot-Fix” patches may affect the update process.
The repair information in this document is intended for use only by skilled technicians who have the proper tools, equipment and training to correctly and safely maintain your vehicle. These
procedures are not intended to be attempted by “do-it-yourselfers,” and you should not assume this document applies to your vehicle, or that your vehicle has the condition described. To
determine whether this information applies, contact an authorized Volkswagen dealer. 2025 Volkswagen Group of America, Inc. and Volkswagen Canada. All Rights Reserved.

IMPORTANT
To Update-Programming using SVM, review and follow instructions in Technical Bulletin 2014603: Software
Version Management (SVM) Operating Instructions.
The SVM Process must be completed in its entirety so the database receives the update confirmation response. A
warranty claim may not be reimbursed if there is no confirmation response to support the claim.
•
Switch off all consumers, air conditioning, heater blower motor, lights, heated seats, etc.
•
Connect battery charger.
•
Ensure the latest version of ODIS is downloaded.
•
Ensure diagnostic head is connected to ODIS tester via USB cable.
•
Move selector lever to P.
•
Use operating mode, DIAGNOSIS.

Select “SVM – Code Input”.
•
Enter SVM code FDQP and follow the on screen prompts.
•
Ensure the diagnostic log is sent to GFF Paperless after completion.
Proceed to Section C
IMPORTANT
If the software update fails for any reason, ODIS feedback must be sent prior to further diagnosis. This ensures the
failure/error is reported. Failure to do so may result in non-payment of consequential requests for additional time or
parts.

Section C – 12V Battery Drain Evaluation
NOTE
After the software update is completed, it is possible that a 12V battery draw is introduced. The root cause of this is
still under investigation.
The following steps provide direction on how to quickly check if the draw is introduced and how to eliminate it.
•
After the flash is complete, remove the
diagnostic head from the vehicle, disconnect
the battery charger, roll down the driver’s
window and lock the vehicle.
•
Wait 5 minutes.
•
Observe the gearshift illumination.
•
If the E816 Parking Lock Button and Y5
Selector lever Transmission Range Display
lights are still illuminated, the 12V battery
draw is present.
•
If the lights are not illuminated, the 12V battery
draw should not be present.
•
To correct the draw, remove fuse SC42 for a
few seconds and then reinstall it.
o
•
Reference “Component Locations:
Fuses” in the Repair Manual/Wiring
Diagram
After the car is locked, the draw should be
eliminated and the E816 Parking Lock Button
and Y5 Selector lever Transmission Range
Display lights should not be illuminated.
