Summary

An erroneous warning message may appear in the instrument cluster due to overly sensitive diagnostic software. The message is accompanied by a fault stored in the control unit for high-voltage batteryeBay logo charging, which also prevents charging at 100% with a 110V cable. A software update will be performed to address this issue.Updated claiming instructions Included Appendix A with updated B200000 fault clearing instructions


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.

Flash process through “Audi Flashing” not Guided Fault Finding (GFF).

DO NOT USE Guided Fault Finding (GFF) to perform this flash. Using GFF will cause the flash to
take longer. Requests for additional time will not be considered.

The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable.

Performing a software update using a Bluetooth or Wi-Fi 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

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.

WARNING
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a serious risk that personal injury
may result if contact is made with spinning fan blades. Keep hands and all objects away from Radiator Fan(s) during
Update Process!

IMPORTANT
To Update-Programming using SVM, review and follow instructions in Technical Bulletin 2011732: Software
Version Management (SVM) Operating Instructions for the US, or 2037026: Working with the Software Version
Management (SVM) for Canada.
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.
IMPORTANT
To prevent charging of the high-voltage batteryeBay logo during the software update, the high-voltage cable is to be removed
BEFORE entry of the SVM code on vehicles with high-voltage components. Charging the high-voltage batteryeBay logo during
a software update can damage the high-voltage components.

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, FLASH.
Communication path = DoIP

o

Select “SVM – Code Input”.

Enter SVM code 93SGA591 and follow the on-screen prompts.

Ensure the diagnostic log is sent to GFF Paperless after completion.

NOTE
This software update addresses “DTC B200000: Control module faulty
(symptom 1049088) active/static”, stored in diagnostic address 00C6.
If the fault is still present after the flash is completed, refer to the instructions
found in Appendix A.
The post-flash log showing the fault was still stored must be uploaded to GFF
paperless.
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.
