Service

It is not necessary to receive an authorization number from the Technicians Helpline for the repair described in this bulletin.

Note:
Any Update Programming procedure (flash) may overwrite any "TUNED" ECM or TCM programming. A "TUNED" ECM or TCM is described as any ECM or TCM altered so as to perform outside the normal parameters and specifications approved by Audi of America, Inc.

Current Tuned ECM or TCM requirements: If you encounter a vehicle with a "Tuned" ECM or TCM, your dealership must do the following before performing any procedure that updates ECM or TCM programming:

^ Notify the owner that their ECM or TCM was found to have been tuned

^ Notify the owner any damage caused by the tuning of the ECM or TCM (including any adverse emissions consequences) will not be covered by Audi of America, Inc. warranties.





^ Obtain the owner's written consent (Refer to Control Module Tuning form shown) for any requested repair under warranty or outside warranty that requires flashing, which will automatically overwrite the "Tuned" program.

Flash the TCM with the update CD - Part Number: 8N0-906-961.

Before flash update, delete the fault memory in the transmission control module. Flash update isn't possible when an EEPROM fault is active.

After inserting the Flash CD in the VAS 5051 and accessing the transmission control unit the programming starts by pressing the Update button.

If the update button doesn't appear, the latest version has already been installed.
