Technical Background
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 that 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 (see attached Control Module Tuning form) for any requested repair - under warranty or outside warranty - that requires flashing that will automatically overwrite the tuned program.
Production Solution
New software in the Engine Control Module resolved the problem.
Service
It is not necessary to create a TACS ticket or to receive an authorization number from the Technical Assistance Center for the repair described in this bulletin.
Update the ECM using the SVM action code as listed in the table.
- If the vehicle has a tuned ECM or TCM, ensure the Control Module Tuning form has been filled out by the owner.
Tip:
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.
- For further SVM update instructions and troubleshooting, please refer to the SVM Operating Manual; ElsaWeb TSB 2011732.
