Note:This Technical Bulletin is only valid for vehicles with engine designation "G" as the 5th digit of the VIN.
Example: WAU_G_XXXXXXXXXXX
Perform the "Update - Programming" (flashing) procedure of the Engine Control Unit (ECM) using SW - Level 050 as follows:
7. "Update - Programming" procedure prerequisites
Tip:
^ The "Update - Programming" process may overwrite any "TUNED" ECM programming.
^ A "TUNED" ECM is described as any ECM altered so as to perform outside the normal parameters and specifications approved by Audi of America, Inc..
If you encounter a vehicle with a "Tuned" ECM, prior to performing the "Update - Programming" procedure:
^ Your Dealership should place the vehicle owner on notice in writing, that their ECM was found to have been tuned, and that any damage caused by the tuning of the ECM (including any adverse emissions consequences) will not be covered by Audi of America, Inc. warranties.
^ For any repair requested by the owner under warranty or outside warranty that requires flashing which will automatically wipe out the "Tuning" program, your Dealership should advise the owner of the above and get Owner's written consent (Refer to the Control Module Tuning form shown) to the flashing procedure.
Tool requirements
^ VAS 5051 or 5052 Diagnostic tool (with Basis CD V.07.01 and the Brand CD V.07.42.00 or higher) with old diagnosis logs erased prior to start.
^ "Update Programming" CD
Part No: 8P0 906 961 H
Tip:
Additional copies of the "Update - Programming" CD Part No: 8P0 906 961 H may be ordered from the Audi Technical Literature Ordering Center.
Vehicle requirements
^ Battery MUST have minimum no-load charge of 12.5V. Failure to maintain voltage during update process can lead to ECM failure (you must use an approved battery charger to maintain battery voltage).
^ VAS 5051/VAS 5052: connected to vehicle with battery voltage requirements met.
^ Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.
^ Vehicle electrical consumers are OFF (i.e. radio, lights, A/C, etc.).
"Update Programming" procedure, checking software level
Tip:
The CD ROM should be in the VAS 5051 /5052 when the scan tool is started up or, inserted when the start screen is showing. Check the light on the CD drive. It must have stopped flashing before going to the "Select Vehicle System" screen or the CD ROM will not be recognized.
- Switch ignition ON.
- Switch VAS 5051 or VAS 5052 diagnostic tool ON (with Update Programming CD in CD drive).
- Select "Vehicle Self Diagnosis" mode.
- Select Vehicle system "01-Engine electronics".
- Ensure that "Update - Programming" appears at the bottom of the screen.
If "Update - Programming" does not appear:
- Contact the Audi Helpline for further instructions, Programming the ECM cannot be performed.
- Check software level at arrow.
- Print out the displayed screen.
- Attach a copy of print to vehicle Repair Order.
If ECM software level (arrow) is 0050 or higher:
- Contact the Audi Helpline for further instructions, "Update - Programming" is not required.
If ECM software level (arrow) is lower than 0050:
- Proceed to "PRIOR to performing "Update - Programming".
Tip:
^ When performing the Update - Programming procedure, ALL DTCs for all Systems are erased.
^ DTCs linked to Guided Fault Finding function tests will be lost. Therefore, always address stored DTCs for Customer concerns unrelated to the Update - Programming procedure first.
PRIOR to performing "Update - Programming":
- Select "Vehicle Self Diagnosis" mode.
- Select Diagnosis function "00 - Collection services".
- Select "Check DTC memory - complete system". which will interrogate all fault memories.
^ When DTC interrogation is complete "Function Complete" will be displayed.
- Select back arrow < on navigation bar to return to vehicle systems screen.
- Select vehicle system "01 - Engine electronics".
"Update - Programming" procedure, performing
- Select "Update - Programming" option at bottom of screen (arrow).
- After selecting "Update - Programming" function, new software level 0050 is indicated along with approximate timing for update.
- By selecting the > button, the programming procedure begins.
Tip:
Once "Update - Programming" function has been started, switching ignition OFF or disconnecting the diagnostic connector may damage the ECM.
- Similar screen appears:
The previous data in the ECM is erased and the new data is being transferred to the module from the flash CD.
Tip:
Please do not carry out any other work on the vehicle during "Update - Programming" (Process could be interrupted).
Tip:
- If, during the "Update - Programming", a fault message is displayed:
- Confirm that VAS 5051 or VAS 5052 diagnostic tool power supply is adequate and that ALL appliances with high electromagnetic radiation (i.e. mobile phones) are switched OFF.
- The "Update - Programming" process must then be started from the beginning using the "Repeat" button (arrow). DO NOT use the "Cancel" button.
Once "Update - Programming" is complete, the control module must be re-initialized.
- The tester requests you to switch the ignition OFF.
- Switch ignition OFF
- Wait 20 seconds and switch ignition ON.
- Similar screen appears:
- Select "Repeat" button -arrow- to continue "Update - Programming" process.
- Similar screen appears.
- Print out the displayed screen.
- Attach a copy of print to vehicle Repair Order.
- Select forward arrow > on navigation bar.
Fault memories, erasing after "Update - Programming" To erase ALL fault memories:
- Select forward arrow > on navigation bar.
Once fault memories have been erased:
- Similar screen appears.
^ Old software level may still appear at (arrow)
^ Function ended appears at bottom of screen.
Finish update of the ECM:
- Select backward arrow < on navigation bar.
^ Similar screen appears.
- Updated software level "0050" will appear at (arrow).
^ Update - Programming CD can now be removed from VAS 5051 or VAS 5052 Diagnostic tool.
- Print the ECM screen to verify ECM update software level.
- Attach print to vehicle Repair Order.
- Select "02 - Interrogate fault memory" (P1624/15032 will be stored in ECM fault memory)
- Erase fault memory
- Select "Go to" then select "Exit"
- Set readiness code.
^ Use VAS 5051 or VAS 5052 to set readiness code.
Tip:
^ If the "Update Programming" was interrupted and an error message appeared, or DTC 18089, P1681 is present in the ECM, the engine may not start. The "Update - Programming" procedure will need to be performed again. Please call the Audi Dealer Technician Helpline. The collection services step for DTC checking and clearing does not need to be repeated. Select "Update - Programming" on the Select Diagnosis Screen.
^ The system needs a minimum of 2-3 cold-starts to fully adapt to the fuel quality and to the vehicle.
