Important Warnings for Owners and Technicians

Audi has provided several critical warnings and instructions related to Service Action 93P9 that both owners and technicians should be aware of:

• Inventory Vehicles: Dealers must ensure that every affected inventory vehicle has this campaign completed before delivery to consumers.
• Free Service Expiration: This service action is available free of charge only until September 01, 2027. If a customer wishes to have this service performed after this date, normal dealership costs will apply.

• Flashing Method: "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 update must be performed using the "Flash" operating mode, not "Diagnosis" (Guided Fault Finding), to ensure claim payment.
• Safety Recalls: All safety recalls must be completed prior to performing this campaign.
• Battery Charger Connection: When connecting the battery charger, connect the positive cable to the positive terminal and the negative cable to the grounding lug on the chassis. "DO NOT connect the ground cable directly to negative terminal of the battery."
• Hazard Lights: "The procedure may cancel itself if the hazard warning lights are not switched on. The hazard warning lights prevent the system from switching to bus sleep mode during the update."
• Damages and Pre-existing Conditions: Damages resulting from improper repair or failure to follow work instructions are the dealer's responsibility and not eligible for reimbursement. Diagnosis and repair of pre-existing conditions in the vehicle are not covered under this action.
• ODIS Sessions: All campaign software updates must be completed during a single, standalone ODIS Diagnostic Session. Technicians must fully complete this campaign and send all logs before beginning any other campaigns or operations.
• ODIS Hot-Fix Patches: If there are any ODIS "Hot-Fix" patches installed, they must be removed from the scan tool before beginning this operation, as they may affect the update process.

Required Tools or Parts

To perform the 2022 Audi e-tron GT software update, technicians will need specific equipment:

• Battery Tester/Charger: Capable of a minimum 90 Amp continuous supply, specifically the -VAS5908- battery charger.
• Diagnostic Tester: -VAS6150X/VAS6160X- or an equivalent diagnostic system.

Detailed Repair Procedure

Service Action 93P9 involves a precise software update process. Here's a summary of the steps an authorized Audi dealer will follow:

1. Pre-Repair Checks and Preparation

Before starting the software update, technicians must:

• Verify Eligibility: Enter the vehicle's VIN into the Elsa system and check the "Campaign/Action" screen. The campaign status must show "open." If other open actions exist, the customer should be informed so all work can be completed concurrently.
• ODIS Software Update: Ensure the ODIS software on the VAS Diagnostic Tester is completely up to date by checking the "Alerts" section on the ServiceNet homepage for the current ODIS version.
• Diagnostic Tester Settings: Turn off the screen saver and power saving settings on the diagnostic tester to prevent it from entering power save mode during the update, which could damage the control module.
• Diagnostic Tester Power: Ensure the VAS Diagnostic Tester is plugged in using the supplied power adapters. It should not be used on battery power alone during the software update to prevent powering off and potential control module damage.

2. Vehicle and Equipment Setup

Proper setup is critical for a successful update:

• Battery Charger Connection: Connect the -VAS5908- battery charger to the vehicle's 12V battery. The charger must be capable of a minimum 90 Amp continuous supply and maintain battery voltage above 12.5 volts throughout the update. When connecting, attach the positive cable to the battery's positive terminal and the negative cable to the grounding lug on the chassis. Do NOT connect the ground cable directly to the negative terminal of the battery.
• Charger Configuration: Switch the -VAS5908- battery charger off and then on again, ensuring its display switches off before restarting. Set it to a charging voltage of 14.8 Volt and operate it in charging mode.
• Ignition and Consumers: Switch the vehicle's ignition on. Switch off all electrical consumers, such as headlights, heated seats, and climate control.
• Diagnostic Tester Connection: Connect the -VAS6150X/VAS6160X- Diagnostic Tester to the vehicle. The VAS Diagnostics Interface must only be connected to the tester with a USB cable; Bluetooth or WiFi connections are prohibited to prevent connection loss and potential control module damage.
• Hazard Lights: Turn the vehicle's hazard warning lights on. This prevents the system from switching to bus sleep mode during the update, as the procedure may cancel itself if the hazard lights are not switched on.

3. Diagnostic Scan and Bus Sleep (Pre-Update)

• Initial Diagnostic Scan: Perform a full diagnostic scan using the "Diagnosis" operating mode within the ODIS program. Send the diagnostic protocol online and save the diagnostic session for later use.
• Initiate Bus Sleep: Disconnect the 12V charger and remove the diagnostic interface from the vehicle. Close all doors, the hood, and the rear lid. Lock the vehicle and wait 1 to 2 minutes for it to enter bus sleep mode.

4. Software Update Execution (Service Number 93P9)

• Reconnect and Start Flash: Reconnect the diagnostic interface via USB. From the scan tool's home screen, highlight and select the "Flash" operating mode. It is crucial to use the "Flash" operating mode, not "Diagnosis" (Guided Fault Finding), as using GFF will prolong the process and may lead to non-payment of the claim. Follow the on-screen prompts.
• Select Options: Select "Starting Flashing" and follow the on-screen prompts. Then, select "No RO." Highlight "SVM – Code Input."
• Enter SVM Code: Select "Perform test" and enter the corrective action code 93P9A388 when prompted. Accept the code and continue to follow the on-screen instructions.
• Labor Operations: The labor operations associated with this service action include connecting the battery charger (Labor Op 2706 89 50, 10 Time Units), GFF Operations (Labor Op 0150 00 00, Time stated on diagnostic protocol), and performing the software update via Flash (Labor Op 9301 25 99, Time stated on diagnostic protocol). The Service Number for claiming is 93P9, with Damage Code 0099 and Parts Vendor Code 002.

5. Post-Update Procedures and Final Checks

• Ignition Cycle: After receiving confirmation that the flash completed successfully, turn the vehicle's ignition off for 60 seconds, then turn it back on. This extra ignition cycle step is necessary to clear any faults stored during the update.
• Exit Flash Session: Click "Flash" to exit the flash session.
• Bus Sleep (Post-Update): To clear any generated fault codes, disconnect the diagnostic tester, remove the key from the vehicle, and lock the vehicle with the remote for 5 minutes to induce bus sleep mode.
• Instrument Cluster Check: Check the instrument cluster for any fault messages or warning lamps; none should be present.
• Parking Brake Position Detection: If necessary, perform position detection for the parking brake by pressing the brake pedal, moving the selector lever to "N" for 5 seconds, waiting another 5 seconds, and then applying the parking brake. If the brake warning lamp still flashes, recalibrate and extend the waiting time.
• Charging Profile Restoration: For vehicles equipped with a 22 kW onboard charger, the charging profiles must be restored to factory settings. This is done using the "Diagnosis" operating mode, selecting "Self test," then "00C6 - High Voltage Battery Charger Control Module -J1050-" and "C6 - Reset charging timer and charging profiles to factory settings." Exit Diagnosis and send the diagnostic protocol online.

6. Documentation

• Diagnostic Protocol: After the update and all checks are complete, send the final diagnostic protocol online.
• Campaign Stamp: Once the campaign is completed, the technician will stamp the repair order using item# AUD4927ENG (for English-speaking regions) or AUD4927FRE (for French-speaking regions).
