2007-2026 Audi Noise and Vibration Diagnosis TSB

Symptoms

Owners of 2007-2026 Audi vehicles may experience "noise or vibration complaints." These concerns can often be duplicated by technicians, but the underlying cause is not immediately apparent, making diagnosis challenging. This is where the specialized diagnostic procedure comes into play for the 2022 Audi e-tron noise vibration issue.

Diagnosis with PICO-NVH Tool

This Technical Service Bulletin (TSB) outlines the process for professional noise and vibration analysis using the VAS 611 015 PICO-NVH tool. This tool, along with acceleration sensors and microphones, helps precisely detect the sources of unwanted noises and vibrations. Essential information like engine speed and vehicle speed is recorded via the OBD adapter VAS 6154 for subsequent analysis.

For Audi e-tron vehicles specifically, technicians must ensure the newest PICO software version is installed to correctly record vehicle speed signals. Additionally, the "EV” setting must be selected within the PICO software when connecting the VAS 6154 on-board diagnosis adapter.

Repair Procedure Summary

The diagnostic process involves several key steps to accurately identify the source of the 2022 Audi e-tron noise vibration:

1. Setting-up Time: Technicians will spend approximately 50 Time Units (TU) setting up the VAS 611 015 PICO-NVH tool for noise analysis (repair operation 01610000).
2. Measurement/Test Drive: A measurement drive is conducted to gather data. The time required for this step (repair operation xxxx0199) is billed based on the component being investigated.
3. Analysis/Evaluation: After the test drive, the collected measurements are analyzed. This step (repair operation xxxx0199) is also billed based on the time needed for analysis.
4. Repositioning Measuring Technology: If further analysis is required, sensors may need to be repositioned, which takes approximately 25 TU (repair operation 01613199).

Detailed guidelines for acoustic analysis, measuring points on the transmission, and connecting the VAS 6154 to the PICO NVH tool are attached to the TSB for technicians.

Required Tools and Software

To perform this diagnostic procedure, technicians need specific equipment:

• VAS 611 015 VAS PicoScope NVH Kit: This is the minimum required tool for the analysis.
• VAS 6154: This OBD adapter requires a specific driver to be installed on the workshop laptop.

Software updates for the VAS 611 015 PICO-NVH tool and instructions for connecting the VAS 6154 can be found on Audi ServiceNet under Workshop Equipment >> Tool Information >> Tool Software Updates. These updates are crucial for obtaining live road speed signals and engine RPM data.

Important Documentation

All work performed during the diagnosis of the 2022 Audi e-tron noise vibration must be thoroughly documented. This includes:

• Attaching photos of sensor positions, with at least one photo showing the vehicle identification number (VIN).
• Labeling photos clearly (e.g., "sensor A measurement setup 01").
• Making a note of the mileage before and after any test drive.
• Keeping screenshots of the measurement report from the analysis.
• Documenting the reason for any repositioning of sensors and providing photos of new sensor positions.

Warranty Information

This diagnostic procedure is covered under warranty for up to 48 months or 50,000 miles, whichever comes first. If the vehicle is outside of this warranty period, the Technical Service Bulletin serves as informational guidance only. All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual and are subject to review by Audi Warranty.
