2022-2026 Audi Frequency Analysis App TSB 2051095/10

Audi Technical Service Bulletin (TSB) 2051095/10, released on February 20, 2026, is an informational document detailing the availability and usage of the Audi Frequency Analysis app. This bulletin is not issued in response to a specific customer complaint or vehicle defect. Instead, it serves as a guide for Audi technicians on how to utilize this specialized diagnostic tool to more accurately pinpoint the source of various noise complaints across a wide range of Audi vehicles.

The Audi Frequency Analysis app is designed to assist workshops in assessing and diagnosing vehicle noise issues. By analyzing the frequency of reported noises, technicians can gain a more precise understanding of the complaint, which can then lead to more targeted and effective repair measures outlined in other specific TSBs.

App Availability and Versions

The Audi Frequency Analysis app is available for download on both Apple and Android platforms. Technicians can access the app through the respective app stores:

• Apple App Store: https://apps.apple.com/us/app/audi-frequency-analysis/id1589055470
• Google Play Store: https://play.google.com/store/apps/details?id=de.audi.frequenzanalyseapp&gl=DE

It's important to note that the Android and Apple versions of the app may currently differ in their functionality, programming, and availability. Audi is actively developing a new Android version intended to align the characteristics and operation of the app across both operating systems, ensuring a consistent user experience for all technicians.

How the Audi Frequency Analysis App Works

Upon opening the basic application, technicians can record a noise complaint directly. This recording can then be played back and paused for detailed analysis. By interacting with the diagram displayed within the app, technicians can determine the precise frequency at which the noise complaint occurred. The app also allows for adjustments to the diagram's view through an options menu, though this is often not necessary for basic diagnosis.

All recorded noise files can be accessed via the "Files" section within the app. Once a file is selected, it can be further analyzed, edited, sent to other external applications for transmission (if needed), or deleted. This comprehensive functionality helps streamline the diagnostic process for various noise-related concerns in 2022-2026 Audi vehicles.

Important Warnings for Owners

Owners should be aware that Audi Technical Service Bulletin 2051095/10 is purely informational. It outlines the use of a diagnostic tool for technicians and does not refer to a specific complaint or vehicle issue that would typically warrant a repair under warranty. Therefore, this TSB is not applicable to any Audi Warranty and does not describe a repair procedure covered by warranty.

Technical Background

The core purpose of the Audi Frequency Analysis app is to precisely identify the frequency characteristics of a noise complaint. Understanding the specific frequency of a noise helps technicians narrow down potential causes, as different vehicle components often produce noise at distinct frequency ranges. This technical approach allows for a more scientific and efficient diagnosis compared to subjective listening alone.

Service Use

Technicians are instructed to use the Audi Frequency Analysis app to diagnose noise complaints with greater precision. This enhanced diagnostic capability allows them to identify targeted measures for specific complaints, which may then be addressed through existing technical service bulletins or repair procedures. The app acts as a valuable front-line tool to gather objective data about noise issues, guiding the technician towards the correct repair strategy.
