2021-2023 Audi e-tron Rearview Camera Washer Difficulty

Symptoms

Owners of 2021-2023 Audi e-tron vehicles may notice that when the "clean rearview camera function" is activated, the washer fails to spray solvent. Another common symptom is that the function must be activated several times before the solvent is sprayed. This issue directly impacts the effectiveness of the rearview camera, especially in conditions requiring frequent cleaning.

Technical Background

The problem with the Audi e-tron camera washer stems from the absence of a check valve in the washer solvent circuit leading to the rearview camera washer jet. Without this valve, the delivery tube for the solvent loses its prime during driving or when the rear lid is opened. The rearview camera washer system is designed to cancel additional wash cycles after four activations to conserve solvent. However, these four activations are often insufficient to fill and pressurize the circuit, preventing the camera from being cleaned until the ignition key cycle (KL15 circuit) is reset.

Revision History

This Technical Service Bulletin (TSB 92 23 32 2059228/3) was issued on January 19, 2023. It supersedes Technical Service Bulletin Group 92 number 22-27, dated February 7, 2022. The revisions include updates to the header for Model Year 2023, the addition of the e-tron Sportback and Model Year 2022, and revised service procedures and parts quantities.

Repair Procedure Summary

The repair for the Audi e-tron camera washer involves modifying the rearview camera washer circuit by installing a check valve assembly. This procedure ensures the solvent circuit maintains prime, allowing for immediate and effective spraying.

For the e-tron quattro model, the 4N0 955 481 A valve end of the new assembly is fitted to the 'T' section of the manifold. The 5M0 955 875 coupling piece end connects to the removed washer line, integrating the new assembly in line with the original setup.

For the e-tron Sportback quattro model, the 4N0 955 481 A valve end is fitted to the male fitting inside the rear lid handle. The 5M0 955 875 coupling piece end then connects to the removed washer line, similar to the e-tron model. After installation, the rearview camera washer must be activated several times to purge air from the solvent circuit and ensure it is filled.
