2021-2023 Audi e-tron Rear View Camera Washer System TSB

Symptoms of Insufficient Camera Washer Pressure

Owners of 2021-2023 Audi e-tron and e-tron Sportback vehicles may notice that when they attempt to use the washer system for the rearview camera, the pressure is insufficient to effectively clean the camera lens. This can lead to a blurry or obscured view, impacting visibility and safety.

Technical Background

Audi Technical Service Bulletin 92 25 44 2073568/4 identifies the root cause of the insufficient cleaning pressure. The original mono pump installed from the factory may not generate enough system pressure and lacks a non-return valve. This design limitation prevents the washer fluid from reaching the camera lens with adequate force to clear debris.

Important Warnings for Technicians

Before proceeding with any repairs, technicians must verify that the mono pump with part number 1K5 955 651 is the factory-installed component. Audi's Electronic Parts Catalog (ETKA) can be used to confirm the original part. This TSB is only applicable if this specific mono pump is present. Additionally, it is crucial to rule out other common causes of low system pressure, such as low washer fluid, a clogged pump filter, low system voltage, kinks in visible lines, or plugged nozzles.

Repair Procedure Summary

If the 2021-2023 Audi e-tron is experiencing the Audi e-tron rear view camera washer issue due to the mono pump, the repair involves replacing the existing mono pump with a dual pump version. The general procedure outlined in TSB 2073568/4 includes:

1. Diagnosis: First, the technician will reproduce the customer's complaint to confirm the issue is related to insufficient washer pressure for the rear view camera.
2. Pre-checks: Other potential causes for low pressure, such as low washer fluid or clogged nozzles, must be thoroughly checked and ruled out.
3. Pump Replacement: The mono pump will be removed and replaced with a new dual pump.
4. Component Installation: A filler plug is installed on the black outlet of the new dual pump.
5. Hose Connection: The washer hose is attached to the white outlet of the dual pump.
6. Non-Return Valve: A non-return valve is fitted to the white outlet to prevent pressure drop in the system.
7. Wiring Modification: The pump connector polarity must be reversed by swapping the positive and negative pins in the connector to the pump.
