Owners of certain Audi e-tron and e-tron Sportback models may encounter an issue where the rearview camera washer system fails to adequately clean the camera lens. Audi has released Technical Service Bulletin (TSB) 2073568/2, also known as 92 24 42, to provide guidance for diagnosing and resolving this problem. This TSB, revised on December 9, 2024, supersedes previous bulletin 92 24-38 dated April 5, 2024.

This bulletin specifically addresses the condition where "Cleaning rear view camera system not possible" due to insufficient water pressure. The primary cause identified is a mono pump that cannot generate enough system pressure for effective cleaning.

Symptoms

If you own a 2021-2023 Audi e-tron or e-tron Sportback, you might notice that when you activate the rearview camera washer, the pressure is "insufficient to clean the lens of the camera." This means the water stream is too weak to clear dirt or debris from the camera, impairing visibility.

Diagnosis and Trigger Conditions

According to Audi's workshop findings, the core issue is that the system pressure of the mono pump is not high enough. Before proceeding with a repair, technicians are instructed to rule out other common causes of low washer system pressure. These include low washer solvent levels, a clogged filter on the pump, low system voltage, obvious kinks in visible lines, or nozzles that are not plugged.

If these other potential issues are not present, the problem is confirmed to be with the mono pump's inability to produce sufficient pressure for the Audi e-tron rear camera washer system.

Repair Procedure Summary

The repair outlined in TSB 2073568/2 involves replacing the existing mono pump with a more robust dual pump version. The general steps for this repair are as follows:

1. Initial Inspection: Verify that there are no other reasons for low system pressure, such as low fluid, clogged filters, or pinched lines.
2. Pump Replacement: Remove the inadequate mono pump and install the specified dual pump.
3. Hose and Plug Installation: A filler plug (part number 3V0 955 235 A) must be installed on the black outlet of the new pump. The washer hose is then attached to the white outlet, which features a non-return valve to prevent pressure drop.
4. Wiring Adjustment: The polarity of the pump connector must be reversed by swapping the positive and negative pins in the connector.

This procedure ensures that the Audi e-tron rear camera washer system can deliver adequate pressure for effective cleaning.
