2021-2023 Audi e-tron Rear View Camera Washer Pressure Low TSB

Symptoms

Owners of certain 2021-2023 Audi e-tron and e-tron Sportback vehicles may notice that when they activate the washer system for the rearview camera, the pressure is insufficient to clean the lens of the camera. This results in a blurry or obstructed view from the rearview camera, impacting visibility and safety during maneuvers.

Diagnosis and Technical Background

Upon inspection, technicians have found that the system pressure of the mono pump, which is responsible for delivering washer fluid to the rearview camera jet, is not high enough. The technical background confirms that the mono pump itself is unable to produce the necessary system pressure required for effective cleaning. This inherent design limitation of the mono pump is the root cause of the Audi e-tron camera washer issue.

Production Solution

To address the problem of low washer jet pressure, Audi implemented a change in the production process. The original mono pump design has been superseded by a more robust dual pump design. This dual pump system is engineered to provide adequate pressure for the rearview camera washer, ensuring proper cleaning and clear visibility.

Important Warnings and Pre-Checks

Before proceeding with any repairs for a low Audi e-tron camera washer pressure issue, it is crucial to rule out other common causes. Technicians must first ensure there are no other reasons for low system pressure, such as low washer solvent levels, a clogged filter on the pump, low system voltage, or obvious kinks in the visible washer lines. Only if these external factors are not present should the pump replacement be considered.

Additionally, when performing the repair, it is critical to use only the specific parts listed in this Technical Service Bulletin 2073568/1. These parts include superseding numbers to ensure compatibility and correct functionality, preventing further issues or improper repairs.

Repair Procedure Summary

If the low pressure is confirmed to be due to the mono pump and not other external factors, the repair involves replacing the existing mono pump with the updated dual pump version. During this process, a specific plug must be installed on the black outlet of the new dual pump. This procedure ensures that the new dual pump operates correctly and delivers the necessary pressure to the rearview camera washer jet, resolving the Audi e-tron camera washer problem.
