2021-2023 Audi e-tron Rear Camera Washer Malfunction TSB

Symptoms

Owners of 2021-2023 Audi e-tron and e-tron Sportback vehicles may notice that when they activate the washer system for the rearview camera, the lens remains dirty. This is typically due to the water pressure being too low to effectively clean the camera.

Diagnosis / Trigger Conditions

If your Audi e-tron camera washer is not performing as expected, a technician will first rule out other common causes of low pressure. These include:

• Low washer fluid solvent levels.
• A clogged filter on the pump.
• Low system voltage.
• Obvious kinks in visible washer lines.
• Plugged nozzles.

If these external factors are not the cause, the issue is likely the mono pump itself, which is unable to generate sufficient system pressure for proper cleaning.

Repair Procedure Summary

To resolve the insufficient pressure issue with the Audi e-tron camera washer, the repair involves replacing the existing mono pump with a dual pump version. The steps include:

1. Inspection: Verify that no other issues (like low fluid or clogged lines) are causing the low pressure.
2. Pump Replacement: Remove the existing mono pump and install the new dual pump.
3. Hose Connection: Install the filler plug onto the black outlet of the new pump. The hose should then be attached to the white outlet.
4. Non-Return Valve: A non-return valve must be fitted to the white outlet to prevent any pressure drop in the system.
5. Electrical Correction: The polarity of the pump connector needs to be reversed. This means swapping the positive and negative pins within the connector that connects to the pump.
