2021-2023 Audi e-tron Washer Fluid Reservoir Leak TSB

Symptoms

Owners of affected 2021-2023 Audi e-tron and e-tron Sportback vehicles may observe a "Washer fluid reservoir leaking" condition. This symptom indicates a loss of windshield washer fluid, which can reduce visibility during driving if the reservoir empties.

Diagnosis and Trigger Conditions

Audi Technical Service Bulletin 2075757/1 identifies the root cause of the Audi e-tron fluid leak as a "Filler connection not fitted correctly." This means the hose that supplies washer fluid to the reservoir was not properly seated or secured during vehicle assembly. Technicians can visually inspect the filler hose connection to confirm it is not fitted correctly, as illustrated in the TSB's Figure 1.

Repair Procedure Summary

The repair for the Audi e-tron fluid leak involves correctly seating the washer fluid filler connection and inspecting a key seal. The procedure, as outlined in TSB 2075757/1, includes the following steps:

1. Remove Filler Connection: The first step requires removing the filler connection for the washer fluid, following specific repair instructions. This process is depicted in Figure 2 of the TSB.
2. Detach Filler Neck: The filler neck must then be carefully pulled out of the washer fluid reservoir. Figure 3 in the TSB provides a visual guide for this step.
3. Inspect and Replace Seal: Technicians must check the seal, identified by part number 8T0955465A, for any damage. If the seal is compromised, it must be replaced to ensure a proper, leak-free connection.
4. Reassembly: The assembly is performed in the reverse sequence. It is crucial to ensure that the seal is not squeezed or pinched during the reinstallation of the filler connection to prevent future leaks.
