2021-2023 Audi Q5/SQ5 Sunroof Water Leak TSB

Symptoms

Owners of 2021-2023 Audi Q5 and SQ5 models equipped with a panoramic sliding sunroof may notice moisture inside their vehicle. Common complaints include "moisture in the vehicle," "soaked carpets," or other visible "water damage." This issue occurs when water, which is normally drained from the sunroof frame, finds its way into the vehicle's interior. If you observe any signs of an Audi Q5 sunroof water leak, it's important to address it promptly.

Diagnosis / Trigger Conditions

The root cause of the 2021-2023 Audi Q5 sunroof water leak is typically related to the water drain hoses connected to the panoramic sliding sunroof frame. These hoses are designed to channel water away from the vehicle. However, they can become compromised in two primary ways:

• Kinked Hoses: During the installation of the headliner, the drain hoses may become kinked. This restricts water flow, causing it to back up and eventually spill into the vehicle interior.
• Blocked Hoses: Over time, dirt and debris can accumulate within the drain hoses, leading to blockages. Similar to kinked hoses, blockages prevent proper drainage, resulting in water intrusion.

To diagnose the problem, a technician will need to lower the vehicle's molded headliner to visually inspect the water drain hoses for any kinks or significant dirt accumulation.

Repair Procedure Summary

Audi Technical Service Bulletin 2075969/1 outlines the steps for addressing the panoramic sunroof water leak. The repair process involves several key stages:

1. Headliner Removal: The first step requires carefully lowering the molded headliner to gain access to the water drain hoses.
2. Hose Inspection: Technicians will visually inspect all water drain hoses. They will specifically look for any kinks or improper routing that could impede water flow. Kinked hoses, as illustrated in the TSB's figures, must be replaced.
3. Dirt Check: If the hoses are routed correctly and show no signs of kinking, they must then be checked for dirt and debris. Significant dirt residues indicate a blockage.
4. Hose Cleaning: If large dirt residues are found, all four water drain hoses must be thoroughly cleaned using the specialized tool SET6620 (formerly VAS6620).
5. Reassembly: Once the hoses are either replaced or cleaned and confirmed to be properly routed, the assembly is performed in reverse sequence according to the Workshop Manual. This ensures all components are correctly reinstalled.

Required Tools or Parts

For cleaning blocked water drain hoses, technicians will utilize a specific tool:

• SET6620 (formerly VAS6620): This specialized tool is essential for effectively removing dirt residues from all four water drain hoses.
