2022 Audi Q7, Q8, SQ7, SQ8 Underbody Water Leak TSB 51H9

The Issue: Underbody Water Leak

Audi has identified a manufacturing issue affecting certain 2022 Audi Q7, Q8, RS Q8, SQ7, and SQ8 models. Specifically, a paint drain hole located on the front left of the vehicle's underbody was not properly sealed. This oversight stems from a change in component specifications during production. As a direct consequence, water can enter the vehicle's interior through this unsealed paint drain hole, potentially leading to dampness or water accumulation inside the cabin.

This condition, identified in Audi Dealer Communication Update 51H9, means that owners of affected vehicles may experience a 2022 Audi Q8 underbody water leak or similar symptoms in other models. The communication highlights the importance of addressing this issue to prevent further water intrusion and potential damage to the vehicle's interior components.

Repair Procedure Summary

Audi Technical Service Bulletin 51H9 outlines a specific repair process to address the underbody water leak. The primary step involves properly sealing the affected paint drain hole on the underbody of the vehicle. Following this, technicians are instructed to perform a thorough check to determine if any water has already entered the vehicle's interior or underbody due to the unsealed opening.

Detailed repair instructions are available to dealerships through Audi's ELSA/ServiceNet system. For dealership inventory, a daily campaign open inventory report or OMD (Open Market Data) report should be checked to identify affected vehicles. All identified vehicles in dealer inventory must undergo this repair before they can be delivered to consumers. There is no special parts allocation for this repair; parts will be managed via Free Order, and the Repair Projection Tool can be used to view potential VIN populations.

Important Warnings for Owners

Next Steps for Owners
