2021-2024 Audi Q7, Q8 Steering Squeak TSB 2070913/1

Owners of 2021-2024 Audi Q7, SQ7, Q8, SQ8, and RS Q8 models may notice an Audi Q8 steering squeak or similar noise emanating from the foot well area while turning the steering wheel. This issue is addressed by Audi Technical Service Bulletin (TSB) 2070913/1.

Symptoms

The primary symptom reported by owners is a distinct squeaking noise. This noise is typically heard from the foot well area of the vehicle when the steering wheel is turned. Dealership technicians can usually reproduce this noise during inspection.

Diagnosis and Trigger Conditions

The root cause of the Audi Q8 steering squeak is identified as a rubber ring on the intermediate steering shaft. This rubber ring rubs against the sealing boot, creating the audible squeaking noise. The TSB does not list any specific diagnostic trouble codes (DTCs) associated with this condition, as it is a mechanical noise issue rather than an electronic fault.

Important Warnings

When performing the repair, it is crucial to follow the instructions precisely. The TSB specifically warns: "Please do not slide the rubber ring on the shaft. The sealing boot may be moved on the shaft." This indicates that improper handling could lead to further issues with the sealing boot.

For vehicles outside the warranty period, this Technical Service Bulletin is for informational purposes only. Owners should verify their warranty coverage with an authorized Audi dealer.

Repair Procedure Summary

The repair outlined in TSB 2070913/1 involves a modification to the intermediate steering shaft. The general steps are as follows:

1. Remove the intermediate steering shaft: The shaft is first removed from the vehicle and placed on a workbench for easier access. Figure 1 in the TSB illustrates the intermediate steering shaft.
2. Modify the rubber ring: Using a knife, the rubber ring located on the sleeve side of the intermediate steering shaft is cut at a 45-degree angle. Figure 2 provides a visual guide for this step, showing the precise cut to be made.
