Owners of certain Audi Q7, Q8, SQ7, SQ8, and RS Q8 models may notice a distinct clicking noise when adjusting their steering column vertically. This issue, detailed in Audi Technical Service Bulletin (TSB) 2064535/2, addresses this specific concern to ensure a smooth and quiet operation of the steering column.

This TSB, identified as 48 22 25 2064535/2, supersedes a previous bulletin, Group 48 number 21-11, dated September 16, 2021. The updated bulletin provides revised information for addressing the steering column noise.

Symptoms

Owners report hearing "noises when adjusting the steering column vertically (clicking noise)". This clicking sound occurs specifically when the steering column is moved up or down.

Diagnosis and Trigger Conditions

Workshop technicians can typically reproduce the noise by vertically adjusting the steering column. The sound is localized to the pin/hinge area of the steering column assembly. Audi's technical background indicates that the steering column was initially assembled under tension, which is the root cause of the Audi Q8 steering column clicking noise.

Repair Procedure Summary

The repair outlined in TSB 2064535/2 involves replacing specific bolts within the steering column assembly. Technicians are instructed to refer to the Audi Repair Manual, specifically the "Chassis >> 48 Steering >> Steering Column" section in Elsa, for detailed instructions. The process requires careful adherence to the tightening sequence and torque specifications to ensure the issue is resolved correctly.

Important Warnings for Technicians and Owners

Audi emphasizes several critical points for the repair:

• "It is crucial to follow the tightening sequence and torque specification exactly." Incorrect tightening can lead to further issues or prevent the resolution of the clicking noise.
• "Use new bolts only." Reusing old bolts is not permitted and may compromise the repair's effectiveness.
