2017-2023 Audi Q5, Q7, Q8 Front Suspension Noise TSB

Owners of certain 2017-2023 Audi Q5, Q7, Q8, SQ5, SQ7, SQ8, and RS Q8 models may experience rumbling or knocking noises emanating from the front suspension. This issue, specifically the Audi Q8 front suspension noise, is addressed by Audi Technical Service Bulletin (TSB) 40 22 36 2059996/2, released on March 16, 2022. This bulletin supersedes an earlier TSB, Group 40 number 20-11, dated July 8, 2020, which was initially published on July 2, 2020. The current revision (Revision 2) updated the header to include additional model years.

Symptoms of Front Suspension Noise

Vehicle owners may notice "rumbling or knocking noises" coming from the front end of their vehicle, particularly when driving on uneven roads. Workshops have confirmed that this noise can be consistently reproduced during diagnosis.

Technical Background

Audi has identified that the root cause of this rumbling or knocking noise is often "tension in the body." This tension can develop around the bolted connection of the front tower brace, leading to audible symptoms.

Repair Procedure Summary

To resolve the Audi Q8 front suspension noise and similar issues in other affected models, Audi outlines a straightforward service procedure:

1. Check Tower Brace Connection: A technician will first inspect the bolted connection of the front tower brace.
2. Secure Bolts: If necessary, the technician will secure the bolts to the correct torque specifications. This step is crucial for relieving the tension in the body that causes the noise. The procedure requires consulting the repair manual for precise torque values, specifically within Elsa at "Repair Manual, Chassis >> Suspension, Wheels, Steering >> 40 Front Suspension >> Suspension Strut, Upper Control Arm >> Overview Tower Brace."

Figures 1 and 2 in the TSB illustrate the tower brace location. Figure 1 provides an example for an Audi Q7, showing the brace in the engine bay. Figure 2 offers a detailed technical diagram of the tower brace for an Audi Q5, highlighting the bolted connections that need to be checked and torqued. After securing the bolts, the technician will reassess the vehicle to ensure the concern is resolved.
