2021-2023 Audi A4 / A5 / S4 / S5 / RS 5 Steering Squeak TSB 2055733/3

Symptoms of an Audi Steering Squeak

Owners of certain 2021-2023 Audi models may notice a distinct "squeaking noise from the steering column" when turning the steering wheel slowly. This Audi steering squeak may become more pronounced or louder under specific conditions, such as higher ambient temperatures or after extended driving periods. The noise typically originates from the sealing sleeve or the steering column opening on the bulkhead.

Technical Background

Audi Technical Service Bulletin 2055733/3 identifies the root cause of this Audi steering squeak as the incorrect positioning of the sealing sleeve (also known as the sealing lip) within the bulkhead. This issue is often compounded by unfavorable tolerances of the surrounding components. Technicians have observed that the steering shaft might rest on the cone of the sealing sleeve, especially when the steering column adjustment is set in the lower range.

Repair Procedure Summary

To resolve the squeaking noise, Audi has outlined a specific repair procedure in TSB 2055733/3. This involves repositioning the intermediate steering shaft and its associated sealing sleeve. The general steps are as follows:

1. Disconnect the intermediate steering shaft: The intermediate steering shaft must first be disconnected from the steering column.
2. Adjust the rubber sealing sleeve: The rubber sealing sleeve (labeled 'A' in technical diagrams) needs to be loosened. It is then pushed upwards as far as possible to ensure correct positioning and subsequently retightened.
3. Reinstall the intermediate steering shaft: The steering intermediate shaft (labeled 'B') is reinstalled and connected to the steering column (labeled 'C'). New bolts (labeled 'D') are used to secure the connection, ensuring proper torque and alignment.

For comprehensive repair instructions, technicians are directed to the Elsa Repair Manual, specifically the section on "Chassis >> 48 Steering >> Steering Column >> Steering Intermediate Shaft, Removing and Installing."

Important Warnings

Audi emphasizes a critical safety warning regarding this repair: "There is a risk of accident due to an absence of traction if the steering intermediate shaft is installed incorrectly. Pay attention to the installation position and installation instructions." This highlights the importance of having this repair performed by a qualified technician who can follow the precise installation guidelines.

Required Parts and Tools

During this repair, certain parts are mandatory replacements. Technicians must refer to the component overview and parts catalog (such as ETKA/ELSA) to identify and order the necessary fasteners, bolts, nuts, and screws. These components ensure the integrity and safety of the steering system after the repositioning of the intermediate steering shaft.
