This TSB, identified as 40 23 63 2047758/11, supersedes previous bulletin 40 23 59 dated June 6, 2023. The latest revision, dated June 29, 2023, includes updated model year information and revised parts and tools details.

Symptoms of Front Shock Absorber Noise

Owners typically report hearing "Cracking noises/spring jumps when steering or when maneuvering." This Audi front shock absorber noise can often be reproduced when at least two people are in the vehicle and the steering wheel is turned just before reaching the right or left stop. These sounds indicate an interaction issue within the front suspension system.

Technical Background

The root cause of the Audi front shock absorber noise is identified as the buffer stop for the shock absorber making contact with the front shock absorber cap. This friction between these two components during steering or maneuvering creates the audible cracking or jumping noises reported by customers.

Repair Procedure Summary

To address the Audi front shock absorber noise, technicians are instructed to lightly lubricate the contact surface between the buffer stop and the front shock absorber cap. This involves applying 5 grams of grease, specifically part number G 000 405 A2, to each side of the vehicle. During this process, it is also recommended to check the protective sleeve of the front shock absorber to ensure it is correctly fitted and can turn easily in the axial deep-groove ball bearing or sleeve bearing.

Required Parts

The primary part required for this repair is a specific type of grease:

• G 000 405 A2: Grease (Quantity: 1)

Additionally, any necessary fasteners, bolts, nuts, and screws should be referenced and procured via ETKA/ELSA according to the repair manual.
