50 Creaking noises heard when body twists during braking or steering maneuvers 50 20 03 2061672/1 December 16, 2020. Model(s) Year VIN Range Vehicle-Specific Equipment A6, A7 2019 - 2021 All Not Applicable A6 allroad, S6, S7, and RS7 2020 - 2021 All Not Applicable RS6 Avant 2021 All Not Applicable Condition Customer states: A creaking type noise is heard in the floor area. The noise can be generated during strong braking or steering maneuvers where the vehicle body is twisted. Workshop findings: Diagnosis locates the source of the noise from the floor area specifically radiating from the footwell to the area under the seat. Technical Background During a cornering or hard braking maneuver the longitudinal members can make contact with their internal support plates. Production Solution There has been an improvement in the construction of the longitudinal member assembly. Service 1. Duplicate the noise on a test drive preferably with the customer so that the conditions under which this symptom presents are clearly identified. If this noise is duplicated on the test drive confirmation that the source of the noise is from the longitudinal member and that the repair described in this TSB will be effective can be achieved as follows.

Begin your diagnosis by loosening the front most bolt on the subframe mounting as indicated in Figure 1. The bolt only needs to be loosened several turns but not removed. Figure 1. Front most bolt on subframe to be loosened. Note: As specified in the repair manual, it is necessary to replace all loosened subframe bolts at the conclusion of the entire repair. 3. In many cases an audible ‘cracking’ noise can be heard in the course of loosening and tightening the subframe bolt (Figure 2). Figure 2. Loosening the front most subframe bolt. 4. Test drive the vehicle. If no change or elimination of the noise is achieved during this diagnostic step, the repair in this TSB will not be effective and diagnosis must continue outside the scope of this repair procedure. If the noise characteristics do, in fact, change or if the noise is eliminated proceed as follows. Page 2 of 12 © 2020 Audi of America, Inc. All rights reserved.

Duplication of this noise is difficult when the vehicle is cold. If you suspect that the cold is preventing duplication of this symptom warm up the longitudinal member/body in the area of the rear transverse link bolted connection with a hot air blower set for an outlet temp of approximately 550°C (1022 °F) (Figure 3). Figure 3. Warming the area of the body near the rear transverse link. 6. Warm the surface to approximately 65 °C (149°F) (Figure 4). Figure 4. Surface temperature warmed to 65° C (149°F).

Allow the surface temperature to cool to approximately 30 °C (86°F) then test drive the vehicle again. Figure 5. Surface temperature cooled to approximately 30° C (86°F). 8. Merely lowering the vehicle from the hoist can immediately elicit the noise symptom after this warming process. 9. With the symptom confirmed, lower the center cover plate on the affected side. Remove the first body plug aft of the bolted connection for the transverse link (Figure 6). Note: Replace the body plug removed in this step with 8K0 805 267. Figure 6. Body plug removed.

In order to provide appropriate access to the affected area inside the longitudinal member remove sections of the acoustic foam in the longitudinal member area with long needle nosed pliers. It is not necessary to remove all of the acoustic foam and the small amount removed for this procedure will not need to be replaced (Figure 7). Figure 7. Remove a portion of the acoustic foam. 11. An improvised tool for this modification will be fabricated. Obtain a steel rod 60 cm long (Figure 8). Figure 8. Tool to be fabricated. Page 5 of 12 © 2020 Audi of America, Inc. All rights reserved.

Grind the tip of one end of the rod into a chisel shape. The length of the grind should be 15mm +/-3mm on each side as shown in Figure 9. Figure 9. Ground tip of steel rod. 13. Insert the chisel end of the steel rod into the body opening, through the remaining acoustic foam and far enough to engage the longitudinal member support (Figure 10). Figure 10. Insert of the steel rod. Page 6 of 12 © 2020 Audi of America, Inc. All rights reserved.

Using a hammer drive the steel rod a distance of 4 – 5 cm. Ensure the correct distance measure and mark this distance on the steel rod with tape (Figure 17). Figure 17. Driving the steel rod into the longitudinal member support. 21. Perform a final test drive to confirm elimination of the noise by duplicating the driving conditions specified by the customer. Ensure that the noise has been eliminated to the customer’s satisfaction by driving with the customer at the time they take possession of the vehicle after repair.
