Technical Background These noises can be caused by an improperly seated rear bump stop (which occurs when the rear bump stop was not fully inserted into the rear shock absorber mounting during PDI). A bump stop installation tool (SET900) was developed to aid with the installation of rear bump stops during PDI (Figure 1). This tool provides the necessary leverage to seat the rear bump stop in the shock absorber mounting. Figure 1. The SET900 bump stop installation tool. © 2023 Audi of America, Inc.

Technical Service Bulletin One SET900 tool was sent to all Audi dealers in November 2014. Additional tools can be purchased through the Audi Special Tools and Equipment Program Production Solution Not applicable. Service To ensure proper installation of rear bump stops (in Audi models without air suspension): 1. Clean the top of the rear bump stops and coat with tire mounting paste. 2. Use the SET900 special tool to fully press the rear bump stops into the upper shock mounts (Figure 2). 3. The purpose of the tool is to properly seat the rear bump stops in the rear shock mounts (Figure 3), which will prevent them from dropping out of the rear upper shock mounts and causing the noise.
