The driver’s voice sounds muffled, as if it is being heard from under water. Technical Background The microphone seal was damaged during installation into the roof module. Production Solution Improved microphone installation procedure and optimized the microphone seal, beginning with January 2012 vehicle production. Microphones with improved seals are at the 03S level or greater (Figure 1). Figure 1. Microphones with improved seals. © 2014 Audi of America, Inc. Page 1 of 9 All rights reserved.

Technical Service Bulletin Service Tip: This bulletin does not allow for replacement of the microphones unless there is physical damage found to the rubber seal on the end of the microphone. Because there has been no hardware optimization to the microphone, replacing a microphone that is not damaged will not improve the sound quality. Confirm that the sound quality issue is not due to the phone or phone service provider: 1. Ensure that the customer’s phone is an Audi-approved Bluetooth device by checking the list located at http://audi-intelligence.com/bluetooth/prod/ 2. Before making any repairs, road test the vehicle at a minimum speed of 45 mph with the top up (if applicable) and all windows closed. 3. During the road test, verify the call quality issue by making a Bluetooth call to someone at the workshop. Make sure that the same person will be available to answer another call after any repairs are made so that the call quality improvement can be verified. 4. If no call quality issues are confirmed during the road test, end all analysis. The issue is most likely due to the customer’s phone and/or service provider, which can be demonstrated to the customer by using a different paired phone with a different service provider. In addition, it is normal to have a small amount of road noise in the A5 Cabriolet or TT Roadster, as the location of the microphone at the top of the windshield allows for noise to be easily transmitted. None of the repairs below will eliminate this small amount of road noise. If call quality issues are confirmed, proceed with the repair procedure below. Remove the trim plate in order to inspect the microphone: 1. Remove the roof module from the vehicle according to ElsaWeb>>Repair Manual>> Electrical System>>Electrical Equipment>>96 Interior Lights, Switches>>Removal and Installation>>Roof Trim Lamps and Switches. 2. Remove the decorative trim plate from the roof module in order to inspect the seal of the microphone. The decorative trim plate should only be pried from the base plate after the LED circuit boards are removed from the LED jewels in order to prevent the LED jewels from breaking and causing a rattle after reassembly: • To remove the LED circuit boards, first pry the top of the small circuit board away from the LED jewel, in the direction indicated by arrow 1 (Figure 2). It will only need to be lifted 1-2mm. Then, pull up on the circuit board in the direction indicated by arrow 2 (Figure 2) to release the circuit board from the LED jewel. There are three different attachment points of the LED circuit board and LED jewel (Figure 3). • Repeat for the other side. • Once the LED jewels are free from the © 2014 Audi of America, Inc.

Technical Service Bulletin circuit boards, the decorative trim plate can be detached from the base plate. Use your fingers to pry the two pieces apart. • There are many clip points holding the two pieces together. Sliding your finger slowly around the perimeter is the most effective way to separate the two parts without damaging them (Figure 4). Note: The use of a bone tool or screw driver is not recommended for this roof module assembly because it can damage the soft touch paint on the edge of the trim, which can be visible once the part is reinstalled in the headliner.

Technical Service Bulletin Inspect and replace the microphone: 1. Visually inspect the round felt material on the underside of the decorative trim (Figure 5). The felt material pushes against the microphone’s rubber seal and forms a barrier. The decorative trim should be replaced (see ETKA) if the material is bunched up or not centered perfectly, as it can potentially affect the call quality. Figure 5. Felt on backside of decorative trim. 2. Inspect the seal of the microphone for damage: • There are two splits in the rubber seal. This is normal as long as the two halves of the seal are touching each other (Figure 6). • If the two halves of the seal are loose and move freely, the seal is damaged (Figure 7). Figure 6. Undamaged seal. Figure 7. Examples of damaged seals 3. If none of the seals are damaged, reinstall the microphones into the roof module: © 2014 Audi of America, Inc. Page 4 of 9 All rights reserved.

Technical Service Bulletin • Ensure that the microphones are firmly seated. A loud snap can be heard and felt when the microphone is fully seated. Reinstall the roof module and retest for the complaint before proceeding with diagnosis. If the complaint cannot be reproduced, no additional action is necessary. If any of the seals are damaged, install a replacement microphone: • Before installing the new microphone, partially pull out the foam that is inserted in the microphone to allow for a better seal against the felt material (Figures 8 and 9). • In order to prevent damage to the microphone seal, install the microphone while the decorative trim is removed from the base plate. Slowly install the microphone perpendicular to the base plate (Figure 10). Do not install the microphone at an angle, as this may pinch the seal (Figures 11 and 12). • Carefully inspect the new microphone seal after it has been snapped into place. Figure 8. After modification, the foam should be partially pulled out of the microphone. Figure 9. Foam is partially pulled out of the microphone. © 2014 Audi of America, Inc. Page 5 of 9 All rights reserved.

Technical Service Bulletin Complete the repair: 1. After the repair, road test the vehicle at a minimum speed of 45 mph with the top up (if applicable) and all windows closed. 2. During the road test, verify the call quality issue by making a Bluetooth call to the same person at the workshop that was called before the repair in order to verify call quality improvement. 3. If the call quality is still poor, call the Technical Assistance Center (TAC). 4. If the seals and microphones are installed properly, continue with diagnosis.
