Technical Service Bulletin Service 1. Ensure the customer’ s phone is listed in the Audi Bluetooth approved list located on the www.audiusa.com/bluetooth website. Not all Bluetooth call quality issues can be attributed to the microphone. OEM phone manufacturers use different types of Bluetooth chipsets and software which have different characteristics (i.e. timing of timeouts) and as a result these differences can also affect the Bluetooth connection stability and call quality. For TT/A5 Cabriolet only: Road test the vehicle prior to repairs. Drive with the top and windows up and at a speed of 45mph or greater if possible. Make a Bluetooth call to someone back at the workshop to verify the call quality issue. Make sure the same person will be available for you to call back the next day once the repairs are completed to verify the call quality improvement. 2. Remove the roof module from the vehicle according to the instructions in the ElsaWeb Repair Manual. Repair Manual>>Electrical System>>Electrical Equipment>>96 Interior Lights, Switches>>Removal and Installation>>Roof Trim Lamps and Switches 3 Do Not Remove the microphone from the roof module at this step! The next step is to remove the decorative trim plate from the roof module. This will allow you to inspect the seal of the microphone as it was installed at the factory. a For the A6 and A7 vehicles, first attempt to use your fingers to pry the decorative trim from the base plate. If this does not work then gently use a trim stick/bone tool to pry the decorative trim from the base plate and finish it with your fingers. There are a different number of clips holding the trim plate on to the base plate depending on the trim level of the vehicle (i.e. high-line roof module vs. low-line roof module; see Figure 1 & 2).

Technical Service Bulletin b For the TT/A5 Cabriolet vehicles, the decorative trim plate should only be pried from the base plate after the LED circuit boards are removed from the plastic LED jewels. If this is not done prior to removing the trim, the plastic LED jewels can break and cause a rattle once the roof module is reassembled. As seen in Figure 3, first pry up on the top of the small circuit-board in direction indicated by arrow 1 (away from LED Jewel). It will Figure 3. Prying the LED circuit-board of the jewel. only need to be lifted about 1-2mm, then pull up on the circuit-board in the direction indicated by arrow 2. This will release the circuit-board from the clear LED jewel. Repeat for the other side. Figure 4 shows the three attachment points of the LED Circuit board to the LED jewel. Figure 4. LED jewel attachment points. Page 4 of 10 © 2012 Audi of America, Inc. All rights reserved.

Technical Service Bulletin c Once the LED jewels are free from the circuitboards, the decorative trim plate can now be pried apart from the base plate. This can be accomplished by using your fingers and slowly prying the two pieces apart. There are many clip points along the edge holding the two halves together, thus slowly sliding your finger all the way around the perimeter between the trim plate and base plate is the easiest and most effective way to separate the two parts without damaging them. 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 decorative trim. Damage to paint on the sides of the trim can be visible once the part is Figure 5. Prying the trim plate from the base plate. reinstalled in the headliner. 4. Inspect the seal of the microphone for damage. There are two normal splits in the rubber seal. This is normal as long as the two halves of the seal are touching each other. If they are loose and move freely then this indicates damage to the seal. Figure 6 illustrates an undamaged seal and Figures 7 and 8 illustrate damaged seals. Figure 6. Undamaged seal.

Technical Service Bulletin Figure 8. Damaged seal, example 2. Figure 7. Damaged seal, example 1. 5. If any seals are damaged, replace the microphone set. Install the replacement microphone with the decorative trim removed from the base plate. This will allow you to inspect the new microphone seal after it has been snapped in to place. Take care when doing so to prevent any damage to the new microphone’ s rubber seal. Installing it perpendicular to the base plate, and doing so slowly, will help prevent any damage to the seal. Figure 9 illustrates the proper installation technique and Figures 10 and 11 illustrate the improper installation of a microphone. Figure 12 shows the resultant damage of improper installation. Figure 9. Proper installation. Page 6 of 10 © 2012 Audi of America, Inc. All rights reserved.

Technical Service Bulletin 7. For TT/A5 Cabriolet only: Visually inspect the round felt material on the underside of the decorative trim (Figure 13). This felt material pushes against the microphone’ s rubber seal and forms a barrier. If the material is bunched up and off center it can potentially cause an issue with the call quality by allowing unwanted noise to reach the Figure 13. Felt on backside of decorative trim. microphone. Replace the decorative trim according to ETKA if damage is found with the felt material or if the felt is not centered perfectly. 8. For TT/A5 Cabriolet only: Before installing the new microphone, partially pull out the foam which is inserted inside the microphone (Figure 14). This will allow for a better seal against the felt material. Figure 14. Foam is partially pulled out of the microphone. 9. For TT/A5 Cabriolet only: Road test the vehicle with the top up at a speed greater than 45mph if possible. Call the same person back at the workshop so they can verify the improved sound quality. If you still feel the sound quality is poor please contact the Technician’ s Assistance Center helpline. Page 8 of 10 © 2012 Audi of America, Inc. All rights reserved.
