Technical Service Bulletin Tip: This bulletin is not applicable if this vehicle has a Repair Authorization on this topic. If an applicable Repair Authorization is not followed, the claim will not be paid. Technical Background The vibrations felt by the customer could be a result of the harmonic vibrations caused by the radial force variation (RFV) of the tires or an imbalance of the wheel and tire assembly. Tire RFV (Uniformity): To understand the effects of RFV, imagine the tire as a collection of springs between the rim and the tire tread. If the “springs” are not uniform stiffness, a varied force is exerted on the axle as the tire rotates and flexes (Figure 1). This creates a vibration in the vehicle. Figure 1. Vibration source from radial force variation (A). The table below explains common causes of wheel-related and tire-related vibrations in the vehicle. Refer to Elsa>>Wheel and Tire Guide >> Diagnosis and Testing for further diagnostic procedures and other possible causes of vibration. © 2014 Audi of America, Inc. Page 2 of 8 All rights reserved.

Technical Service Bulletin Vibration Description Possible Cause Vibration felt in the steering wheel while at constant speed Increased radial forces or imbalance on the front tires Vibration in the entire vehicle Increased or critical radial forces or imbalance on the rear tires and possible on the front tires. Tip: Tires with higher mileage and/or wear should be inspected to determine the best correction for the issue (repair or replacement). Tire life and condition should be determined prior to starting any diagnosis or repair for a vibration. Production Solution Not applicable. Service Note that for all warranty vibration repairs, the Tire Data Sheet and Hunter RFV printouts must be completed and retained for warranty claim payment. Tire Data Sheet and Hunter RFV printouts should be sent to [email protected]. Failure to do so will result in non-payment of the claim. 1. Complete all of the following sections of this bulletin: • Prepare Tires for RFV Measurement • Measure Radial Force Variation and imbalance • Reduce Radial Force Variation and imbalance • Reinstall Wheel and Tire Assemblies 2. Only if vibrations are still present after completing all four sections, open a TAC ticket and include the completed Tire Data Sheet and a copy of the Hunter RFV printouts from the VAS 6230 / Hunter GSP9700 ® Road Force Measurement system (Figure 2). The data sheet must be completed before a TAC ticket is opened. ® 3. After a TAC ticket has been created, send the VAS 6230 / Hunter GSP9700 Road Force Measurement system printouts and Tire Data Sheet to [email protected]. Failure to upload the Hunter RFV printouts will result in non-payment of the claim. The e-mail must include the following information: • VIN • Repair Order number or claim ID • Mileage (from Repair Order) © 2014 Audi of America, Inc. Page 3 of 8 All rights reserved.

Technical Service Bulletin • Dealer Code Prepare Tires for RFV Measurement: Temporary flat spots falsify the radial force fluctuation and must be driven out before the balance and the radial force are checked. Flat spots develop after a warm tire has cooled down after a stationary period of a few hours. The flat spots will vary based on the type, size, and make of the tire. If the vibration disappears after the tires are warmed up, the following repairs may not be successful. To eliminate temporary flat spots: 1. Test drive the vehicle a distance of at least 12-15 miles at various speed ranges (up to 62 mph). Some tires may require longer test drives to eliminate these temporary flat spots. 2. Raise the vehicle on a lift/hoist immediately after the test drive in order to check the balance and radial force before the tires cool down again. Tip: Flat spots are not a sign of a defect and therefore are not a warrantable condition. Tip: More information about flat spots is available in Elsa under Repair Manual >> Suspension, Wheels, Steering >> Wheel and Tire Guide >> 44 Wheels, Tires, Wheel Alignment >> Diagnosis and Testing >> Wheel and Tire Vibration >> Tire Flat Spots from Standing. Measure RFV: 1. Ensure that the tires are warm and the temporary flats spots have been eliminated. 2. Mount the wheels on the balancing machine, making sure that the contact surfaces of the flange and wheel are clean. Note: It is mandatory that the appropriate centering cone or collet (Figure 3) and a five-finger style clamping plate (Figure 4, A) are used when the wheel is being mounted on the balancer. A five-finger style clamp centers the wheel on the balancer in the same way the wheel is centered on the Figure 3. Example of collets (A and B), and centering vehicle (Figure 4, B). cone (C). An incorrect style of clamp could damage the wheel (Figure 4, C). © 2014 Audi of America, Inc. Page 4 of 8 All rights reserved.

Technical Service Bulletin Figure 4. Five-finger style clamping plate (A), wheel properly mounted with a five-finger style clamp (B), and wheel mounted using an incorrect clamping tool/method (C). Tip: Use adequate lubrication to ensure that tires are properly seated on the wheel. Do not use excessive lubricant, which may cause the tire to slip on the wheel, impacting the balance and road force values. Tip: Audi recommends using the correct collet when mounting the wheel/tire on the balancing machine. To order, please refer to Equipment Solutions (part number HUN2018451) 3. Perform a centering check to ensure the wheel has been properly mounted on the VAS 6230 / Hunter ® GSP9700 Road Force Measurement system. Tip: Do not use “Quick Match” mode; this mode does not measure radial force. Ensure that the “Smart Weight” balance feature is on. This feature will check both static (hop) and couple (wobble) vibrations to give the best possible weight and placement. Reduce RFV: 1. Optimize the radial forces: • Set the tire pressure of each wheel to 36 psi (2.5 bar). Measure, balance, and, if necessary, force match each wheel according to the instructions from the machine. Use 18lbs (80N) or less for the first harmonic vibration as the maximum. Note: If the first harmonic of the radial force of the tire that is the source of the vibration cannot be reduced to less © 2014 Audi of America, Inc. Page 5 of 8 All rights reserved.

Technical Service Bulletin than 18lbs (80N), and the tire is an original factory-installed tire, it should be replaced. Tip: After balancing the wheel/tire, perform a “Check Spin” to ensure balance values are consistent. If consistent values cannot be obtained, conduct a calibration of the machine (Figure 5). This operation is located in the “Logo” screen under “Calibration”. Figure 5. Back of balancer (A), calibration weight (B) Reinstall Wheel and Tire Assemblies: 1. Install the wheels according to VAS 6230 instructions for lowest vibration. The wheel/tire assembly with the lowest road force values should be installed closest to the driver: • Lowest road force value: Left front • Second-lowest road force value: Right front • Third-lowest road force value: Left rear • Highest road force value: Right rear Follow the instructions in Elsa under Repair Manual >> Running gear >> 44 wheels, tires, wheel alignment >> Installation of wheels/ tires/ tire pressure warning >> Instructions on wheel change/installation. 2. Adjust tire pressure. Refer to the owner’s manual for appropriate “normal load” tire pressure. The pressure displayed on the B pillar placard should only be used if vehicle is being operated at “full load”. 3. Test drive the vehicle at the speed at which the customer felt the vibrations to verify that the condition is repaired. © 2014 Audi of America, Inc. Page 6 of 8 All rights reserved.
