| A481566 2034351- | 2018-04-02. Service bulletin. STEERING. Supersedes Technical Service Bulletin Group 48 number 15-65 dated March 23, 2015. Customer may report hearing creaking or squeaking noise from the steering column when steering slowly (the noise can be duplicated while the vehicle is stationary if the steering wheel is turned slowly). The noise may get louder at higher temperatures or when the vehicle is driven for a longer period of time. The noise comes from the sealing sleeve/steering column opening on the bulkhead.

| A4015462024687-4 | 2018-02-05. Service bulletin. STEERING; EQUIPMENT. Supersedes Technical Service Bulletin Group 40 number 12-25 dated August 7, 2012. Steering wheel oscillation at highway speeds (typically between 70 and 85 mph). No vibration in the seat surface or other vehicle components. Audi original equipment tires are installed on the vehicle. If necessary, TSB 2022179 has been completed and the 1st harmonic of radial force of every tire and wheel assembly is below 18 lbs. at a tire pressure of 36 PSI (2.5 bar). Ride disturbances such as uneven roads, wheel imbalance, impermissibly high radial forces of the tires, or other rotating components on the front of the vehicle are transmitted to the steering wheel as a vibration or oscillation. |

| A461525 2022584- | 2017-11-17. Service bulletin. STEERING: STEERING WHEEL/HANDLE BAR; SERVICE BRAKES, HYDRAULIC. Supersedes Technical Service Bulletin Group 46 number 14-86 dated July 14, 2014. DO NOT use this TSB if there is another TSB for same concern applicable to the VIN. This TSB is only intended for diagnostic purposes and does not serve as a guideline for determining warrantable conditions. Customer may report that the steering wheel vibrates or pulsates when the brakes are applied. driving style, environmental conditions, and service history of the vehicle. Additionally, as brake pads and discs wear, their dampening ability is reduced. Disc thickness variation (DTV) is a common condition that contributes to brake pulsation. DTV occurs when the two braking surfaces of the brake disc are no longer parallel to each other. This condition cannot be accurately measured with normal workshop tools. |
| A401548 2042603- | 2017-11-17. Service bulletin. STEERING. When the vehicle is driven between 35 mph and 75 mph, a noise can be heard in the front of the vehicle. The customer may say that the noise is coming from the steering column area, and may describe the sound as buzzing, humming, whistling, whining, grinding, howling, and/or droning. The best way to understand the complaint is to discuss it with the customer. Faulty wheel bearing(s) may cause the noise. |
