A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| A011542 2041787- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. DTCs are stored in the ECM. There may be soot buildup on the moveable elements of the pressure sensing glow plug (PSG). |
| Scheduled Maint | 2017-11-17. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. This document contains the scheduled maintenance intervals. The first scheduled service is due at 5,000 miles (8,000 km) or 1 year after delivery, whichever occurs first. Thereafter, all remaining scheduled services are due every 10,000 miles or 1 year after previous service, whichever occurs first. |
| A911522 2040406- | 2017-11-17. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). Supersedes Technical Service Bulletin Group 91 number 15-10 dated August 25, 2015. When the vehicle is started, the GPS location or vehicle direction indicated on the MMI navigation map does not match the vehicle?s actual location or direction of travel for a long period of time (often as long as 10 minutes). The issue occurs in open sky, with no large buildings obstructing the sky view. The issue is intermittent, but it can occur for long periods of time during a single day. The issue resolves itself intermittently. No DTCs related to the GPS antenna or MMI system are present. The vehicle is an A4 (including S4 and allroad variants), A5 (including Cabriolet, S5, and RS 5 variants), A6 (including S6 variant), A7 (including S7/RS 7 variants), A8 (including long wheelbase, S8, or W12 variants) or Q5 (including SQ5 and hybrid variants). (Q7 and Q3 vehicles are not affected by this condition. See TSB 2030465, 91 MMI3G+ GPS navigation location inaccurate or navigation takes a very long time to acquire location (Q7 or Q3) for Q7 and Q3 vehicles.) |
| A911520 2039515- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 15-07 dated July 28, 2015. The customer complains that the Audi connect online service in their 2012-2013 A6 or A7 vehicle only reaches 2G service. This bulletin applies only to model year 2012-2013 A6 and A7 vehicles. For other models, see TSB 2039476. This bulletin does not apply to model year 2014 or newer. Starting with model year 2014, the new telephone module was installed in production. Recently, T-Mobile (the service provider for Audi connect) has repurposed some of the GSM spectrum (3G on 2100Mhz band) to maximize 4G LTE coverage in certain metropolitan areas. Devices that do not support 3G service on the 1900MHZ band (including MMI main units of model year 2012-2013 A6 and A7 vehicles) will only receive 2G service when the switch is completed. The change currently only affects the markets listed above, but will affect other markets in coming years. This bulletin will be updated to include these markets as changes occur. |
| A511510 2009967- | 2017-11-17. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Supersedes Technical Service Bulletin Group 51 number 15-09 dated October 2, 2015. Instructions for vehicle inspection, protection removal, and detailing. |

| 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. |
| A461523 2034181- | 2017-11-17. Service bulletin. SERVICE BRAKES. Supersedes Technical Service Bulletin Group 46 number 15-02 dated February 9, 2015. The customer may report hearing brake noise from front or rear brakes. The customer may describe these noises as a squeal, squeak, grinding, groaning, thumping, or creaking. DO NOT use this TSB if there is another brake noise TSB applicable to the VIN. For additional information, refer to the Audi Brake systems brochure. Brake noise can be attributed to many causes. Brake discs or brake pads are close to or below their wear limit. New brake pads and/or discs have not been properly imbedded after installation. Aftermarket pads or discs are installed. There is debris (such as small stones, grit, road salt, or sand) between brake disc and brake pad. Discs are covered with rust. Rust can form when the vehicle has not been driven for a long period of time. Discs are grooved. There is chemical contamination on the braking surface of the brake disc due to wheel or tire cleaner being sprayed directly onto the brake disc. There are ?pad marks? on the brake disc as a result of brake pad material transferring to the discs. Pad marks can occur when a vehicle has been parked for long periods of time in a wet or snowy environment. |
| A441557 2022563- | 2017-11-17. Service bulletin. SUSPENSION. Supersedes Technical Service Bulletin Group 44 number 14-56 dated December 8, 2014. Customer feels vibration in the seat, vehicle floor, footwell, pedals, or steering wheel. This condition does not lead to any handling concerns or loss of vehicle control. Customer feels the vibration while driving at highway speeds from 55 ? 80 mph (88 ? 128 km/h). 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. 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. |
