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.

| A901238 2032113- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. The customer may state that the outside ambient temperature display is incorrect. To achieve a smoothening effect of the displayed outside ambient temperature, the value shown does not instantaneously follow the temperature sensor measurement. The display will not change faster than 4° F (2° C) per minute. This concept applies to both falling and rising temperatures. A programming strategy is also implemented to avoid incorrect readings on a parked vehicle, due to the temperature sensor being affected by outside influences such as radiant heat from the engine bay, elevated road surface temperatures, etc. |

| Update Bulletin | 2017-11-08. Service bulletin. STRUCTURE; ELECTRICAL SYSTEM. Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults. This Update is in effect until removed. Procedure is valid only for vehicles that show the 37H5 code in the Elsa Campaign/Action Information screen on the day of repair. Vehicle must be within the New Vehicle Limited Warranty. Procedure must be performed within the allotted time frame stated in this Technical Service Bulletin. Procedure must be performed on applicable vehicles in dealer inventory prior to sale. Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults. |
| Dealer Letter - | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults. Drain and flush the gearbox and replace the multitronic unit. |
| A941442 2034735- | 2017-11-08. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Supersedes Technical Service Bulletin Group 94 number 13-25 dated July 24, 2013.

Workshop found no visible external force marks (from accident or debris impact) are present, one or both sides may be affected, and the vehicle is not equipped with halogen headlights. The production process causes stress on the headlights from the bumper, as well as torsional force from installation. The moisture is an optical condition that does not affect the function or performance of the headlights, and it will not lead to corrosion or damage of the internal headlight parts. |
| A641433 2029714- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 64 number 12-22 dated July 5, 2012. After one or both of the front door control units (J386/J387) is replaced, one or both of the rear door control units (J3888/J389) cannot be coded or parameterized via an SVM specified vs. actual comparison (spec/actual). The parameter data in the software coding container has changed for the front and rear door control units. As a result, an SVM code is required to update the parameter data for any replacement control unit. Simply running an SVM spec/actual will not code nor update the parameter data in the new replacement control unit. A hardware change suggestion will be provided when an SVM spec/actual is executed. An additional hardware replacement is not required. |
