A171232 2018550-2017-11-08. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 17 number 12 - 31 dated August 30, 2012. Oil consumption measurement - Repair Authorization (CA). In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner's Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil.
A461226 2031135-2017-11-08. Service bulletin. LANE DEPARTURE; PARKING BRAKE; ELECTRICAL SYSTEM. The customer may state the yellow warning for electric parking brake (EPB) appeared once in the instrument cluster, but the warning turned OFF after cycling the ignition and there have been no additional occurrences. The customer may state the adaptive cruise control (ACC) was inoperative once, but resumed operating properly after cycling the ignition and there have been no additional occurrences. DTC is stored in the EPB module. Internal code Param_InterFaultID 24 or 25 may be in the extended environmental conditions. The concern is due to a software glitch in the EPB control module. Concerns related to this software glitch can only occur once. Replacing the EPB module may cause an additional occurrence.
A481233 2027779-2017-11-08. Service bulletin. STEERING. Supersedes Technical Service Bulletin Group 48 number 12-21 dated March 30, 2012. After replacing the electromechanical steering with the control unit J500, the unit cannot be coded via SVM spec/actual.
A571274 2027494-2017-11-08. Service bulletin. EQUIPMENT; STRUCTURE. Supersedes Technical Service Bulletin Group 57 number 12 ? 71 dated September 17, 2012. The outer door seals have become partially detached. Loss of adhesion between the door structure and door seal due to a flaw in the attachment process in production.

The outer door seals have become partially detached. Loss of adhesion between the door structure and door seal due to a flaw in the attachment process in production.
A911262 2024323-2017-11-08. Service bulletin. BACK OVER PREVENTION. Supersedes Technical Service Bulletin Group 91 number 10 - 60 dated September 28, 2010. Parking aid sporadically warns of obstacles when none exist. Parking aid is inoperative or provides constant warning. Various parking aid sensor fitting issues. Environmental conditions.
A911263 2021151-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 91 number 11 ? 83 dated April 15, 2011. The customer may report that the illumination of the dash insert, the air conditioning control panel or the inside light flickers when briefly pressing the accelerator in P or N or when shifting down while driving downhill. Only vehicles with PR number 8GH may be affected. When high electricity consumers are switched off and the battery is fully charged, the energy generated by the alternator is sometimes too great for the power system to absorb. This may lead to briefly increased voltage, and the lights mentioned above may briefly flicker. This characteristic is caused by the alternator design and is a normal condition of the vehicle.
A941290 2030956-2017-11-08. Service bulletin. EXTERIOR LIGHTING. Supersedes Technical Service Bulletin Group 94 number 12 ? 88 dated September 25, 2012. The turn signal indicator lens is inoperative without any damage from outside influence. Cracks have formed in the lens and as a result condensation can be seen behind the lens. The turn signal lens can crack due to the high amount of tension in the side mirror housing. The tension is due to improper installation of the mirror at the factory and is not a defect in the mirror housing. Replacing the mirror housing will not affect this condition.
A941292 2012749-2017-11-08. Service bulletin. EXTERIOR LIGHTING. Supersedes Technical Service Bulletin Group 94 number 11-52 dated October 11, 2011. Condensation is visible on the inside of the headlight, taillight, fog light, side marker light, front turn signal, daytime running lights, or third brake light lens. Damp air settles on the inside of a cold lens, which creates condensation. The headlight circulation system allows air from the outside to flow through the headlights. This open waterprotected ventilation system (needed for pressure compensation) creates different climate zones in the headlight: very warm areas, where the lens is warmed up by the light, and relatively cool areas, where the lens is cooled own by the air flow. Considerable differences in humidity and temperature between the inside and the outside of the headlights, even while driving, can lead to condensation. This is especially true in cold and wet weather, but it can also happen after a car wash, after steam cleaning the engine or the front end, with overnight temperature changes, etc. This phenomenon is more visible on lenses made of clear glass than on lenses with patterns. The moisture does not affect the headlight function (light performance) and does not lead to corrosion or other damage to headlight parts.
A961243 2031095-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Audi Side Assist deactivates itself immediately following the engine starting. The DTC entry "Control unit 2 for lane changing assistant - restricted function because of low voltage, sporadic" is logged in the control unit ?3C ? Lane Change Assistant?. The control unit ?3C ? Lane Change Assistant? checks voltage after each engine on cycle and during this check the voltage can be incorrectly reported which causes the DTC to set.

The plastic stop on the adapter of the fresh air blower motor is damaged in production. As a result, the blower moves within its housing. This allows the blower impeller to make contact with the blower motor housing.
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.
