A871342 2020124-2017-11-17. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Supersedes Technical Service Bulletin Group 87 number 12-37 dated November 16, 2012. Air conditioning is inoperative. The HVAC blower functions normally. Battery discharged; however, when charged, there is no bus silence when vehicle ignition is off. The A/C pressure/temperature sensor, G395, leaks refrigerant. This causes sensor G395 to show an incorrect or implausible value when reading MVBs. An incorrect signal or a low refrigerant level in the system can cause the air conditioning compressor to deactivate. The LIN cable connecting the vehicle electrical system control module, J519, to sensor G395 is pinched or cut. This affects the A4/S4, A5/S5 Coupe and Cabriolet, and Audi Q5 vehicles. The A6 and A8 are not affected by this type of failure. The pressure sensor G395/G65 sends an incorrect signal that prevents bus silence and the battery is discharged. Sensor G395 is a LIN slave of the vehicle electrical system control module. The vehicle electrical system control module transfers the information provided by the sensor via the comfort data bus to the climate control module, J255.

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.
A371268 2028561-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 37 number 12 ? 52 dated May 31, 2012. There is no customer complaint about the gearbox. The gear lever display flashes. The message "gearbox problem, journey can be continued with restrictions" is shown. The entry P0605 or P17EC is logged under the diagnosis address 81- Selector lever.

The self-leveling system cannot be adjusted any more with the MMI. The compressor for the self-leveling system continues to run after switching off the engine and locking the vehicle. DTCs may be stored. Because of poor performance or failure of the compressor for air suspension, the vehicle position cannot be adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the warning light. Drivability is not affected.
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.
A481232 2029282-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; STEERING. Supersedes Technical Service Bulletin Group 48 number 12 ? 24 dated May 8, 2012.

A571276 2030580-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 57 number 12 ? 68 dated August 20, 2012. The vehicle cannot be started sporadically. The yellow gearbox warning light may be illuminated. Entries are logged in the respected modules. The remote key the customer is using is transmitting incomplete immobilizer information to the vehicle; resulting in the condition.
A901235 2030903-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; LANE DEPARTURE. Supersedes Technical Service Bulletin Group 90 number 12 ? 34 dated September 21, 2012. When driving, various warning lights come on, sometimes with restricted functions in the electric system. These complaints only occur together with complaints or a failure of the MMI 3G+ infotainment system. After an ignition cycle the complaint is typically gone; therefore, it may not be reproducible. Sporadic DTCs may be present for communication errors, restricted functions, or missing/incorrect messages. If the MMI 3G+ has an issue, the data bus control unit (Gateway) tries to maintain the communication to the MMI. The load on the unit is so high that other messages on the bus systems cannot be processed any more. As a remedy, modified software can be installed on the Gateway which does not communicate to the MMI 3G+ when it is unavailable.
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.
A911264 2031367-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.; EQUIPMENT. CD or DVD disks do not automatically change from one to the next in the external CD or DVD changer. The CD and DVD changer have different operating concepts. MMI3G: Disks in the CD changer are always automatically changed from one to the next. MMI3G+ (with Audi connect): Disks in the CD changer are automatically changed from one to the next, but this operation is disabled when the Repeat option is turned on in the Media Settings menu. By default (MMI factory default setting) the repeat option is set to ? Off?. DVD changer (A8 only): Disks in the DVD changer can only be changed manually.
