GFF scan shows fault code- P172400 Starter Interlock Signal - short to Ground (GND) Sporadic, stored in the Transmission control module (02). Fault code- 00165 Transmission Park/Neutral Position Switch -F322- Incorrect Signal Sporadic, may also be stored in the Comfort module (46). Momentary loss of signal under very specific driving conditions causes fault to set.
A271214 2031145-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. complaints are reported by the customer regarding electrical features and functions in the vehicle. One or more warning lights on in cluster. The DIS or other displays in cluster are blank. MMI does not function. Windows do not function. LED indicators in various buttons inside the vehicle do not light up. The voltage regulator on the alternator can sporadically fail causing the electrical system to experience too high of voltage. As a result, the affected vehicle electronic components go in to high voltage protection and deactivate sensitive displays and indicators to prevent electrical damage. When an over voltage condition occurs the vehicle electronics and alternator are protected, thus there is no need to replace the entire alternator assembly.
A271215 2031145-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 27 number 12-14 dated October 12, 2012. Complaints are reported by the customer regarding electrical features and functions in the vehicle. One or more warning lights on in cluster. The DIS or other displays in cluster are blank. MMI does not function. Windows do not function. LED indicators in various buttons inside the vehicle do not light up. The voltage regulator on the alternator can sporadically fail causing the electrical system to experience too high of voltage. As a result, the affected vehicle electronic components go in to high voltage protection and deactivate sensitive displays and indicators to prevent electrical damage. When an over voltage condition occurs the vehicle electronics and alternator are protected, thus there is no need to replace the entire alternator assembly.
A481232 2029282-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; STEERING. Supersedes Technical Service Bulletin Group 48 number 12 ? 24 dated May 8, 2012. The symbol for dynamic steering is illuminated in the instrument cluster. A DTC for overload or overuse is stored in the active steering control module (J792), address word 1B.

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.
A371276 2029305-2017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 37 number 12-74 dated November 28, 2012. Customer may report harsh downshifts while braking or harsh 1-2 upshift under acceleration. Further TCM software calibration to improve shift concerns.
A371277 2029027-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Supersedes Technical Service Bulletin Group 37 number 12-67 dated September 28, 2012. Customer may report gearbox warning light on. In some cases after starting vehicle and placing into gear the vehicle would not move. After key cycle the vehicle drives without restriction. The entry P060A00 with DFCC 8692 can be logged in the following situation: After selecting Neutral, a driving mode (D or R) is selected within one second while the vehicle rolls (at under 2 mph). This can, for example, happen when maneuvering the vehicle into or from a parking area. The entry P060A00 with DFCC 8694 can be logged when quickly changing from P-N because of a low diagnosis threshold. The entry P060A00 with DFCC 12480 can be logged because of a low diagnosis threshold when changing gear with the tip function.
A871238 2032204-2017-11-08. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. The customer may claim that when adjusting the climate system temperature or air distribution that noises can be heard from the regulator motors. There may be various DTC? s stored in 08 ? Climate Control Module. Due to a production issue with the regulator motors at the supplier, audible noises from the regulator motors could develop. The adjustment strategy of the regulator motors must be changed by way of a software update.
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.
A571402 2022032-2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 57 number 13-97 dated October 29, 2013.

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.
A371429 2029027-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 37 number 13-17 dated September 11, 2013. Customer may report transmission warning light is illuminated. In some cases, the vehicle will not move after being started and placed into gear. After key cycle, the vehicle drives without restriction. DTCs are stored in the transmission control module (TCM). If DFCCs do not match exactly, this TSB does not apply. The DTCs are stored due to an issue with the transmission control module software.

The ignition key cannot be removed even though the gear shifter is in Park (P). The vehicle is mechanically in the Park position, but this is not recognized electronically. The gear shifter cannot be moved from the Park position. On vehicles with Audi advanced key, the vehicle cannot be locked by remote control after the engine has been switched off. DTC 00230 may be sporadically stored in the vehicle authorization system control module. The Park position of the gear shifter is sporadically not recognized, which causes the ignition key to not be cleared and prevents the vehicle from being locked.
A371422 2028985-2017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 37 number 13-01 dated April 24, 2013. Transmission warning may appear in instrument cluster. After ignition cycle, the warning message is no longer present. DTC P074100 (Torque Converter Clutch Circuit Performance) or ?Stuck Off? is stored in transmission control module (TCM), J217 (address word 03). The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks.
Customer Letter2017-11-08. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Audi has determined that, under specific conditions, the turbocharger could malfunction and may cause the Malfunction Indicator Lamp (MIL) on the instrument cluster to illuminate due to the presence of specific fault codes caused by this component. The MIL is part of your on-board diagnostic system. Please refer to your owner's manual for additional information about the MIL. In some locales, an illuminated Malfunction Indicator Lamp could cause your vehicle to fail an IM emissions inspection, and your vehicle registration application could be denied. Please be aware that other conditions (unrelated to the issue described in this letter) may cause the MIL in your vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions. Dealers will diagnose and replace a faulty turbocharger if necessary, at no cost to you as long as the vehicle remains within the time and mileage limits of this warranty extension.
A971443 2036764-2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 97 number 14-42 dated March 31, 2014. The MIL is on. Vehicle will not start. DTC P068A00 is stored in the ECM. The motronic engine control module power supply relay, J271, is not functioning properly. Because the J271 relay controls battery voltage (Terminal 30) via a ground signal sent from the ECM, numerous faults can occur in multiple control modules when it is not functioning properly.
A911437 2030947-2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 13-92 dated July 16, 2013. The customer complains that when he or she is trying to place a phone call from the vehicle while using a Bluetooth®-connected phone, the phone call disconnects before it begins and an error shows on the MMI display. The message may be "Function not supported" or "Network error". The customer is using a phone with the Android operating system. In addition, Skype®, or another network-based communication software, is installed on the phone. Call can be placed directly from the phone without a problem. When the phone receives the request to place a call from the vehicle, a prompt appears on the phone asking the user to choose how the call should be placed. If the prompt is ignored, the MMI system disconnects the call because it assumes that the phone is not responding.
A901449 2029781-2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 90 number 13-40 dated September 9, 2013. The driver information system (DIS) display screen is completely blank or appears to be all white. The condition is intermittent and the DIS can function normally when the key is cycled off and back on. This condition only affects vehicles with the highline instrument cluster. The issue is attributed to incorrect software for clusters with the Hitachi display screen.
A271424 2025360-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Supersedes Technical Service Bulletin Group 27 number 12-12 dated February 28, 2012. Customer may report that the vehicle does not start due to a discharged battery. The vehicle has either a battery diagnostic management control module or a battery energy management control module. This TSB provides basic diagnosis steps for discharged batteries, general tips for working with batteries, and system verification steps to ensure that the vehicle is configured correctly.
A171449 2028440-2017-11-08. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 17 number 12-26 dated January 20, 2012. When the vehicle is completely refueled, the vehicle range (?distance to empty?) that is displayed is different than the vehicle range that was displayed the last time the vehicle was completely refueled. The displayed vehicle range drops inconsistently. After the vehicle is refueled, the displayed vehicle range does not change for a long period of time. When the vehicle is driven on hilly roads for a long period of time, the displayed vehicle range suddenly changes by a significant amount. There are no DTCs related to fuel senders stored in the instrument cluster control module, J285 (address word 17). This condition does not involve or affect the accuracy of the fuel level indicator, but only the estimated distance to empty display on the on-board computer.
