A871343 2020124-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-42 dated June 11, 2013. 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.
A871340 2029136-2017-11-17. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ENGINE AND ENGINE COOLING:COOLING SYSTEM. Supersedes Technical Service Bulletin Group 87 number 12-35 dated November 14, 2012. The customer may report that after selecting a specific temperature in AUTO mode, the resulting airflow and temperature are uncomfortable. The customer complaint is subjective and may be difficult to diagnose during a road test. Please test drive with the customer before as well as after this repair to ensure a thorough understanding of the customer's concern. At certain outside temperatures and operating conditions, the temperature in the passenger compartment fluctuates. This is caused by the unventilated sensor in the air conditioning control panel. There may also be DTCs stored for mechanical malfunction of one or more air distribution control motors in (08) air conditioning/heating control unit.

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.
A871452 2029136-2017-11-08. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 14-48 dated March 10, 2014.
