A871567 2041717-2018-02-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Customer may report poor performance of A/C system or that the A/C system is inoperative. Any replacement of A/C compressors must include an ODIS GFF test plan confirming a malfunction of the A/C system with documentation of the recovered refrigerant volume.
A871569 2020124-2018-02-05. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 14-49 dated April 25, 2014. 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 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.
A871447 2010146-2017-12-14. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 12-27 dated April 24, 2012. There is an unpleasant, musty odor coming from the heating and ventilation system. The odor usually occurs when the vehicle has been sitting unused for five hours or more. The odor usually occurs within 20 to 60 seconds after the vehicle is started. Condensation, which is a normal condition in all A/C systems, can cause a musty odor. If the odor is noticeable in the vehicle when the engine is not turned on, the cause may be mold and mildew in the passenger compartment, and not be related to the A/C system. All other possible sources of the odor must be investigated before this bulletin can be performed.
A901451 2021151-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 91 number 12-63 dated October 4, 2012. The customer may report flickering of the dash insert lighting, of the A/C control panel lighting, or of the inside light. The condition occurs when the accelerator is pressed while the vehicle is in P or N, or when the vehicle is shifted down when moving downhill. Only vehicles with PR number 8GH may be affected. When high electricity consumers are switched off when 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, causing the lights to flicker.
A871459 2029136-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 14-52 dated July 14, 2014. The customer may report that after a specific temperature is selected 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. Perform a test drive with the customer both before and after this repair to ensure a thorough understanding of the customer's concern. DTCs for mechanical malfunction of one or more air distribution control motors may be stored in the air conditioning/heating control unit, J255 (address word 08).
A871458 2035582-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-46 dated October 21, 2013. The A/C Compressor has been diagnosed as faulty and will be replaced under warranty. When performing replacement of an A/C Compressor under warranty, the amount of refrigerant and oil recovered must be documented.
A801304 2033806-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM:WIRING. Supersedes Technical Service Bulletin Group 80 number 13-03 dated May 13, 2013. Malfunction Indicator Lamp is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. "Limp Home" mode is active. Faults are stored in the transmission control module. Coolant loss is found from one or more control valves: N82, N509, or N488. Coolant may have migrated into the wiring harness through the connector and into various control units. Climate system heating performance is insufficient due to coolant loss, or due to a faulty N82 control valve. Inspection of the coolant control valves N82, N509, or N488 reveals the presence of coolant inside the electrical connector. The connectors, wiring harness, and/or connected control units may have been damaged from exposure to coolant.
A851319 2035000-2017-12-05. Service bulletin. EQUIPMENT; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Various "whistling" noises are heard from the blower motor when it is running, particularly when it is running at lower fan speeds. The noises may be intermittent, and may depend on the outside temperature, the position of the flaps, etc. The noises are subtle, and they may not be heard if the audio system is on or if the vehicle is moving. The noises may be caused by a section of the noise insulation on the heating and air conditioning unit.
A871344 2020124-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-43 dated July 12, 2013. Air conditioning is inoperative.
