| 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. |

Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure. |
| A011259 2027732- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 24 number 12-44 dated September 17, 2012. MIL on. DTC P0456 (very small EVAP leak) stored in ECM. No leaks found in the EVAP system. Software update needed. |
| A171233 2030197- | 2017-11-08. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 10 number 12-09 dated October 1, 2012. Engine oil consumption too high. 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. Under certain driving conditions internal engine pressure conditions in the 3.0 TFSI engine can negatively influence the rate of oil consumption. This condition can occur while the vehicle is operated in metro driving conditions, for example: Stop and go traffic with extended idle periods. |
| A571280 2029151- | 2017-11-08. Service bulletin. EQUIPMENT; STRUCTURE:BODY:DOOR. Supersedes Technical Service Bulletin Group 57 number 12-65 dated May 14, 2012.

| A151225 2031085- | 2017-11-08. Service bulletin. ENGINE; ELECTRICAL SYSTEM. MIL on. DTCs for the cam actuators are stored in ECM memory. After the activation of the cam actuator to change to the other cam profile, the pin of the actuator is pushed back in by the cam. This is confirmed by a voltage impulse, which is registered by the engine control unit and confirms the operation. If this does not happen, or not at the right time, a DTC "implausible signal" is saved in ECM memory. Check the distance of the pin tip of the cam actuator for valve lift system to the camshaft when it is not operated with a gauge. The measurement of the tip to the basic camshaft circle outside of the groove must be taken. If this measurement is 0.9mm, the actuator 06E103697J must be installed. The actuator 06E103697J must only be used, if the measurement is 0.9mm or bigger. |
