Supersedes Technical Service Bulletin Group 87 number 10-07 dated September 2, 2010. The A/C system is not cooling as desired in hot weather areas. The following are suggestions to achieve maximum cooling efficiency in hot weather areas.
A011255 2030192-2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. MIL light on. P2015 sender of intake manifold flap position/air flow control, implausible signal P2020 sender of intake manifold flap position, intake manifold flap 2, implausible signal. Engine may have reduced performance without significant loss of power or stalling. Check service history to see if the improved ? B? suffix V157 Intake Flap motor has already been installed previously; if yes, only replace the potentiometer seals as described below. The fault entry is made because a linkage of the intake manifold flap adjustment sticks. This is caused by deformed oil seal behind the potentiometers.
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.
A431211 2018765-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 43 number 12-08 dated February 2, 2012. 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.
A001463 2033576-2017-11-08. Service bulletin. ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Supersedes Technical Service Bulletin Group 00 number 13-49 dated May 14, 2013. Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. When an unapproved aftermarket speed-filling device is used to add oil to the engine, the increased oil flow rate may force oil into the intake manifold or combustion chamber, creating the potential for engine damage.
A191450 2025303-2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 13-41 dated June 20, 2013. Discontinuation and mixing of Audi-approved engine coolants. G11, G12, and G12+ coolants have been replaced by an improved version. G12++ coolant (for service available) has been introduced in MY 2005 for all engines. G13 has been introduced in MY 2008 as factory filling and service.
A011457 2015106-2017-11-08. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 24 number 11-06 dated December 7, 2011. The MIL is on. DTCs are stored in the ECM. Due to fuel intrusion into the low-pressure system fuel pressure sensor (G410), a false signal may be sent to the controller, resulting in a reading that is out of tolerance. Comparing Measured Value Block 103 with 106 is not an accurate method for diagnosing G410. In order to diagnose G410 accurately, use a mechanical gauge and compare results with the low-side fuel pressure Actual Value in Measured Value Block 103.
