Reference-Oil Ca2017-11-03. Service bulletin. ENGINE; EQUIPMENT; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. This document contains the Audi oil capacity chart.
A871346 2035582-2017-11-03. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ENGINE AND ENGINE COOLING. 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.
A171347 2035463-2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13-44 dated October 22, 2013. 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, and the ambient temperature and road conditions. Additional factors include the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. Utilizing the advanced sensor technology integrated in models equipped with the 3.0 TFSI engine, it is possible to measure oil consumption electronically via a Guided Function test plan. If the electronic oil consumption test is not available for this model, perform the test with the conventional scale/oil weighing method. See TSB 2018550 for instructions for the conventional scale/oil weighing method.
A871345 2024644-2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS. Supersedes Technical Service Bulletin Group 87 number 13-41 dated May 30, 2013. Moisture in the driver or front passenger foot well. Due to a faulty and/or incorrectly installed condensation drain hose, condensation from the evaporator could enter the front foot well areas through a gap between the body and the sealing surface of the drain hose.
A101310 2018288-2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 10 number 10-02 dated September 14, 2010. Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the vehicle's engine experienced a serious mechanical problem, it is possible that small pieces of metal debris resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses, exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler. If these pieces are not removed prior to the installation and operation of the replacement engine, the pieces may be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage.
A011331 2035348-2017-10-31. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ENGINE AND ENGINE COOLING. MIL on. Customer may report loss of performance. DTC P008700 (fuel rail pressure too low) may be stored in the engine control module, J623 (address word 01). Under extreme driving conditions with the A/C compressor switched off (e.g., long idle periods or extended stop-and-go traffic), high temperatures can build up in the fuel rail and may lead to fluctuations in fuel pressure, possibly causing DTC P008700 to be stored. Coolant temperature above 102?C in the freeze frame data can be an indicator of those extreme driving conditions.
A201327 2035073-2017-10-31. Service bulletin. ENGINE. MIL on. DTC P045600 (EVAP System Leak Detected NVLD (very small leak)) is stored in the engine control module (ECM), J623 (address word 01). Drivability is not affected.
