Service bulletins for the 2010 Audi A4

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

A171560 2027731-2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 15-54 dated January 29, 2015. 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 2.0 TFSI engine can negatively influence the rate of oil consumption. This condition can occur while the vehicle is operated in metro driving conditions.
A171557 2010043-2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13-35 dated January 9, 2013. This bulletin lists engine oils that meet Audi oil quality standards (VW 501 01, 502 00, 505 00, 505 01, and 504 00/507 00).
A101511 2018288-2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 10 number 13-10 dated September 5, 2013. Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the 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 metal debris pieces are not removed prior to the installation and operation of the replacement engine, they could be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage.
