A001349 2033576-2017-12-05. Service bulletin. ENGINE. 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.
Campaign Circula2017-12-05. Service bulletin. ENGINE; EQUIPMENT. Part quantity updated on SAGA sheet. The Owner?s Manual in certain 2013 model year Audi vehicles was printed with incorrect numerical callouts in the engine compartment overview artwork. This could cause confusion for anyone who relies on this information in order to identify key components within the engine compartment.
