DTC P0491 and P0492 \(Secondary Air System Insufficient Flow, Bank 1/2\) are stored at the same time. Mileage is greater than 15,000 miles. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.

Supersedes Technical Service Bulletin Group 19 number 13\-44 dated July 18, 2013. Customer may report coolant leaking from the engine area. The leak can be traced to the connection of the water pump and the hose leading to the heater core. The seal ring is not the cause of the leak.
- [A171346 2030197\-](/bulletins/10121488.md), 2017-10-31, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13\-45 dated October 23, 2013. Customer complains of excessive oil consumption. 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 can occur while the vehicle is operated in city driving conditions, for example: stop and go traffic with extended idle periods.
