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.

DTCs are stored in the ECM. The quality of the auxiliary exhaust gas recirculation (EGR) cooler modules manufactured within a certain timeframe may be inadequate. The vacuum actuator diaphragm may have leaks. A faulty auxiliary EGR cooler will trigger a P310E fault. Faulty operation of the auxiliary EGR cooler can also trigger the P040B fault, but there is no issue with the temperature sensor.
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.
A191453 2039018-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. A small amount of dry or crusted coolant is seen on the coolant pump housing. The coolant level warning is not on. A minor coolant leak is possible during the break-in phase of the coolant seal on the coolant pump. The dry coolant marks are normal.
A171453 2038129-2017-12-05. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 17 number 14-50 dated August 15, 2014. A check with the engine oil service dipstick T40178 is necessary, but the adjustment values for the dipstick are not available in the Elsa repair manual.

A011498 2038166-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. The engine warning light is on after engine replacement. The engine is not running roughly. However, fault codes are stored in the engine control module (ECM). The fault codes occur at light load, between 8% and 14% accelerator pedal position. The programmed values for the misfire adaption are not automatically reset when the memory is deleted. The adaption must be reset after the engine is installed.
A011497 2033001-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 14-89 dated August 19, 2014. MIL on. DTCs are stored in the engine control module. 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.
A011324 2033001-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 13-01 dated May 29, 2013. MIL on. DTCs are stored in the engine control module. 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.
A011327 2033768-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 13-89 dated May 2, 2013. MIL on. A cylinder misfire fault (DTC P0301 - P0306) with DTC P130A is stored in the engine control module (ECM), J623 (address word 01).
AWA-13-072017-12-05. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. As part of Audi's ongoing commitment to our environment, Audi is extending the Emissions Control Systems Warranty to cover cleaning of the engine cylinder head secondary air ports to remove carbon buildup under specific conditions to 10 years or 120,000 miles, whichever occurs first, from the vehicle's original in-service date for certain 2009-12 Model Year Audi vehicles with 3.2L engine, and certain 2009-2013 Model Year Audi vehicles with 3.0T engines. The vehicle's original in-service date is defined as the date the vehicle was delivered to either the original purchaser or the original lessee; or if the vehicle was first placed in service as a "demonstrator" or "company" car, on the date such vehicle was first placed in service. The warranty extension is fully transferable to subsequent owners. Audi has determined that under certain driving conditions, carbon buildup can occur in the engine cylinder head secondary airports. Due to the presence of specific fault codes caused by this carbon buildup, the Malfunction Indicator Lamp (MIL) on the instrument cluster may illuminate. The MIL is part of the on-board diagnostic system. In some locales, an illuminated MIL could cause the vehicle to fail an IM emissions inspection, vehicle registration application could be denied. Audi will diagnose, and if necessary clean the engine cylinder head secondary air ports to remove the carbon buildup at no cost to the customer as long as the vehicle is within the time and mileage limits of the warranty extension. This warranty extension covers only the diagnosis and cleaning of the cylinder head secondary air ports to remove the carbon buildup. Reimbursement is applicable only to the repairs described in this Warranty Bulletin.
Customer Letter2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Audi has determined that, under certain driving conditions, carbon buildup can occur in the engine cylinder head secondary air ports. Due to the presence of specific fault codes caused by this carbon buildup, the Malfunction Indicator Lamp (MIL) on the instrument cluster may illuminate. The MIL is part of your on-board diagnostic system. Please refer to your owner's manual for additional information about the MIL. In some locales, an illuminated Malfunction Indicator Lamp could cause your vehicle to fail an IM emissions inspection, and your vehicle registration application could be denied. Please be aware that other conditions (unrelated to the issue described in this letter) may cause the MIL in your vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions.
Dealer Letter-Da2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. We would like to inform you of an upcoming Emissions Service Action 23L2. This service action in in regards to the differential pressure sensor/ECM software update.
