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. Because of a system change, the adjustment values for the service dipstick T40178 were removed from the repair manual.
A011492 2033224-2017-12-05. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 01 number 13-28 dated September 12, 2013. If a model year 2015 Q5 TDI, A6 TDI, A7 TDI, or A8L TDI clean diesel (engine code CPNA or CPNB) requires diagnosis or repair of the engine, diesel fuel delivery, exhaust after-treatment (SCR/AdBlue and emissions) systems, or transmission, a Repair Authorization is necessary prior to repair. This also applies to any messages related to AdBlue shown in the DIS. These procedures are mandatory until further notice. Routine maintenance, PDI, and repair of other systems do not require prior authorization or a TAC ticket. Any repairs related to the engine, diesel fuel delivery, exhaust after-treatment (SCR/AdBlue or emissions) systems, or transmission completed without Repair Authorization via a Technical Assistance Center (TAC) contact will not be reimbursed.
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.
A011386 2033630-2017-11-17. Service bulletin. EQUIPMENT:ELECTRICAL; ENGINE. MIL on. Rough idle. DTCs are stored in the Engine Control Module (ECM), J623 (address word 01). Engine may have reduced performance without significant loss of power or stalling. Because there are a number of different misfire faults (unrelated to ignition coil operation) that could cause the MIL to illuminate, proper Guided Fault Finding (GFF) misfire diagnosis must be followed before any ignition coils are replaced.
A191562 2025303-2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 15-61 dated July 7, 2015.

This is an update to the November 3, 2015 communication where Volkswagen Group of America, Inc. issued a stop sale order for all 2013-2016 model year Audi vehicles equipped with a Gen II 3.0 liter V6 TDI engine. This was in response the notice received from the U.S. Environmental Protection Agency and California Air Resources Board of an investigation related to certain emissions compliance matters impacting certain 3.0 liter V6 TDI engine vehicles. Audi continues to actively cooperate with the relevant authorities to resolve the November 2, 2015 EPA notice of violation.
A001463 2033576-2017-11-08. Service bulletin. ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Supersedes Technical Service Bulletin Group 00 number 13-49 dated May 14, 2013. 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.
