Service bulletins for the 2013 Audi S8

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.

A011718 2038045-2018-02-05. Service bulletin. ENGINE AND ENGINE COOLING. This technical service bulletin provides instructions for replacing the coolant thermostat with a new part number to resolve a stored DTC.
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. Because of a system change, the adjustment values for the service dipstick T40178 were removed from the repair manual.
A211419 2034999-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. Supersedes Technical Service Bulletin Group 21 number 13-17 dated August 16, 2013. On 4.0l bi-turbo FSI engines, the pipe on the impeller side of the bank 2 turbocharger looks discolored when compared to the pipe on the bank 1 turbocharger.
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.
A211317 2034999-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. On 4.0l bi-turbo FSI engines, the pipe on the impeller side of the bank 2 turbocharger looks discolored when compared to the pipe on the bank 1 turbocharger. The crankcase breather is only connected to the bank 2 turbocharger inlet. Blow-by gases from the crankcase breather discolor the pipe. This is a normal condition.
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 -2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. This communication is to inform you of upcoming Update 24Z6. On Audi vehicles with a 3.0L TFSI engine produced during a certain period, it is possible that the membrane on the vacuum actuator for the intake manifold flaps may tear. As a result, the intake manifold flaps do not function and the engine indicator light turns on. Install new manifold actuators.
Update Bulletin2017-12-05. Service bulletin. ENGINE. A quality package has been defined for Audi vehicles with 4.0L TFSI engine manufactured within a specific period. This Update is in effect until removed. Procedure is valid only for vehicles that show the 19J1 code in the ElsaWeb Campaign/Action Information screen on the day of repair. Vehicle must be within the New Vehicle Limited Warranty. Procedure must be performed within the allotted time frame stated in this Technical Service Bulletin. Procedure must be performed on applicable vehicles in dealer inventory prior to sale. A quality package has been defined for Audi vehicles with 4.0L TFSI engine manufactured within a specific period.
A011369 2028344-2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 12-57 dated October 29, 2012. Noises/inconsistent engine operation after cold start during the catalyst heating phase. The customer may interpret this engine roughness as misfiring. To comply with the legal requirements on exhaust gas emissions according to the LEV-1 and LEV-2 standards, a high exhaust gas quality must be ensured. The necessary catalyst only operates at a temperature over 300°C (572°F). To achieve this, the catalyst is heated up. The catalyst heating phase is achieved by a late ignition angles and by introducing additional fresh air to the exhaust valves (secondary air system). Late ignition angles make sure that the exhaust gas from the cylinders has a higher temperature. This exhaust gas includes fuel that is un-burnt, and was deliberately injected into great quantities. The secondary air system adds fresh air to the exhaust gas as it leaves the cylinder and the extra fuel is burnt. As a result, the temperatures of the exhaust gas and of the catalyst increase quickly. The afterburning in the exhaust manifold before the catalyst changes the sound characteristic of the engine. This heating-up of the catalyst, including afterburning, is normal and has no effect on the service life of the engine. During this catalyst heating phase, the engine has increased idle speed, may have increased vibrations, and has a different sound characteristic. Depending on conditions, the time of the catalyst heating phase varies.
Update Bulletin2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. It is possible that leakage may occur at the weld seam on coolant expansion tanks manufactured within a specific period on Audi A8 vehicles. The Update is in effect until removed.
