Service bulletins for the 2013 Audi A8

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.

011469203666812023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. When diagnosing the condition listed above on a common rail diesel vehicle, if no root cause is found after all GFF diagnostic procedures have been performed, it may be necessary to check for metallic particles in the high pressure fuel pump using the procedure in the Service section of this bulletin.
011462203616932023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. In tank, fuel pump may be making a straining noise. Diesel fuel requires additive blending or ?winterization? to be useable at low temperatures. At temperatures below 20° F (-7° C), No. 2 Diesel with insufficient winterization blending may lose its fluidity due to wax separation. This may clog the fuel filter or in-tank filter, preventing the engine from operating properly. No. 2 Diesel is blended by refineries to various levels of winterization (minimum useable temperature) based on month, geographical location, and the 10th percentile minimum ambient air temperature for the given region. Although rare, during sudden periods of extreme low temperatures (record lows), fuel stations may not be adequately prepared with No. 2 Diesel fuel with sufficient winterization to resist wax formation or ?gelling?.
011461203523522023-01-03. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. The fuel metering valve of the high-pressure fuel pump is controlled by a specific on/off ratio. If there is a low system voltage, the on/off ratio may not be enough to keep the fuel metering valve constant in all areas. In such a situation, the fuel metering valve is deactivated and the high-pressure fuel pump switches to full supply mode. Because the increased rail pressure does not match the respective driving situation, the DTC appears.
011459203616922023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. In tank, fuel pump may be making a straining noise. Diesel fuel requires additive blending or ?winterization? to be useable at low temperatures. At temperatures below 20° F (-7° C), No. 2 Diesel with insufficient winterization blending may lose its fluidity due to wax separation.

011375203322412023-01-03. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, DIESEL. If an Audi model year 2014 A8L TDI clean diesel (engine code CPNA) 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.
011336203523512023-01-03. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. fuel rail pressure too high; noises from engine compartment
001466203794912023-01-03. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). A DTC with the description ?Invalid Data Record? is stored after an ECU has been replaced or updated.
001464203558122023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. 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.
001463203357622023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. 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.
001459202973722023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. When oil is drained through the drain plug, the oil might spill on components around the oil pan area. If it is not properly cleaned up, this spilled oil could drip after the procedure is complete, causing unnecessary customer complaints.
001351203185042023-01-03. Service bulletin. PARKING BRAKE; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM.
