Service bulletin Dealer Letter -
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.

NHTSA's summary
This communication is to inform you of upcoming Update 20W8. On Audi A8 vehicles with W12 engine manufactured within a specific period, it is possible that the fuel tank breather line leading to the activated charcoal filter may have been damaged by the use of an unsuitable spring-type clip. The fuel tank breather system may develop a leak as result. Replace t-piece connector and clamps.

| 01146220361693 | 2023-01-03. Service bulletin. 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?. |
