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?.

1440203383622022-08-01. Service bulletin. FUEL SYSTEM, DIESEL. Beginning with MY2009, the filler necks of various TDI clean diesel vehicles were equipped with a misfueling guard (Figure 1). The guard minimizes the likelihood that fuel other than ultra-low sulfur diesel will be put into the vehicle. The misfueling guard is designed to remain in a locked position when a nozzle with a diameter typically suited for non-diesel fuels (approximately 13/16?, or 20.6mm) is inserted, to prevent further insertion of the nozzle into the filler neck. A nozzle with a larger diameter typically suited for diesel fuel (approximately 15/16?, or 23.8mm) will unlock the misfueling guard when inserted, allowing the nozzle to be further inserted into the filler neck.
