Does anyone know why some gas stations have oversized diesel nozzles that do not fit in a VW TDI, while others have correct size nozzles? Conoco has the right size, Shell and BP do not. I have found this situation in multiple states. ---

Because those pumps are for good hardworking trucks filling up several hundred gallon tanks, not the few-dozen “litre” tank your little foo-foo Euro-mobile. Plus even if the nozzle was the right size, those things pump way faster than an auto diesel pump so it might very well make a mess fueling up your TDI with them. Sometimes if you poke around, the stations might have one auto diesel pump hidden somewhere. ---

Maybe the filler nozzles that don’t fit also don’t dispense the proper low-sulfur fuel. Just a guess, but it’s something to look into. I thought all diesel fuel sold for on-road ( large trucks or diesel cars like yours) use had to meet the same federal requirements, but I’m not a diesel driver so I could be wrong.
