I wish I could say otherwise, but yeah it does seem that way. Sucks, because the NMS is a decent, albeit boring, sedan. Drives nice, roomy, has a nice conservative non-flashy understated styling that doesn't seem dated, and in the case of the TDI, an engine that can absolutely trounce the non-hybrid competition for fuel economy. Plus, they were offered with a proper manual gearbox to boot, even though Dieselgate caused a lot of the 2012-14 diesels to needlessly be crushed. But if the company that designed, built, and marketed it have no interest in properly supporting it, then it quickly becomes a nuisance.
I was an outspoken champion of Volkswagen, and was one of their biggest fans. But this whole Dieselgate thing, which I don't entirely blame on them but more as an overall steaming turd of a draconian legislative nonsense that forced their chicanery in the first place, has soured me. It has not just soured me on Volkswagen, but soured me on the absurdity of the idiots fighting so hard to try and make a square peg fit in a round hole, when the round peg not only fits better, but generally works better and is more efficient in the first place. But hey, they'd rather us buy a bunch of pump-sucking square pegs and then try and force something unobtainably expensive and unrealistic on the consumer. It's just dumb. Dumb, dumb, all around dumb.
So, as an act of defiance, I will do my very best to keep the older TDIs on the road for as long as I can, and as many as I can.
