Short answer: you can't

It's virtually impossible unless you have teams of lawyers and millions of dollars to spend, and even then it will be registered as "Show and Display" at best, and illegal to drive as a daily driver.

You can still buy a ton of sporty SUVs on the same platform as the Touareg legally in the USA: Q7, Cayenne, Bentayga, Urus.

Thank you very much for the information. I know the Cayenne is the closest, but I was looking for the TDI engine, which is not available in the US.

That's a whole different can of worms, I'm sure you've heard of the dieselgate scandal? Importing a post-dieselgate VW diesel to the USA will be even more impossible than a gas one. They were banned for a reason, and made an example of... you might as well be asking how to import cocaine from Colombia.

If you have the money for a vehicle that new, consider one of the few unsold "brand new" 2016 TDI Touaregs still on the market. There are two that have been on AutoTrader for a while for about $50k.

NOx emissions in dense urban areas kill a lot of people,and massively lower the general quality of life in those areas, and diesels are responsible for most of it, so the issue itself isn't BS. However, the standards were probably increased too quickly and basically exceeded what was technically possible at the time, so the "honest" companies pulled diesels from the market, and the rest cheated- nowadays it's come out that basically all of the diesels on the market were cheating at the time.

It's especially a shame because, now that renewable diesel is widespread, diesels can actually have a lower carbon footprint, and less environmental impacts than even electric cars, but the ability for people to get diesel passenger cars nowadays has basically been lost.

You don't have NOx emmision because these TDI cars have AdBlue (BlueMotion) system. Urea solution is injected into exhaust and all NOx gases are neutralised

This isn't correct- AdBlue systems reduce NOx a lot, but don't totally eliminate it. The issue with the dieselgate scandal on the 3.0 TDIs was basically that they weren't injecting enough AdBlue for the system to actually work effectively. Post-fix they now inject enough but with the consequences of running out of AdBlue quickly, and wearing out parts in the system frequently.

California (one of the filthiest, polluted states)

I'm always amused that people think Californian's in particular will care when people insult the entire massive state. Fun fact- the geography in SoCal and the central valley (both places I don't live anywhere near) makes the air famously polluted since long before Europeans even arrived or explored these areas. The Native Americans had major air pollution issues in those places because the bowl shape and poor air exchange combined with a dry climate and high fire risk makes them naturally almost uninhabitable places due to poor air quality. Now throw in some of the biggest cities in the world with tons of combustion engines and you'll have some crazy bad air!

In the 1500s when the first spanish explorers arrived on the coast near LA, they dubbed it "Baya de los Fumos" or Bay of Smoke because the air quality was so poor.

Don't believe everything the left tries to force feed you.

This explains why your arguments about emissions, etc. are incoherent and angry, without any kind of clear perspective or point, and you stick to them even when you find evidence yourself that they're nonsense. You are thinking about this as a polarized political issue that you're angry and one-sided about, instead of actually understanding and thinking for yourself. Anyone who thinks the "left" or "right" understand a damn thing about physics, chemistry, health, ecology, etc. is totally disconnected from reality. The world - reality - is too nuanced and complex for any political ideology to say anything useful about it.

The funny thing is if anyone has an actual nuanced or informed opinion on any topic that they've developed from studying the issue themselves- nowadays most people from "all political sides" will instantly label them as "propagandists for the other side" because those people can't understand that deep technical rather than political understanding even exists, or how much actual work/study is required to get it.

I'm vaguely familiar with the procedure for importing a "gray market" car for personal use, or at least the way it was done in the past.

A car has to be at least 25 years old to be eligible for grey market import
