Typographical error on my part, it was supposed to be 201F - maybe 202F (best guess given the design of the gauge). And I've since sold the 3140 in favor of VCDS. But the results at 55 mph on two lane black top are the same; coolant temps moving back and forth between approx 194F and 201F, reflecting the actual opening and closing of the thermostat. And it's aggravating that there's absolutely no deflection of the cars temp gauge during these clear and consistent swings. It stays nailed about 1 full needle width above 200F.

But I've since found out that the thermostat that's supposed to be in there (059 121 111) is rated to open at 87C (~188F). Given that info, I'd expect the VCDS to reflect lower coolant temps. So now I'm a little less sure that the right thermostat IS actually in there. Car's in the shop right now, I'll find out what they have to say next week.

Ok there are quite a few threads talking about Engine Coolant Temperature (ECT) I found this ECT Checking thanks to MyAvocation.

That's just for the 4 cylinder engines in the regular VW line. And it's in response to an actual error code. My issue is with the 3.0 TDI six cylinder in a 2011 Touareg, no error code present. But thanks for trying.
