Not that that takes away anything else from what you wrote... But it's unlikely to be a simple thermostat
Again, not familiar with the specifics of this engine or the apr tune, but none of this is outside the realm of possibility...
But I'm just here for the party
The thermostat is only a spring?????
What happened to the wax which.... is expanding against the spring force... that actually opens the thermostat... The spring only closes it.
Turn of Events
They can't find a coolant leak after "extensive" testing.
I had a coolant warning in ~July. I added some Audi-OEM coolant and 50% distilled water to the "medium" tick mark level.
Now I'm getting the coolant warning again in October after driving about 800 miles per month and the coolant is slightly below the minimum level.
I have heard that these engines all burn a little bit of coolant. But this seems excessive. They want to let the vehicle settle over night.
Maybe the head gasket is shot? If so, that's a pay out of pocket repair. I will give you that.
With your car on a lift, they can remover the plastic engine splash shield, and see 'deposits' below the waterpump if it is leaking.
IMO, it's just the dealer saying 'we don't see a problem' and hoping you go away.
Edit: Since January 2016 and about 50,000 miles.

Incompetent dealer, take it to another store.
Sorry to say but you will be suing and probably losing unfortunately.
Zero coolant loss in 50k miles and counting on my gen 1 EA888.
They don't want to deal with you fighting them on the repair since you already told them they can't void the warranty, so they are washing their hands of you so you go away before it even starts.
welcome to the layer cake
I've owned four EA888s between 2007 and 2018. With the exception of the Gen 3 (currently own, although not for long at this point), the other three (two Gen 1s and one Gen 2) all lost small amounts of coolant during normal operation. Had one water pump fail on the 2007, but aside from that, there was some amount of small regular consumption. It bugged me.
OP, how much coolant have you been losing? It sure sounds like it's more than the small amount I'm describing, but my anecdotal evidence points to these engines consuming a bit of coolant regularly.
Google the *same* problem for MK7 GTIs.
The 2.0T loses coolant from a weep hole in the t-stat housing and leaks down the side of the block. Often unseeable. Often because the water pump is leaking. The only coolant they're burning is what's being burnt off after leaking onto the block.
Source: Same thing is happening with my car.
Pretty sure the same thing happened with the MK6 2.0T FSI as well.
There's tons of threads on the Golf M*K*7 boards about the issue.

I think with the dealer already playing dumb, it is a clear sign that the rodeo has begun.
Maybe I missed something, but I don't recall any indication that Schnell has said anything to Audi or the dealership about lawsuit, M-M act, or being a lawyer. Last I saw he was going through the normal motions that any customer would and is paying the diagnostic fee to see what's wrong.
The other aspect of this that (I think) is lost on a few of you is that I've been totally open and honest with them about the car. I didn't try to put it back to stock or anything. So we'll see. It's also possible that the coolant level sensor itself is faulty (although that wouldn't really explain why the coolant level visually seems to have gone down over the past couple months).
So who knows. If they say that they can't find anything wrong with the car, I will probably bring it to an indy mechanic for a second opinion. But as I keeps saying, let's see how this plays out.
