Any car, doesn't matter as the valves will operate the same. There is no time on any car, UK or otherwise, that the valves are 100% open unless done so via VCDS, period end of story.

Parked as in car off?

Yes that is how they work. With no input, they default to open - so if you unplug the sensors to the flaps they will always be open. As soon as you start the car they close.

If you disable the flaps in VCDS you will clearly hear/feel the difference...

Gotcha. No plans on doing that. I purchased the vwr with the valves so I can keep the stock feeling.

Old thread I know but thought I'd throw in some information to confuse things even more.
Note that i own a de-tuned R so mine might be suffering from a problem (that the dealer calls a feature) where the flaps don't really close as they should (I have a permanent non-reversible flapper mod from the factory so why I even have flaps is beyond me!).
In an effort to check that I first tried to disable the flaps via VCDS for a day (unchecked the "installed" bit) - felt no difference but that was expected.
I know I HAVE flaps and they ARE connected and they show up as functioning via VCDS but it seems that they just stay open no matter what.
I started measurements and looked at those 3 measurements pictured doing all sorts of driving styles you can think of at all modes of drive (comfort, normal, race, eco, individual).
Switching on the car (ACC on, Engine off) I get this:
Engine on:
And this stays as-is no matter how the car is driven, no matter what the speed is, cruising, WOT, letting off gas at high or low speeds. Even at coasting in Eco mode those values stay as they are: flaps open and 90.002%, 90.00%.
Now I sort of expected this given that I'm losing my hearing after driving the car for 2.5 years but i was wondering if anyone with a "proper" car that closes the flaps as well as VCDS can do the same tests and see what values they get?
I forgot to test the flaps in VCDS which I will do later. Maybe if the close test works then I unhook the wires and do a reverse-flapper-mod!
EDIT: nevermind, seems someone did the same thing and got to the same result here (http://www.vwroc.com/forums/topic/4337-exhaust-valves-someone-with-vcds-please-help/) - back to the dealer I guess.

The flaps are open when in race mode, i would code it and have them open all the time!
See my sig. And you don't want to code them always open.
