Have someone handy to press the gas pedal for you after the engine has warmed up well; best if driven.

While you listen at the exhaust pipe, have your helper increase the revs slowly and note whether the exhaust note changes to a hiss, instead of the sound of an engine firing.

You may have a decayed catalytic convertor and when they come apart inside, they can clog mufflers and resonators (the second, smaller muffler).

I've had this happen on more than one car and when it happened on a Fiat Strada years ago, since the routing of the system was fairly straight and made of heavier gauge stainless steel, I fired two shots with a .357 magnum into the tailpipe.
Never had another problem with it.

you could check the fuel pump i recently had some problems with my punp after i replaced it where i would get to 3k rpms and it would sorta shut down and wouldnt go past it untill i let off the pedal

these cars are fitted with a fly by wire accelerator pedal that is controlled electronically by the cars computer it is possible that there is a computer problem or the throttle body ( air intake system )or accelerator pedal is playing up.
it is highly possible that the car is doing exactly what you say it is i recommend you take it back to VW and demand that they take a proper look at it you might have to leve it with them for a couple of days and get a service advisor to drive it home so as they can see the problem ocure.
regardles the cars computer should of thrown a code declaring a fault in the system witch should give the tecs some were to start looking.

good luck with this problem if you have any outher questions let me no

The evaporation canister can cause this, so would any vacuum leak. A faulty throttle position sensor or camshaft position sensor would also cause this but it would in the diagnostics most likely.

I have same problem with 2002 laguna. Before warning lights and revving at 2000rpm starts car feels jumpy. Have to stop, take card out of slot and back again to start without fault. Happens a few miles drive later again. Anyone got a solution?
