I am dealing with the same problem, and mine is due to a slight miss at
all speeds, idle to whatever.  This is generally caused by a lean
mixture if the engine and ignition system are in good condition, which
mine are.  Check your plugs, cap, rotor, and wires first.  If they are
okay look for a vacuum leak and then move on to the fuel injection
system.

You can hear or feel the miss if this is your problem.  You can throw
parts at it like I am (I have lots of spares) or take it in to a good VW
shop, but expect to shell out some bucks either way.

As of today I have not fixed it.  I am down to injectors or fuel
pressure regulator as the culprit, neither of which I have checked yet.

Have fun!
