That coil and most of the newer VW/Audi coils (the exception being the Audi AEB engine code circa 1998) does indeed have an internal ignitor (transistor).
The Ground is terminal #4 not terminal #1 according to the HUEGO diagram.
What is the Ignition Driver Configuration of your ECU? (8,4+4,2+6)?
What drivers or pin numbers are you using?
I do not know the dwell of that exact coil but with the others I have used it takes almost nothing to get the engine to start and idle. I have ran the VW/Audi 1.8t coils down to almost .5 msec at idle before noticing a difference, I use 2.9 msec for my normal setting.
And the coil on my 1993 VW Passat VR6 (distributor model) runs at 4.8 msec at idle.
I think your problem lies elsewhere.
