are you sure that this is a 2.0 turbo engine? I am thinking a stock 2.0l or 1.8t or ???
posting the DTCs is a good idea so correct answers can be given. Did you use the correct spark plugs since that could cause problems. USE THE SAME AS WHAT THE DEALER USES!!! None of that aftermarket stuff that "fits"!
The 2.0l could have a bad ign coilpack AND they go bad. Test by misting with water while the engine is running. Or the spark plug wires. Or a vacuum leak.
The 1.8t could have wiring issues since I doubt that all coils are bad and then good again. Coolant Temperature sensor is a known problem too!
My mistake it is a 1.8 turbo
try a new fuel pump relay
Weeeelllllll.... unlikely............ BUT:
As this is on start-up, could be moisture in these coils causing the initial misfire condition. Is my dim-and-limited memory correct in that there was a bad run of these things at some point with hefty recalls or TSBs? I seem to remember this happening right around this year, even?
This would about cover the symptoms as on a cool, dry morning perhaps no problems, but a damp morning perhaps otherwise. And the running temperature would be hot enough to eliminate the problem after initial warm-up.
Just a random (mis)firing of neurons....

Well I don't see too many 1.8t engines with problems. I think I have had to change one ign coil on a 2004 Passat, but the other 7-8 that I work on have not had any of these types of problems. Well I did have to replace the ign module on an early 1999 (lost #2 spark).
I don't see the moisture affect these types of coils! BUT maybe so. ;-)
Coolant temperature sensor, MAF sensor, spark plugs or ???? OP should look here for more troubleshooting ideas
