Strange Occurrence this Morning, Could Use Some Help

Ok, so this morning I go to start up my car and it stalls out. I'm thinking maybe I didn't give the fuel pump enough time to prime or whatever; this used to happen once in a while on my old silver GTI if it was cold and I just jumped in and tried starting it real quick.

So I let the key sit in the ACC spot for about 5-10 seconds before trying to start it again. This time the engine sounded like it was trying to turn over but it wouldn't catch. Tried again, still wouldn't catch.

So now I'm very confused. Last night I emptied out my catch can, so I pop the hood and check all the fittings; everything was attached fine, no problems there. I tried starting the car again and it starts up this time. Except it's very rough. The RPM's weren't varying or anything, like others have noticed during a rough idle, the car was just shaking. So I turn it off and am even more confused than before. Next time I started it up, turned over just fine, idled fine, and I was off on my way. No other problems for the rest of the day.

Anyone have any insight as to what happened? Should I be worried?

Sounds like a low fuel pressure problem (either on the low pressure side or the high pressure side). You should run vag-com and check for codes.

i've had some pretty rough cold starts and the occasional 5 sec crank starts. Never have thrown any codes for it. I have basically come to the conclusion that direct injection doesn't like cold starts (or cold starts and then turning it off quickly after that).

I think I still get misfires on cold start after replacing coilpacks and sparkplugs.
That's since I seafoam'd my car.
I leave the key in ACC position for 5 sec for 3 times but sometimes I still don't get clean start up.
I F'in hate it.

Sometimes mine starts right up. Sometimes it doesn't. It's the most tempermental, inconsistent car I ever had.

:word: this morning I unlock the car with my fob got in and no electrical.... WTF hit unlock again while sitting in the car as all is normal again.

x2. op, how many miles? i wouldnt think that you would have too many, being that its an '08 but maybe its time to change the fuel filter.

about 24,500. Been stage 1 for about 15,000 and just changed the cam follower this afternoon. Luckily, I havnt had any other problems, hoping it was just a one time thing,

Exact same thing happened to me yesterday. 25k miles, changed fuel filter 6k ago. Maybe spark plugs/coilpacks need changing? Or fuel pump?! Just got out of the warranty 2 weeks ago!
