Well, I got my car back on the road (luckily it was just a coilpack.) Yesterday I was sitting in my driveway with the car running while I played with my vag-com. After about 5-10 minutes of idling in my driveway (this is after a short, 2 minute, drive up the street and back) I could hear a "gurgling" coming from the car. It was my coolant resovoir spewing water out the bottom.

What's weird is that my guage never moved from its normal spot right in the middle. I checked my coolant flange and it's still sealed.

You guys have any ideas as to what this might be?

ps. I plan on flushing the coolant this weekend if I have time.
