Coilpacks: What make the spark plug spark in a 1.8T. These have been known to have hairline cracks form, which cause the spark plugs to cease firing.

MAF: Mass air flow sensor, which tells the on board computer how much fuel to push through the fuel injectors. If this is bad, the computer isn't sure how much fuel to push, and could kill it.

I'm not the best at diagnosing the 1.8T stuff, but I don't think it's either of those. My guess is the Immobilizer Chip, which tells the computer that you have a valid key.
