I wouldnt be too concerned with the low coolant unless you monitor it and notice your loosing alot right away. small amounts of coolant loss is considered normal on turbocharged cars.
Did you remove the air filter and have a look? is the filter blocked or very dirty? Any signs of smoke from the back of the car while driving? White, blue, black smoke?
There is a small chance of a leaking injector - ive seen it on brand new vehicles..also leaking HPFP ive seen as well, mainly N20 engines tho.
Depending on how mechanically inclined you are, you could remove all the spark plugs or at least the first 2 or 3 and inspect them. See if they are covered in fuel or oil or full of carbon. My general rule for cleaning lightly worn spark plugs is soaking them in Carburetor cleaner and then using a small lighter or torch to burn the deposits off - i stay away from picks and small wire brushes personally.

Also take a look at the MAF..see if its dirty or has some dirt/debris on it as well.
