Aight, so i've been driving my fd for a few days now, and i noticed a couple of problems. First off, when I drive the car for a few minutes, then turn it off, and try to restart it again, the car wont start, i gotta wait for a few minutes so it cools down. Another prob is when i drive for a rather long time, for example the other day i stopped my car and there was some liquid that was literaly boiling under the hood...i was guessing prestone, but im really not sure. Then another prob that im concerned with, is my turbos. My car is TT, and i dont get any boost at all before 4500rpm, and if im not mistaken, i tought TT were getting boost around 2600 rpm. If someone can help me figure out my problems it would be appreciated!

 

My suggestions:

Problem 1: Car not restarting while hot. Check the Fuel Pressure Regulator solenoid and it's associated lines. It deals with "hot starts" to help with vapor lock.

Problem 2: Start with doing a coolant flush and replacing the coolant caps (coolant filler neck cap and the AST cap).

Problem 3: Use the following guide for troubleshooting stock turbo problems:

Here's an overview of how the system works:

By using the overview, you can narrow down the components which are active before 4500 rpms.
