I have a 1997 talon tsi that wont pass emissions. the dmv computer says that there is a trouble code on but nothing comes up. a guy i know showed me that the egr system was not hooked up. is that the cause?
Very well could be, if it will not pass due to a trouble code. If it is the actual emmissions that are tested and then failed due to the CO2 emmisions then it could be a myriad of problems.

I would try making sure spark plug wires are put on in the correct firing order. This is a common mistake in tune ups. Most intake manifolds have the firinging order cast in. Plug gaps correct? I cant come too far away.
Possible bad starter , low voltage in battery meaning dead battery or just bad and corroded connections at battery post and starter. Try cleaning connections and recharge battery if needed.
Te 1st thing to do is replace the oil pressure guage sending unit, most times that is the problem, if press remains low use a mechanical test guage to verify what the oil pressure is, hook this tester up at the port the sending unit is screwed into.
If it was originally intended for Texas, it's probably been made as a 49-state-compliant vehicle (CA has stricter emissions). To pass in CA, you may need some new parts for the truck in order to get it to pass. Or you may find that the best course of action is to sell the truck and buy a CA-emissions car.
The CA DMV may well have information available on how to get non-CA-compliant cars to pass the CA emissions testing.
