What would cause a P2293 code on an 06 VW Jetta GLI.

I just bought a 2006 Volkswagen Jetta GLI 4 cyl 6 spd manual turbocharged used, and it has two indicator lights on the dash. The first one is letting me know one of the fog lights is faulty. The second one is a check engine light. There is a place here where I live that specializes on VWs and imports. I went there and they wanted over $60 just to hook an OBD II scanner up to read the code. I decided I would go to O'Reilly's and do it for free. The code that I recieved was a P2293 "Fuel Pressure Regulator 2 Performance"

The vehicle is in great shape. Shifts good, and runs good, but I notice a slight rough idle when you are just sitting still. You really have to be paying attention to notice it. The fuel efficiency isn't as good as it should be either, so I know something is up. I have been trying to track down what exactly this could be but when I gave the code to the service tech at O'Reilly's she printed off a page on the code and it gave no probable causes. It just gave possible fixes for it. As much as I would like to do everything from changing the cam shaft to fuel filter and various sensors on this car (Cough "not really" cough), I find it hard to believe that with how popular these cars are, VW and all the technicians dedicated to them and imports have not found the exact reason why this code is being tripped and what can be done to fix the problem.

I have been doing some exhaustive research but many of these forums people post their question simple with no details, and that leaves the experts (you guys) giving an equal answer and that doesn't help me out very much.

My car starts and drives fine. As I said when you're sitting still you can notice a vibration/rough idle. The car has been well maintained. It was previously owned by a middle aged person and they took good care of it mechanically and visually.

I would appreciate any information anyone can give me in getting this fixed. I would love to be getting the full fuel efficiency this thing has to offer, and I would like for my first VW to not be my last. The car is a great one!

Please feel free to e-mail me for any other details such as VIN or anything else you may need. I don't feel comfortable posting it in the open.

Thanks for your time,

Chris
