A TSB is a Technical Service Bulletin.

Update: I have gotten the PCV, the intake motor regulator actuator, and the low pressure sensor replaced by the dealer all for free. It did fix the problem with the two codes I was originally getting. Unfortunately, 2 days later, I had the CEL come on again! This time it is throwing a P0089 code. Anyone know what this might be? Thanks! : )

Yes. I do have the 2.0T and I definitely am getting the P0089 code.

I just checked both of my online repair info sources and it only lists that code for the 3.2L engine. Its for the low fuel pressure sensor.

Again.I definitely have the 2.0T and I definitely have he CEL light with the code P0089 on it reading "Fuel Pressure Regulator - Performance" VERBATIM. I used three (3) different OBDII scanners to make sure that was the code I was getting because of what you said about it not being for this engine. I have also checked many different audi forum sites and there have been many others WITH my same car and engine that have gotten this code before as well. I don't know what your sources are but theres gotta be someone out there that knows what is happening here. This site has been an awesome resource for me so far, and I'm not trying to shoot you down or offend you, but Im really just trying to figure out whats going on.

Here is some feed back I have gotten so far.
Could be a problem with the low pressure sensor (possible dealer warranty item I believe). Also if wrong oil is used, the cam & follower that activate the high pressure fuel pump on the head can wear out. Worst case will need a camshaft, cam follower & pump.
