So recently my girl friends parents TT quattro threw a P2015, P0171 (irrelevant I think). P0304, 303 (also irrelevant). The P03 codes are for misfires and the P0171 says fuel line. The P2015 code relates to the IMAU (intake manifold adjusting unit). However on ecstuning they say this is for a FSI not a TFSI. What does the T mean? Turbo? Anyways I looked at the part that seems similar but it is part number, 06F 133 062J. That is for the intake manifold which is considerably more expensive. Does this previously listed part number throw the same code as this part, http://www.ecstuning.com/Search/06F_133_482e/ES281203 ?

I am going to clear the codes next and attempt to force throw the code by unplugging the intake manifold flapper. But either way if anyone has had this problem let me know what ya'll think. Thanks.

after further inspection of the engine it appears there is a vacuum line that is not connected to anything. It is instead connected to an actuator that appears to open or close the valve variably (dependent on some factor i do not know). If i put my finger over the vacuum hole the engine runs fine no rough idle. Problem is figuring out exactly where it goes?

The tip of my finger shows the vacuum hole. In front of that is some kind of actuator. No idea where thats supposed to go. But I could be wrong, but as an engineering student who enjoys cars, it does not make sense to draw unfiltered air into the engine. This has to go somewhere?

I dont know what that is called but if i figure that out i can get a diagram showing the line routings.

thanks!
