Re: A4 18t engine
could be a number of things. fuel pump could be one. I don't know how they are set up on that sort of car. Or, again like somone has already said (sorry didn't catch the name on the post)could be an air lock. to be fiar tho, inless you know what your are doing (in witch case you would have a pretty good idea what is wrong with it) I'd take your motor to a local garage and ask them for there opiniun after they have seen what is happening. They may know strate away, or at least point you in the right direction.
