I've had a couple vacuum leaks. One of the most likely is the oil fill tube, either where the 2 sections couple together near the throttle body, or in the accordian section near the rear bulkhead.
The best way to pinpoint the source is to take it to a shop/garage that has a smoke testing maching. It slightly pressurizes the intake system with some non-toxic smoke. The mechanic found I had a leak on my brake booster line.
If you have a Tiptronic the coolant control valve can make a vacuum leak. There are a bunch of places. That's why the smoke test is so good. The foreign car garage I went to only charged me $75 to do the test.
