    hi guys 1st post not a good start a4 cabby I got a P0252 code that started with total loss of boost and possibly fuel starvation. Wont rev up and very slow to get to speed. Just driving along the highway at 50 MPH and went to step down and no power, and the Ck Engine light was set and esp. Scan tool shows P0252 and erases but resets a minute later. Vac line look ok and starts fine. Any Ideas

    also when esp on lots of white /bley smoke clears when esp goes off and runs ok till back on even when eml is on

    Have you been on the Rosstech site and looked at the wiki to see what PO252 means?

    It might not help you if it's a generic code reader and not VAGcom.
