You have a vacuum leak somewhere, or a bad PCV pressure regulator diaphragm.

How do you think he got the code he posted? You are trying way too hard to schlep your OBDGO on people here.

Yes scanned it via obd and cleared the " Light " but I get code P0174 " permanent " Its still Under Warranty as only a few months old. Letting Porsche handle it in a week or so. Just wondered if anyone has had this happen. Strange with such a new car .
