At 62000 car has finnally went into limp mode code PO299 been to dealer 3 times, last time dealer replaced turbo. On the test drive home I flogged it and it was a little slow to spool up and I only 10 lbs of boost it feels as if the waste gate opens up at about 10 lbs of boost and the car falls on its face any suggetions?

 

Well I'd try another dealer for the first step, sounds like they aren't getting to the root of the problem.

 

Stock??

 

Car is completely stock.

 

Did your plastic piece on the charge pipe break off or couplings come loose?
