ANY DEBRIS THAT WE SAW WAS STUCK IN THE SUMP SCREEN, NO BOOST AT ALL,TURBO MAKING NOISE LIKE ITS OPERATING SLOWLY

VW Mechanic: Cardoctor74, ASE Certified Technician replied 7 years ago
Ok you need to remove all lines to the turbo check the waste gate and vacuum lines . Sounds like there is debris or sludge that got up to the turbo . Hopefully the turbo was not damaged . It's possible it did get damaged . I would see if there is anything causing any blockage to the turbo next.

Even if that diaphragm looks good it might not be holding vacuum did you perform a vacuum test to the valve .'

No engine light at all ? And the boost valve is good and not abnormal noise from the turbo ?

Customer reply replied 7 years ago
YES ON A EARLIER TEST DRIVE I GOT A P0299, AND THE NOISE FROM THE TURBO IS LIKE A TINNY VIBRATION
VW Mechanic: Cardoctor74, ASE Certified Technician replied 7 years ago
Ok that code is for that valve has to be malfunctioning or there is an internal issue with the turbo if it's making noise then the problem lies there.
