I am looking for a vnt assembly from a gt1749va for my 2005 Passat. I need the piece with the vanes from inside the turbo. After months of trying to diagnose my limp mode/underboost issue it turned out to be a messed up vnt vane from an improperly assembled turbo from the previous owner. Any idea where I can get one? I have seen some Chinese made ones on ebay but would prefer something from a reputable company or a used one. Thanks!
