If it really is a sticking wastegate then it really is a matter of rebuilding the turbo. $800 or $900 seems a little high to me - a rebuilt turbo shouldn't be more than $250, and fitting it is only 2-3 hours. But it's quite unusual to have a sticking wastegate. Is your mechanic absolutely certain that that is what's hapening? Your symptoms are consistent with a sticking wastegate, but they could also be caused by a whole load of other things. -- Grunff
