A little background here just to get things started.
I was driving back on the highway last Wednesday when I noticed that the 06 wrx was only hitting about 5psi of boost max. When I got home I did some test runs and it was happening in all gears. It would hit 5psi and hesitate to accelerate, no CELs or anything like that. I checked the boost lines and I checked the waste gate, both of those seemed fine as far as I could tell.
I took it into the local dealership today and they just called back. They said they found metal flakes in the turbo and that it is completely shot. Thankfully it will be replaced under the power train warranty, but they can't provide any feedback as to why it happened. Is this something that just happens, or is there a larger problem that is going unfixed? They only "mods" I've got are a boost gauge and a SPT intake otherwise I'm stock.
Thank for any help/insight.
