Or a P2580 which is low turbine speed sensor. THis can also indicate the turbine is not spinning fast enough. The reason you would want them to warranty it out, is because the new updated turbo has a whole new casting. Works much better and spools quicker. You will like it and the good part, is you don't have a whole drilled in your turbo.
I have a theory on why they clean it instead of pulling it and replacing it. When you drop the turbo, it hits the motormount before it clears the studs from the exhaust manifold. Pain in the you know what to remove and reinstall. If you are within warranty, just make them change it out for you. especially since you have had it cleaned once and it didn't work.
Oh and hopefully they didn't reflash the computer. The do that with out permission and the newer flashes are not always good.
Good luck, and let us know what happens.
