djug.....,

I would leave it the way it is until the turbo is destroyed. That way you will get a new turbo for sure at no cost.

The dealer might say the turbo is OK and if it breaks after the trap oxidizer is replaced, you will be stuck for the cost of replacing the turbo.

Or least ask the dealer if they will replace the turbo. If not, try another dealer. If none of them will replace the turbo, go back to paragraph one.
