11 JSW, turbo failed then engine died on me

[DoubleAsterisk]

Yesterday I was driving on the highway, everything was normal till I stopped at a rest area, I left the car for 2 minutes and when I started the car up again and accelerated I heard a loud high pitched whine (exactly like this) and the lack of power. I lost more and more power and the flashing glowplug/CEL came on, i pulled over on the shoulder and waited a bit, restarted and the light didn't come back, scan tool showed P0299 turbo underboost. After limping it on local streets for about 10 minutes trying to make it to the dealership the car died on me and i had to get it towed.

I'm praying this will all fall under the extended warranty, I'm sure the turbo should be covered but I'm worried I caused damage further down the line, anyone know what killed the engine?

So, until you get the full diagnosis, all we can do is speculate as to what might be the cause. The underboost condition could be cause by lots of things, unfortunately. Could be EGR/dpf issues, could be you ran the car out of oil somehow, could be something silly like a sensor, but as much as I hate to say it, with the whine you described I'm forced to lean heavily towards "sudden no oil condition"

Sounds like the turbo died, you didn't shut it off, and now it needs an engine.

Im going to say the impeller broke, and pieces went into the intake and the engine.
