It's not CPO.
Car had ~82.25k miles on it when I bought it. Engine malfunction light (30FF - low boost pressure) light came on at ~82.50k miles. Took it to the dealer, dealer says turbos are blown.
I'm not sure if the turbos blew right after I bought it or if I got the car with blown turbos and I just didn't trip the indicator until 82.5k miles. Either way, it's looking like a new set of turbos for me paid out of pocket.
