This statement is NOT
correct. The turbo is a mechanical device that cannot be turned off on its own, separately. If the car could be driven to the dealership, then nothing was shut off - not the engine, not the turbo. The turbo's operation is dependent on the engine's hot exhaust. If the engine works, the turbo does. And if the turbo fails, the engine fails in the next 10 seconds, having sucked all the debris (if the blades get destroyed) or the engine will feel massively underpowered, if it is a turbo oil leak/coolant leak issue.
I also doubt the CEL (Check Engine Light) for the O2 sensor - but then again, on Subaru, people's experience with O2 sensors falls into 2 categories: those that always have problems and those that drive 200,000 miles on the same O2 sensor, beating the crap out of the car and modding the engine to within 100 rpm of its death, and then get rid of the car, with a perfectly functioning O2 sensor inside.
I've driven my modded Subaru at high altitudes and never had an issue. There's nothing but joy driving it, knowing that most everybody else's non-forced induction engine is astmathic. I mean, that's when the guy with his 6.4 L V8 Corvette gets owned by a turbo 2.5 H4 (modded, I admit).
