You won't get any codes using the key trick with a CRD.
I would put money on it being the turbo actuator.
When you turn the motor off can you here it cycle?
It possibly could be the swirl motor but I would think it would be stuck in limp mode if that was the case.
There is a bypass for the swirl you can try.
