I think you have 2 different issues. The P0299 is an underboost. So either you have a significant boost leak (my inlet manifold was split along the bottom seam) or the turbo is not making boost/wastegate stuck open.
The P16/17 seem to be related to the crank vs cam position sensors do not agree. Now it could be wiring, I think thos circuits share the same circuit somehow.. You'd need to check the wiring schematic to be sure. Of course it could be one of the sensors.
I can't think off hand why all three codes would relate to the same problem. Did the codes show up at the same time?
