Check first for leaks in the resonator and intake hose plumbing.
When boost is lost due to leaks, the ECU (hence the error codes) can be a bit confused.

According to Andy in this thread, P2359 is specifically "low boost"

and, again, here: (remember that a leak can be *hard* to find)

Even the intercooler itself can crack.
