If there are no leaks, the only other that I believe could set this code is a pressure sensor. The charge air pressure sensor can be tested. I will provide the directions and steps. If you feel comfortable doing it, great. If not, let me know.

Charge Air Pressure Sensor (G31), Checking
The Charge Air Pressure Sensor (G31) is located in the inlet to the intake manifold. The Engine Control Module (J623) uses the sensor's signal to regulate the charge air pressure. There is no substitute function in the event of signal failure. Charge air pressure regulation is shut off, leading to a significant reduction in engine output.
Special tools, testers and auxiliary items required
