What happened to the small airflow in the intake system of Audi q5 p227900?

It shows that there is a leak in the air intake system and the crankcase pressure regulating valve may be broken.

Definition of Audi Q5 air intake system: The air intake system consists of air filter, air flowmeter, intake pressure sensor, throttle body, additional air valve, idle speed control valve, resonant cavity, power room and intake manifold.

Working principle of Audi Q5 air intake system: When the engine is working, the driver controls the throttle opening through the accelerator pedal, changes the air intake and controls the engine operation. After the air entering the engine is filtered by the air cleaner to remove impurities such as dust, it flows through the air flowmeter, enters the power room along the throttle passage, and is distributed to each cylinder through the intake manifold; When the engine is idling, some air bypasses the throttle and enters the cylinder through the additional air valve or idling control valve.
