My wife drove the car (Audi Q7 2007 TDI) until it
finishes all fuel. Now the car is not starting.

The pump seems to be working fine. According to
the person who normal assist the car, it has air

causes and how can it be fixed?

Open the hood of your vehicle and locate the fuel rail. This is normally located towards the back of the engine bay, on top of the engine towards the firewall. Locate the Schraeder valve. This valve looks like a valve stem that you would normally find on a tire. This valve is a bleeder valve that will release pressure and purge air from the system if you loosen or remove it. On some vehicles, you may be able to press down on the valve to release pressure. Place a rag over the end of the valve, and either loosen the valve with the wrench or depress the center of the valve with the flat head screwdriver. You will hear air coming out of the valve, but you may also notice gasoline spraying out also. The rag is to prevent the gasoline from spraying all over the engine bay.
