My Audi A4 was parked for a while and now when I try to start it with push start button, it cranks the engine for a while but doesn't start the engine. Then it tries to start again 2 more times, then nothing. What could be wrong?

Most likely a fuel supply issue. Check fuel pump. The fuel pump is responsible for delivering fuel from the gas tank to the engine. A failing fuel pump can cause a weak or no fuel supply and result in no start. You can check the fuel pressure at the fuel rail to determine if the fuel pump is working correctly.
Could also be fuel pressure regulator. The fuel pressure regulator controls the fuel pressure in the fuel system. A faulty fuel pressure regulator can cause a variety of issues, including starting and performance problems.
