if(radio.available())
{
radio.read(&text,sizeof(text));
Serial.print(" ");
Serial.println(text);    
}
else
{
Serial.print("Fehler");
}

That is a bad idea.
99.999999% of the time there will be no packet available,
combined with the 9600 baud, it will nearly halt your sketch blocking on Serial.

The 3.3V of a normal Mega is not sufficient for a NRF24L01+, I second that.
Making pin 53 an output, could help the SPI library play its master role.
