Fuel Pressure Sensor. 2006 Audi A4 quattro
 

Greetings everyone,

So my gas levels keep doing up and down randomly, I'm guessing my fuel pressure sensor needs to be replaced, however I can't really locate it. I've looked into some models but its nowhere near the engine. Would appreciate some help. My car is 2006 Audi A4 quattro cabriolet.
