I have a Audi A4 1.8 t 2005 and every time I refuel the car it take a few cranks to start... I have change the fuel filter already.. Any I deas.????

 

I am guessing here. It sounds like the fuel pump might be getting a touch weak. When you open the gas cap you release the preasure in the system and when you restart the car it needs to build back up. Usually the fuel pump kicks on and primes the system. If the pump is getting weak it might cause this. I am surprised you don't have the same issue after the car has been parked awhile. Might try removing the gas cap and then putting it back on and see if you get the same issue.
