What buffles me is,that if it is a matter of defoaming agent,shouldnt the problem occur when the tank is almost full?I had this problem with the tank almost empty and both times the station's pump was stopping almost immediately...

Hello there and thank you in advance for any help given. I just bought a used Octavia Scout 2015 2.0 TDI 150 PS and i have a strange issue...I tried filling up the tank at two gas stations and it was impossible without the gas-station's fuel pump stopping almost every second,like the tank was full. The tank was almost empty especially the second time i tried refuelling. It took about 20 mins to fill 40 ltrs of fuel... Since the car i bought was imported from France to Greece,is there a chance that the fuel tank's opening is not suitable for the Gas-stations' pumps here? Is there a relief valve malfunctioning and therefore fumes pressure builds up and not letting the pump work? Thank you all
