I rotated to 6 and it was fine for the first 20 litres or so - but then returned its normal gentle pressure fill. Next time I am filling the car I will play with the flap (ow er missus) to see if there is a correlation. I was wondering whether being very low on fuel caused the vomitting back?
Ask to the dealer to check if the small tube (not the big one) is not clogged with fuel (number 12
