my S1 is still playing up.

as soon as the temperature goes up the fuel pressure drops and the car stalls.

just collected from the garage but they had a look at the some sensors but want the car back next week to look again.

i changed the fuel pump hoping this was the reason of the low fuel pressure when the cars warmed up.

any ideas??????

should i change the fuel pressure regulator????

been like this for 2 months, takes weeks to book in the garage.

would it be worth booking into ford??
