Hi - the forum is new to me and I have searched but can’t seem to find a thread on my issue, not sure I’m posting in the correct place but here goes.
I have a 2004 A2 1.4 petrol. I have to crank quite a bit for the first start of the day. I discovered that if I pause with the ignition in the on position and then turn the rest of the way to crank - the car fires up immediately. Car runs and starts fine the rest of the day unless there is a long pause without use then it takes a little longer to fire up. I have changed the fuel filter with an original (including pressure valve) from Audi with no effect.
I’m wondering if there is a fuel non return valve somewhere (perhaps built into the fuel pump ?) which prevents the fuel running back from engine to tank when the vehicle is not in use. With ignition on I can hear the pump work, if I wait a moment - I’m thinking it primes the fuel system and starting is instantaneous. Any thoughts or experience ?
