I noticed this morning the car took longer than normal to start up around 3 seconds from instant. Did the same leaving work, filled up with petrol on the way back as it was near empty then started up perfectly. So I got home and left t for a bit now it's not turning at all. As if it might be the battery as it's not turning? When I turn te ignition to try and start up the needles(on the dash temp and petrol needles) flicker and go back to normal. Anyone know what the problem is?
