Hello all. I have a 10 plate 1.2 petrol , I have stop start unavailable coming up, I have had a brand new battery put on, I have changed the ibs from a car I know that is working well on, after about two miles of driving the stop start warning lights come on and unavailable on the dash, I’ve ruled out the battery and ibs sensor so I’m stumped as what it can be. I’m also getting a permanent fault reading B1047, it will not clear, the ibs fault code comes up but that does clear. Any ideas guys ?
