My captur produced the same faults when my fuel rail blew and lost pressure. The car ran in limp mode, but the dashboard had every fault appear. I don't know why this is, but it's definitely the way both my cars operate. My Clio MK4 did the same over a bloody TPMS sensor fault. As soon as the faulty part is changed. All the faults dissappear.It doesn't mean the charge is good I'm afraid. Is the Stop-Start working OK? This will turn off if battery is low. I would give it a good charge and see if the faults disappear. These faults are nothing to do with the rad issues, but a low voltage can play havoc with the sensor inputs. If a good charge doesn't help, then it's back to the dealer again I'm afraid.
