Today when i pulled up at a level crossing, i turned the engine off and when the trains had passed, i tried to start the engine back up but it wouldnt fire. It just kept cranking and wouldnt fire. The orange spanner light was flashing and the pedal test showed P1614 error which i believe is to do with the key immobiliser? I hit the dials a few times and after about 5 minutes, the car started fine again and went. Then when i tried to start it again later, it was fine. Does anyone know what this is because i really dont want to get to the car one morning when i really need it and find it wont start? I hope its just the key and not the whole ECU :(
