I have a 2015 vauxhall zafira c. So a few weeks back, I started the engine, it was idling as it shouid, then about 30 seconds later the engine stopped. When I turn the key it goes to turn the engine (you can hear it trying to turn) and it stops turning and u hear a whirling noise. I hooked it upto the diagnostic machine but there is no trouble codes showing up. I tried cleaning the battery terminals but that did not fix it. I got a new battery but that did not fix it. So I bought a new starter but that did not fix it either. Does anyone know what else it could be??
