My car started over heating out of no where, the rpms run high, coolant leaks but I can't tell from where, suddenly.my oil light came on and my oil was perfectly fine with full synthetic oil..and I came to a light and car died . My Audi A4 2003 has not started. I put a battery charger on it overnight and it turns over with a light revving notice but car does not start and then battery would die again. Help help help what's wrong with the Audi I just bought
