Hi, my car is x300 2008, 16.000km . Today I was travel for about 100km, all the way the fan is working and never stop, near 70 km , battery light is on permanently. I stop the car, stop engine, fan still working. I try to start again the car and doesn’t start , is like when you doesn’t have battery charge. I was trying to used another car to give energy and no start.
Battery is almost new, I was bougt in sept 2017.

What do you thing about this problem?. Thank you for your help.
