Hey guys, so basically I own a 57 plate 3dr Vauxhall Astra MK5 model. Now earlier on today, I had been driving about as I normally do for about 10 minutes then I parked up while signing some papers leaving the car on for another 10-15 minutes. Then I'd driven for 3 miles to go and post something and when I get there I've turned the car off but as I've turned it off, I heard the fan at the front of the car still running (engine fan I'm guessing). After a minute, it the fan stopped so I continued doing what I had been doing.

When I got back 5 minutes later, I started the car and the temperature light started flashing. I thought to myself let me at least get the car home and on the way home the light turned off. When I got home and I heard the fan running again and thought the engine just overheated so I left it for a few hours.

When I got back to try and drive it to the corner shop, It started but with a struggle but I couldn't drive it for another 10 seconds before it completely died on me. After that, the car just wouldn't start and kept ticking when I turned on the ignition as if the battery was completely dead. I tried to jump starting it and it ran for about 15-20 seconds while I revved it before dying again and couldn't be revived. Now a quick back story about this is that my batteries green light has basically been non-existent since I bought the car as far as I can remember (August 2015). Now I was quite confident the battery was the problem until I remembered that the temperature light came on briefly AND the fan still comes on when I turn on the ignition.

I know this is quite a long post but I'm trying to get in the events that occurred so that I can give the best picture for the best solution. Also, if I've posted this in the wrong place, please let me know so I can move it. Any help is very much appreciated, thank you guys.

What's the battery voltage?
And is there any coolant in the header tank?

If the EML is not on then I can't imagine it being a sensor fault, sounding more mechanical.

When it ran was it smooth or lumpy? Did it seem to be running on all 4 cylinders?

Does it actually turn over on the key, or just sit there and click?
Might be worth trying another battery anyway if you can - just to eliminate it.
Might be 12V off load but collapse when you try and draw current.

As far as I can remember, the ride was smooth, there was nothing different about it. I don't know how it would feel it it wast running on less than all 4 of cylinders, sorry not that techy with cars, I know pure basics lol but I can search up stuff.

When the problem started happening, it turned over and the fan came on but as times gone on it just sits and clicks - no fan.

Yeah, I'm going to go halfords today to get a new battery. Hopefully that's all I need fingers crossed.

And I'm sorry but that last part made no sense to me loool ?

Right so so far, I've bought a new battery and that didn't solve the problem and I tried unplugging the MAF Sensor and neither did that do it. Only difference is now with the new battery, it attempts to start and does start with a struggle but dies in 2-5 seconds.

Puzzled now as I can't find anywhere where it mentions a flashing coolant light. It normally just comes on red when the engine is dead.
Can't see it having boiled if there is plenty of coolant though.
