Warning lights came on

Hi people just been driving down the road and all warning lights flashed up. Pulled over popped bonnet engine felt really hot but the temp gauge stayed in the middle? Anyone got any ideas please????

 

Would it possibly be something to do with this hot weather?

The engine will feel very hot on a day like today.

 

The main warning triangle lights up when the ECU detects a fault, are there any other warning lights coming on at the same time?

 

The most common reason for the warning light to come on is low brake fluid, the sensor is very sensitive, even if it is just below the full mark it can come on. Try topping it up and see if that cures it.

 

I would do an ecu reset, remove EFI fuse number 1 for 30s or more.
