That's like asking how long is a piece of string.

Could be anything, your best start would be to get an ODB reader and see what codes are showing.

That sounds like knock sensor failing, damp gets into sensor as car stands overnight so it throws the light on, as the engine heats it drys out the sensor and light goes off.

Obd reader wont work on your car, you need to connect the diagnostic plugs under the steering column to read the fault code
