I have this noise coming from the engine bay, and it sounds like Morse code, but I'm not too sure what it is or what's causing it.

Can anyone help me, please? And thank you.

 

is the engine running or not ?

 

I can hear a chirruping that sounds like a dying bearing and a about half-way through a faint "bong" but otherwise It's mostly wind noise and birdsong.
If the birdsong is louder than your engine, that's one quiet engine!!

 

how is your speakers doing? - they can cause noise with the speaker that is trashed in the door

 

Is your alternator running fine? Mine made an odd ticking sound before it died. When was the last time you changed the timing belt pulleys? At the last timing belt change?
