chirping from engine! ??

[Luciano]

My car has just began making a chirping (as in sounds like a bird tweeting) under the bonnet.

Any idea what this is?

Cheers!

most problably belt squeel caused by dry belts...best thing get some belt lubricant and anti squeel spray but make sure its anti slip. i had it before on my audi and the rx sprayed some on and cleaned the belts eliminates squeek and squeel sound from engine bay.
