Hi guys,
I've started hearing a light rattle coming from under the bonnet. It seems like it's coming from around the belts area. I have no clue as to what's causing it though, so if anyone has any ideas please help!
It first started occurring as the weather started to change, starting randomly sometimes for just a second, sometimes for hours. It became more and more frequent, until now it seems to be rattling more times than not.
It doesn't seem to be affected by engine speed, but it's hard to tell as the engine drowns it out above idle.
I tested the following to see if I could work out the conditions it appears in, but to no avail:
- Turning A/C on and off
- Turning fan on/of
- Putting a load on the engine (head beams)
- Turning the steering wheel
- revving the engine
- starting and stopping the engine
It also occurs both when the engine fan is on and off.
The car is a pre-facelift 8L a3 1.8t agu engine. Done just over 100k and hasn't had the cambelt done yet (i know i know!)

YouTube - IMG 1231 (bonnet closed, a bit further back to hear the noise better)
Any ideas??
Cheers
