Annoying rattle

[Allicia8]

Hello all! I have a 2011 IQ that has just developed an annoying rattle that is noticeable on bumpy roads (seems more so on O/S front) or when the car does that vibration thing around 2000rpm.

This is a tinny rattle and sounds to me like a loose heat shield or something similar. If the road is really bumpy it sounds like there is a load of loose change under the bonnet!

I saw an earlier post regarding a loose exhaust heat shield but when I look under the car I can only see the plastic trays at the front or the heat shields above the exhaust on the car chassis. I haven't jacked the car up so not the best way to check but wondered if anybody had any ideas.

Thanks in advance.
