Hi all, I've got a 2014 Citroen C4 Picasso (B78).
Whenever I go over a speed bump or sharp bump, I can hear a single 'rattle' noise (not constant, just once each bump).
It sounds like a heat shield rattle, like really thin metal.
It sounds like it's coming from the right hand side of the car, but the exhaust is on the left side.
I've had a quick look under the car and I can only see the exhaust heat shield exposed on the left side of the car right at the backbox of the exhaust, but it doesn't feel loose at all. The rest of the underside is covered in plastic protective panels.
If I bang of some of the plastic panels, there is lots of small road stones trapped in them that fall out when I hit it.
I'm trying to identify what the potential rattle sound is coming from.
It doesn't do it in normal driving, only when going over a harsh bump or speed bump.
It sounds like it's coming from somewhere behind the driving position (not the front of the car, but middle or back).
It's not a rattle that makes a few rattle sounds each time, it appears to be a single thin metal sounding 'ting/clink' noise.
I've checked the rear brake shields and they're not loose.
Is anyone able to tell me where there are potential heat shields under the car (ideally on the right side - driver side in UK), or anything else that could potentially make that noise?

I'd suggest taking all the plastic covers off. Sounds underneath the car can resonate and echo to the point that the actual area is no where near where you think. I've just had a RH RR wheel bearing go but was sure it was the left.
