rattle noise

[Christophe]

If i'm in third and put my foot down i have a rattly sound that seems to be coming from the engine on passenger side.

probably useless explaining

loose heat shield possibly

 

[Christophe]

is that just screwed in? Sorry i'm useless when it comes to engines. Is accessible from engine bay with out undoing parts?

 

[Christophe]

is there only an exhaust heat shield or is there another one?

it should be yes just screwed in

Accessability depends which heatshield is loose.

There just one shield its made of many parts though.

I have the same in my Clio. It also happens in other higher gears but due the speeds the rattle develops more into a low rumble noise.

My friend thinks this is being caused by the honeycomb bits inside the cat being broken and rattling around. Not being a mechanic this means nothing to me but hope this helps.
