Hi,
Does this look correct to you? It looks like something has become loose.

 

[QUOTE=Hdqq;2843198]Bonjour,
est-ce que cela vous semble correct ? On dirait que quelque chose s'est détaché.

Cela me semble correct aux vus des photos !

 

Hi hdqq,
Your under-tray is very well secured. A piece of the oil and sound absorbing mat has come loose.
You could reach under the car an pull it out. Alternatively you could remove the under-tray and clean the piece of mat and re-secure it.
