Hi,

I put on a new backbox onto my polo, after a few weeks it started sounding like this:

WTF is that rattle/echo sound coming out of it? The box is secure, heatshields all ok so im guessing its the box ...

Month old backbox, taken it to a local garage and Kwik-fit. Both said probably the box as they cant see anything else wrong.

Any ideas what the cause of this might be?

Didnt sound like that when i put it on. All joints are sealed and its not rattling against anything. bad backbox?



Cheers
