Metalic rattling noise at 6,000rpm

[BJJO]

I just had a big chunk of my front suspension replaced under warranty from Arnold Clark, but when I got the car back the weather was crap so I didn't drive quick for about a week.

But now after 6,000 rpm its developed this rattle which sounds just like this: https://www.youtube.com/watch?v=D-xz6Res1nM, but for some reason it doesn't pick up when I am recording it.

It didn't have it before, anybody have any ideas?

Edit: happens in every gear.

It seems to be coming from the right hand side of the engine bay...

Strange that it just started happening, but it sounds like the noise a lot of people report, including me.

So you had it from when you picked up your car? How long have you had it for?

Yeah, the only thing that I could think was they might have not tightened something up properly or bashed something.

Does it happen at the same RPM in every gear?
