Need Help!! Loud Engine when Idle!

Hi guys,

I really need some help as I am worried about my car! I've got a 2.0 TDI Audi A4 & it's done 145k. Over the past day there's been this really loud sound coming from the engine and i'm not sure what it is.

IT'S A VIDEO SO CLICK ON IT

Here's a link:


I've been doing some research into and most people say that 'they need to hear the sound' the car doesn't shake at all, it's just really loud!

The engine only makes this noise when it's idle, when I slightly press the throttle it goes away.

It's only recently had the cambelt done & got MOT'd in May.

On my MOT there's something that might be of help, they've put ' Under-Trays fitted obscuring some underside components'.

If you need anymore information then let me know. If that link doesn't work I will try to post another.

Regards,

Dom
