Help Please - Noise From Engine Bay

Hi there guys, first post on here so go steady with me. I've had my Landrover Freelander 2 (08 Plate) for around two years now, during which time she's performed without any issues at all. And without doubt, this is the best vehicle for pounds I have ever purchased

However, I was coming home from work tonight and I noticed quite a loud noise coming from the engine bay. At first I though it was the radiator fan because the catching noise was coming from the front of the engine. After a little more investigation I discovered the part which was causing the problem!! The issue I have got, is I have no idea what it is? Can someone please tell me?? Attached are the two pictures of the bit!!!!!


Thanks Guys
All the best Darren

Hi can you take a more general shot of the engine bay and then highlight the affected part so I can try and work out what part it is.

Thanks

Hi
I have just experienced the same problem today. Did you get to the bottom of what the issue was?
