Vibrating Noise. Need Help

Hi everyone

There's some nose in my car that's really driving me nuts. I really can't find it. You can hear it inside the car when all doors are closed. It's like somethings are hitting each other with the car's vibration when it's idling. When you open the hood, you can also hear it and it's coming from somewhere near the alternator and the back part of the engine.

Any ideas what it may be? I really need help. This is driving me nuts.

Car is a 155 2.0 TS 16V BTW. And thanks in advance.

I tried removing and refitting the alternator but the noise is still there.

Can it be the exhaust? The downpipes join on to the Cat back there... I think there's a flexi section too. If it's loose, it may be banging against the body, or it could have a hole in it, which may be making the "knocking" noise.

Is the Alternator okay? If the bearings are knacked, then it may "knock" too.
