Mine sounded exactly like that. It sounded like the noise was coming from the lower windscreen or top of the shock. Front anti-roll bar bushes got rid of it. Apparently the anti roll-bar is connected to the shock assembly in some way and the sound is transferred up through the shock to the body/top mount part which is why it sounded like it was coming from there. Took a couple of visits for the dealers to sort it out - the first time it was supposed to be fixed but as soon as I drove off I could tell it wasn't. When I took it back I insisted on taking the service manager out for a test drive rather than the useless mechanics. Straight away he said he has seen it before and thinks it's the anti-roll bar.

It was like a low tone squeak, bit like a muffled donkey, heard when going over bumps in the road, very audible over speed bumps even at a crawl, also got it when turning in to a corner.

Still have several subtle clicks and creaks but the main source of noise was the anti-roll bar.
