Why does the suspension on my BMW 7 Series creak so much?

My 2011 BMW730d suspension creaks and groans a lot, but the main dealer cannot find any cause. Any idea what could be causing it?

Inevitably bushes, but finding which ones could be a long and expensive business. One way would be to spray each bush in turn with WD40 until the creaks stopped and identify the failing bush that way.
