I have seen a few threads about a whining noise on the ML270 CDi occurring when accelerating hard, possibly with some steering lock on at the same time.
I had this issue and first thought that it was coming from the gearbox, or transfer box
The noise would go away after a few miles, or on restarting the engine. It turned out to be the power steering fluid fractionally low. Topped it up and the noise disappeared, so thankfully not anything more serious. I did read that one owner had his gearbox rebuilt and the noise was still there. So this is to tell everyone who has a noise to make sure that the power steering level is on the top level mark.
Happy with such an easy fix, I then drained and refilled the power steering system with fresh fluid.
