Sorry to respond so late, I've been back to good 'ol Chicago for 211 training (new e class)
Haven't had alot of complaints like this, and to tell the truth I'm lousy at diagnosing a "noise" complaint without personally hearing it.
A few ideas would be that I've seen the front exhaust bracket crack on these, that can give a noise on acceleration like you describe, and also we've had a few catalytic converters making noise, the matrix inside the converter can crack and vibrate at times. It's not covered under the 80,000 emission warranty as it doesn't cause a check engine light or affect emission performance, just annoying.
