I had a similar experience earlier this year in my C200 CDI SE Elegance Saloon..
Approaching a roundabout I put my foot down as the road was clear and all that happened was the engine revved..no gear. I stopped the car selected N then D and all was right again.
I reported this to the dealer...
How strange...I had very similar symptoms with my C class...
When I had the rear tyres replaced the problem disappeared so never did find out what was causing it.
Sorry I can't offer any help.

Querying...
The thing is i had a C220 CDI Coupe before I changed over to the C200 CDI Saloon and that car..even though it developed quite a bit more power was much quieter on acceleration.
I was once loaned a C270 CDI...now that car was almost agricultural it was so noisy..but what a lot of fun driving...
I have a November 53 reg C200 CDI SE Elegance saloon with 21000 miles on the clock.
I find the car to be rather harsh sounding and noisy when accelerating.
At first I thought this was down to the car being new and that it would quieten down once it was 'run in'.
To a certain extent the car...
