OK, I know that we no longer have a formal "running in" period for cars these days, but various threads have commented on the effect that is noted as the (diesel) engine loosens up with use.
I have just transcribed some "brim to brim" average consumption data from the log of our W 203 C 220 CDI AG Estate auto, and thought this may be of interest.
Mixed motoring, one driver, all fuel from same source so as many of the variables as we can stabilize have been addressed.
0-5,000 miles - 38.66 mpg
5,001-10,000 - 40.92 mpg
10,001-15,000 - 48.18 mpg
So those C class owners who were disappointed by their initial consumption should take heart. Dosco reported, in a separate thread, a brace of E 220 CDI manual saloons which can average 57.1 mpg and giuseppe has seen over 60 mpg in his E 220 CDI, although I think all of these cars have 6 figure mileages to their credit.
It seems that the further you go, the better it gets.
