Mpg for c220 cdi amg sport plus coupe

[stevenyoungguns]

Hen I bought my coupe at start of 2013 I was averaging 60mpg. It had it 1st service 4 weeks ago and now I'm now luck to get 49mpg. Car has been checked by mercedes twice and run the usual tests but they say nothing is wrong. Has anyone had same problem or idea
