I was wondering what kind of MPG I should expect or how I can improve it?
Also is remapping going to make any difference to fuel economy or is it just hype.

 

22 - 31 MPG for the average driver.

Depends on how you drive and the journey. Firstly these figures are on board dash figures. If its a long motorway run at a constant 70mph the dashbaord figure you should get is about 45mpg. Extremely heavy stop start traffic you'll get 25mpg. Typically I average between 35 and 40mpg on my commute to work which is a mixture of both.

I have noticed the on board figure is a bit optimistic and its about 3mpg higher than actual so reduce the above figures by that amount. I also have Brabus D6 fitted to my car which didn't seem to affect the fuel consumption.

If you are deciding between the c220cdi and C320cdi definitely go for the C320cdi.
