Question Re: Renault Laguna II - Phase 1 - Engines - Average MPG from 1.9 DCi Engine

I have a RENAULT LAGUNA DYNAMIQUE DCI (130) 2006 1870cc Five Door Hatchback Manual Diesel

Town driving I tend to get 43mpg, and don't tend to exceed 2000 revs at all

Motorway I tend to get 47mpg - 49mpg

The thing is, when I got the car in 2009, the mpg was higher, 49mpg around town and 57mpg on motorway. I am trying to understand what has caused the decline. Glow plugs and re-programming of the injection system have been mentioned in this thread.

Is there anything I can do/check to try and get to the bottom of my issue; so that I don't go to the dealership and just generically state, my mpg has dropped, can you improve it?
