I have looked on the forum for advice but it has not worked. Now fed up with Renault, my Lag 2 has cost me far too much money over a 5 year period. Now going Japanese, bring on the reliable Accord 2.4 Vtec!! Goodby to Renault forum. And goodby Sport tourer 2.2DCi
Right - your constructive post helped the original poster in what way? I appreciate that we've not all had the best experience with reliability but simply dumping your thoughts about the car in this thread isn't helping the original poster in any way with the inquiry posted.

Hopefully somebody with experience of the Lag 2 with this engine in good working order will tell you what one should achieve. We have threads on the forum for owners' MPG reports on 1.9 dCis and most of the petrols, but not the 2.2 for some reason...

Low fuel economy could be caused by a number of things - assuming the air filter is clean, and the tracking is good I'd suggest inspecting the EGR valve to make sure it isn't clogged up with sooty gunk to start with. Again, hopefully somebody with more experience of this engine will suggest further steps.
