I have averaged just under 40 mpg, (& this is getting lower, from about 41.5 in August), since I bought my 06 220d about a year ago, but some of this is probably due my using Millers DPS 4 since mid-July. I had the 5th injector change & ecu remap in mid-Aug. When I had this done I queried the EGR valve & was told that it wasn't something that was normally changed.
If it weren't for these factors I imagine I would probably now be somewhere around 37mpg average.
I can now only achieve 40/42 on a run if I take it very steadily and keep an eye on the revs all the time. If I drove it "normally" I reckon the consumption would be below 40, again somewhere around the 37 mark, or maybe lower.
Can any one tell me if the consumption I'm now getting is reasonable and if I should be able to get the injectors, EGR & bleed down valve changed, and will this improve things. Or would I be wasting my time?
Many thanks

Guys,
Went to the dealer yesterday and they ran a diagnostic which showed nothing was wrong with the car. The lady at the service desk was a little unhelpful and stated again that all their demos only got 34 mpg and it was normal. She said the figures were based on perfect driving conditions with no environmental factors! I mention the EGR and the bleed down valve and she stated they did not need to be changed. The car came back washed but I feel I wasted a Saturday morning and am no closer to a result.
I mentioned that a guy at work has the same car and he gets in the low 40's and she suggested I let him drive my car to see what he got. I think I will try the dealership in Plymouth where I am working at the moment and see what they say.
