Yes, I have found something similar. Nearly all my driving is local/town and I used to get 21mpg, went in for the 60k service and now I seem to be getting 18mpg. Only thing that has changed is the weather has got colder unless this has had some effect.

Seemed to be ok when out and about during the worst of the weather.
Went for a steady drive up the motorway today, fingers crossed to see if it had any effect .... 18.5 shot up to ... 19

Might have to get it remapped at Bell Autos Services, if Guy Salmon Wakefield can`t find a solution/cause.

Let me know how you get on, that's where mine was serviced from incidently. There isn't a huge difference but enough to be noticeable since the service. I do get 26ish mpg on motorway, where it used to be closer to 30. One thing to remember is the trip computer gives you an average consumption till you rest it again. So if you do 200 miles local driving and then 10 miles on motorway the consumption figure will still be equal to what the the urban consumption is. Unless you reset the computer soon as you get on motorway that will then tell you what you are actually doing there and then.

Recent comment in regards to fuel consumption, have not set the computer at the start of a motorway, but allowed the computer to keep adjusting as one travels the highways, good idea will reset at at the start and report back.
