Remapped ????

[chelsea owner]

Hi all, pretty new to all this so bare with me :)

I picked my new to me x5 d sport 05 up on friday, Im very very happy with it !

The previous owner said it may have been remapped and I just need to run some mpg figures by you all to establish the possibility.......here goes mpg figures so far......

On the motorway.......

@65 mph over 10 miles its doing 42 mpg

@70 mph over 10 miles its doing 38 mpg

@80 mph over 10 miles its doing 34 mpg

daily commute of 24 miles round trip on steady going B roads im getting 32 - 34 mpg.

not complaining at all and I am only asking as the mpg seems too good to me.

cheers for any input

p.s. I really dont want to rolling road it.

is this an obc reading or brim to brim test,coz the obc is prob wrong,mine always reads 6 mpg better.ie it says 46 in summer and i only get 40 brim to brim,and most other owners are the same but varying in the discrepencies
