did mean to post this along time ago, while considering my next car i had a X5 40d on loan , and loved it but around town found it to be ridiculously juicy, more so than my V8 so couldnt justify paying 40k for something thats worse on fuel than a petrol espicially with diesel costing more at the pump so my question is this....has anyone managed to get theirs worse than this.......

surely it cant of averaged that??

afraid so, maybe something wrong with that particular car? but was a BMW approved used...

Surely that was just town work on a reset computer

Mine averages about 26

didnt touch the computer tbh just started flicking through it after my days driving and thats what i found...the needle did seem to drop quicker than the 4.8is too though

you musy wear lead boots!

Then it needed a reset!

Lots of short journeys, probably left running a lot......

They are not economical in the true sense of a diesel but not that bad!

well yeah i did drive it with heavier feet than usual for "test" purposes, but not by much, theres only so much you can put ur foot down on london roads in the daytime

Something definitely wrong there, be interesting to know what the use had been since the last reset, but methinks it had done a lot of idling. Only ever seen those figures if the car has been idling a lot straight after a refill and not travelled far - like less than 100metres! The figures get more reasonable within a couple of miles of normal driving. Mine averages 32-24mpg at 6,000 miles. Around town it's 28-29. Even using Sport and a lead foot doesn't give that bad a fuel use figure. I've never seen less than mid-twenties, and even that took some doing and was whilst the dealer was showing me the car functions when I was taking delivery and we had the engine running (it was dark).

That's just been moved around the dealer's yard at a few mph, but probably at plenty rpm. A quick reset would sort the true figure.

I brought a new 40d se at the start of last year. I am very pleased with the MPG and I get 37 on a run and 31 around town, all the time.

I had a V8 before and got around 14 town and 18 on a run, needless to say it was a killer.

I'm on similar figures 29 & 36 on my 40d so can complain
