    Check your brake calipers aren't sticking!

    Could be a fuel problem. Get a wifi obd scanner and Carly BMW app. Look for problems with fuel mix - 'might be running rich?

    Don't take it to a main dealer - total waste of money if you don't have a warranty. Find a good specialist bmw garage - plenty out there depending where you live?
    That's good advice get a scan done and see if anything comes up always the best place to start or you will be chasing your tail. I would say though if I'm town driving I don't get more than 18 the auto box is a bit of a mpg killer around town

    I'll disagree with everyone else, i don't think 15mpg in very heavy traffic, assuming bumper to bumper traffic is cause for concern. As said i have a very healthy N53 which is supposed to be more economical and i'd get 18 in that kind of traffic.

    21mpg on the motorway is not right though, you should be seeing early 30's at least.

    I have a pretty basic obd machine which I have used to scan but it did not bring anything up any codes, would this Carly app check everything? also would any obd wifi scanner work?

    Thanks, I am based in Holborn so will have a look round for some garages if all else fails to fix the problem.

    Not sure if carly would show you more, it might.

    No you can't use any obd wifi scanner, you need a carly one which is a bit more expensive.

    Its time to ditch the ultimate 6 pot BMW and downgrade to the poor mans 2.0L.

    There will be no difference in driving comfort between 2.0L and 3.0L if driving bumper to bumper but you will enjoy about 25mpg even with the auto start /stop switched off.

    And i believe both engine will work equally hard

    In bumper to bumper traffic you mayaswell be driving a ford fiesta :P

    I'll have a look into the Carly one!

    I may actually look into a 2L, with a black box installed there is not much use for a 2.5L plus it will help bring down my insurance cost i guess

    Insurance can be pricey i guess, especially in London. I never minded too much, got a 328i sport when I was 21 and it was £1k+ to insure...but was well worth it.

    Keep the 6 pot. Ditch the black box. Let it howl!

    You got lucky with insurance. Insurance in London varies between postcode.
    I waited until 25 to insure a mk3 golf VR6 and that was £1500 with a mileage limited to 6k
    At age of 21 most company would not even insure me on that car.

    I pay £550 to insure a 320i SE with full NCD and no claims. Same car in at my dads house in southeast London cost over £900.
    Insurance on a 330i Msport is well over £1k at my dads postcode.

    When i visit my dad the speed limit is so bad with speed bumps i never get chance to move higher than 3rd gear.
    I honestly cant see anything special a 330i can do better while crawling in traffic and drinking shell V max at £1.30P/L and return under 20mpg.


    Driving these car in open road can be rewarding and return decent MPG.
    But I am curious which part London you live in that lets you enjoy the large engine and return high MPG ?
