my daughter is moaning because she reckons her 330i is using a lot more fuel 24mpg V 28mpg after it was serviced and had an update by the dealer. anyone else had this or is it her imagination?

It should not decrease the MPG unless DME (engine) module was update and there is no reason for them to update it. Unless there was ongoing problem with the car.

I reckon they have reset the mpg counter and it will take few days/ miles to get the correct values.

if its any help mine was always 25.9. even after resetting, eventually it would rest on 25.9.

Perhaps the cold weather has been a factor?

The cold has certainly made a difference on mine

Definitely has to be factored in as temperatures drop. Plus any OBC resets will show difference on a shorter term averge, at this tme of the year.

Cold makes a difference but more so with diesels.

My N53 330i averaged 34.0 mpg over a period of many months, then had new injectors/coils/remap (dealer said the very first N53's ran a bit lean) and the MPG afterwards has been.................

34.0 mpg.

Where were you driving mate, in a vacuum at a constant 56mph?

I do up to a thousand business miles a week. That means a lot of time on the motorway and I usually set the cruise for an indicated 80 or 75 which gives me high 30's for a journey with not much other driving at each end. 42mpg for a trip the one time I was really trying to drive like a saint. I have had 33-34 mpg averages for the last 50k miles in this car.

The other driving I do often sees full throttle/revs but I almost never use the car for short trips or town driving, and if traffic dictates I can't have fun I try and drive as economically as possible. The fact I just changed my brakes for the first time at 70k shows I am pretty light on the brakes, then again the fact I used to track and race cars a lot and switch the DSC off many times on most journeys indicates I'm not shy of using full performance when I want to, either. I'm very happy with the car's MPG.

We use my wife's Golf for short trips, town driving,and holidays, since otherwise mine does all the miles. Incidentally this - a Golf Plus 1.6 FSi petrol - barely exceeds the 330's MPG on a long run - indeed if you start to cruise at more than an indicated 80 the 330 is more economical, especially loaded up! We get about 39MPG out of it normally. If my wife drove my car she's get that out of mine!

Thats a quite fair few miles you do there chap. I owned an E90 330i Up till a month ago, had it 4 years. 25.9mpg for me. hence I was shocked.

Still though nice to know its possible to get more miles out of it.
