    So, have just fully filled the car for the second time since having it one month, so able to do an initial calculation.

    At 410 miles, showing 1/4 left, it was 45.9 actual, the car showing 49.1. So the usual 10% over estimation that most trip counters display. It has been in eco-pro (with s/s disabled) most of the time and showed a 'gain' of 28 miles.

    I'd say half urban commute of 6 miles each way, the other half having an hour-ish journey at each weekend leisure trip. This reflects the likely duty cycle it will endure while it lives with us.

    Even though it is a boxy shape, the cd is 0.26 so fairly aerodynamic, but counteracts this by being a bit heavier than you'd guess at 1400+kg. I did hope it would be a tiny bit better than this, it takes a much longer time to warm up than I thought, which really can't help. Not the end of the world though, I didn't buy it solely for the ultimate economy.

    I think those are good figures for the type of journey you are doing. My old 2012 320d (N47 unit) with the ZF6 auto box managed 46mpg over 10k miles, actual mpg, but a lot of that was longer runs.
    The derv is designed to warm up and sit at speed, shorter runs won’t ever get the best economy.
    Maybe a cheeky remap may help the economy.....

    Not bad economy for a 2 AT. My old 320d only managed 38mpg long term average, but on a run would get around 45-48mpg, but it was remapped and a 2008 model, the later 2.0d engines were a bit more efficient.

    that is not bad for what could probably be described as extra urban. you will really see what it will give on a long motorway run you will get 60 plus at a guess which is not bad MPG

    Thanks everyone, I'm glad it is near the mark that others deem acceptable. I seem to realise it is a B47 with a ZF8.

    It is all swings and roundabouts really, 218i would have been £50 a year cheaper to insure - probably the amount I will save on fuel over 8k pa mileage.

    In the end though, it was just a case of the 218d being the most popular model, so when buying used it just happened the car which was 'the one' happened to be diesel.

    ps, better not mention EGRs & DPFs :unsure:

    Don't worry about the DPF etc. I've ran a 520d for 8 years now mainly short journeys, no issues .....now on 140k

    The gist I get nowadays is that modern DPFs are more reliable than those of 12 years ago. I had to replace the DPF on my old car at 145k miles.

    I wouldn't worry too much, during a 6 month time period I'd been getting dpf soot loading errors, had performed a lot of active regenerations. Errors went away but came back shortly after. Engine temps were fine, very few short journeys and thermostat working correctly. I just think that dpf had reached the end.

    Replaced it (fortunately found a genuine one in Germany for half normal price) and it was fine ever since.

    Current 2014 335d I'd expect to last closer to 200k before needing attention.

    Regen/emissions tech has definitely improved over the years. Didn’t have so much as a blip with the N47 in the last car. I couldn’t even tell when it was doing a regen as I drove the car, unlike the previous generation of (Fiat derived) Saab diesel I had, even with lots of longer runs it was a nightmare, regen a failing, swirl flap bar dropping off etc. That was a 2005 designed engine in a 2008 car.
    I would se this a lot:
