F31 330d xdrive economy - not great
Discussion
Drama Queen.
37mpg average is good imho.
How are you finding the engine compared to the 35i?
I went from 35d to 35i and much preferred the 35i.
My average went from 35mpg down to 30mpg, so doing 15k miles a year it was around £5-6 a week at the pump.
Still hated seeing 30mpg on the dash though, wish it would say "extra cost per day = 70p" far nicer to live with!

Haha fair enough. I'll quite whining.
Obviously I prefer the 35i but the 30d suits this cars relaxed attitude well and loving the XDrive in this weather. The diesel sounds meaty and sounds much better than I thought, but is a hell of a lot lazier than the 35i. Probably a good thing as I nailed the M135i everywhere. With a CSL in the garage this is a better all rounder for my needs. I'm very impressed, but want 40mpg!

2016 BMW 330d Touring X Drive 4000 miles. 60 mile A road commute. Odd blast but nothing stupid, 37mpg.
Bit disappointed. Reference is M135i which got 31mpg and MINI Cooper S which got 42mpg. Both did 83-85% of quoted combined , this is doing just over 70%. Also takes forever to get up to temp, but guess it's cold. Cause for concern or am I being a drama queen?

Rwd f30 330ds get into the 60's mpg a few chaps on the bummer forums have a genuine 70's mpg brim to brim on long trips. It's an epic engine.
My 535d takes about 10 miles for the oil to get up to temp. Once up to temp MPG is high but getting to temp it's low.
Do you haul ass or go for steady eco driving?
My X3 3.0d - 33.4 over 3500mls - on a steady M-W run about 35
My 325d - 42 over 12k mls - on a steady M-W run about 45
Both are about 80% of the advertised figures...
So your car is about right!
As for ECO-PRO - all it does is dull the accelerator pedal so more economical if there are a lot of speed changes. On cruise it will not alter mpg a jot as far as the engine is concerned. There is an ECO-PRO setting on iDrive that dulls the air-con or not but I have switched that setting off.

I think something is almost certainly wrong. On a similar route, I would expect mid 40. High 40s, perhaps even just into the 50s if taken gently with fairly free-flowing traffic. Mine is an F30 335d xDrive. My long term average is close to 40mpg with many shorter drives, in a hilly area, and driven with enthusiasm.2016 BMW 330d Touring X Drive 4000 miles. 60 mile A road commute.

Mine would get up to operating temperature in about 10 miles in the current climate. There have been odd reports of the 330d xDrive getting slightly worse economy than the 335d xDrive, but your figures are a long way below normal.

This journey was from the South West to the North West all on motorway with the average speed severely impacted by loads of bl@@dy roadwork contraflows!
For a car with such performance , economy of this ilk is awesome in my view. An amazing mix of capabilities?

Those numbers mirror mine for the F10 535d pre eco pro and stop start plus 299bhp unit. So extra weight and Aero drag of the 5 over he 3 doesn't account for the x drive sucking you off.

Worked out MPG since I got it. 36.4mpg in mixed driving vs 31.5mpg in my old M135i
My commute is 50 miles each way, mixed motorway and A roads... got a 340i, does 30mpg. Pretty happy with it, wouldn't go back to diesel, auto box and engine are really smooth. Sounds better when pushed too wish is all pat of the experience for me.
Coming from a 320d where I was getting 45mpg it's a no brainer... yes 15mpg difference but I am an enthusiast! I enjoy any kind of driving, so petrol even for commute is my preferred option.
Saying that OP, your mpg for the speeds you where doing seem pretty decent.

50 miles each way and you've for a 340i! I salute you sir!Coming from a 320d where I was getting 45mpg it's a no brainer... yes 15mpg difference but I am an enthusiast! I enjoy any kind of driving, so petrol even for commute is my preferred option.

I do same commute albeit slightly lesser miles (40 each way) and got a C300 Hybrid (decent specs on paper and pretty punchy for what it is!). I'm getting high 40s-50mpg easily but still spend about £50/week for diesel which hurts a bit.

As I allways say the 3ltr derv non x drive in my experience is better on fuel than the 2 ltr derv id get that 45 allday long im my 330d power/mpg is pretty good to be fairComing from a 320d where I was getting 45mpg it's a no brainer... yes 15mpg difference but I am an enthusiast!

Not sure what could be wrong, but the combination of taking a very long time to heat up, and poor fuel economy sounds like the symptoms of a thermostat failure. Perhaps someone here with more technical knowledge could advise.Worked out MPG since I got it. 36.4mpg in mixed driving vs 31.5mpg in my old M135i
The gap between those two cars doesn't sound right to me either. I got mid 20s from a loan M135i vs 39-40mpg from my 335d, driving in a similar way, and your 60 mile commute should favour the Diesel engine.

I used to get better MPG from my 335i than my 535d. The gap between those two cars doesn't sound right to me either. I got mid 20s from a loan M135i vs 39-40mpg from my 335d, driving in a similar way, and your 60 mile commute should favour the Diesel engine.
On the school run of 6 miles it was considerably better.
Diesels take an age to warm up, cold weather and winter diesel really doesn't either.
It takes around 1 mile for my current E350 petrol to get to 90ºc, even in winter, the E350cdi before it was still not up to temperature by the time I got back from the school run.
The E350cdi before used to take around 26 miles before the mpg started to slowly climb, which tells me that is how long it took for it to get fully up to temperature.
For many people I bet they never do many journeys longer than 26 miles.
