Drop in MPG - BMW 3-Series (E90 E92) Forum

scottishpete · 01-17-2013, 01:07 PM

Only do like 100 miles max a week and drive mostly in town
last year i was getting 32mpg on average,but over last 6 months its been 26mpg on average

08 325s m sport auto 22k on clock

Should it drop this much?

26mpg driving in town sounds about right.

Could be your thermostat possibly? Maybe have a look to see what it's getting up to in the hidden menu.

I do quite a bit of town driving, check my Fuelly sig \/ as I have a 325d auto too

Just checked, and even my high % town driving I still maintain ~30 mpg, so you might have a problem.

32mpg out of a 325d?

I get that out of my 325i, surely you should be getting higher?

I do more m-way tho, probably 60/40

Definitely check the ECT from the hidden menu. Thermostat issues and running low ECT is very common cause of mpg drop off in the diesel models.

I did 130 miles today before my car got to temperature.

The cold weather makes a huge difference.

someone want to explain this hidden menu?

Hi All,

I'm not spending enough time on this forum but thought I would give my two pennies worth.

I return an average of 22 to 23 mpg in town, which increases significantly on A roads and motorways to anywhere between 32mpg upto 40mpg.

After doing 800 miles from new, I even had a competition with a good friend of mine with a 320D M Sport Touring (2009 or MY 2010) - he managed 61.0mpg and I managed 61.3mpg (I must have had tail winds and somebody pushing me).

youve got to unlock the menu first from menu 19 i think? (its the sum of the last 5 digits on your vin)
