  1. M235i vs M240i economy

    BMW 2 Series Forum - Technical Talk on the BMW F22
    Hi, I'm looking at buying a M235i or M240i used next year. I do around 12,000 miles a year driving, mostly on A roads (dual and single carriageways). Is there a noticable difference in MPG between the 2 engines? BMW claim 37mpg and 39mpg respectively but obviously that is normally not very...

    Very sad for the family of the victim and of course my heart goes out to them but things are clearly tight in the economy when the vehicle of choice for a drive by shooting is a bicycle!
  4. 2003 530D 222k miles.Rough Running-Dreadful Economy

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    For sometime the economy had been getting worse. I had also started to get a dreadful knocking from the left-handside when pulling out of the drive although it disappeared within half a mile or so. However the car was still running rough as if one or two injectors weren't working properly. The...
  5. Please help - poor fuel economy

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    Hi all, I have a 520 d F10 2011 plate no mods. Fuel economy is really poor and I only seem to get 25 mpg for local travel around between home and town and work (4 miles away). If I use some slightly urban roads it can increase to 30 mpg but this is still so bad in my opinion. Can someone...

    Hi, I've recently found my emissions are really out of wack and my fuel economy is terrible. I've done a full service and engine flush, replaced the mass airflow meter. I have an intermittent fault that I think is related and that is that now and then when I set off I have what feels like a...

    BMW 1 Series - Tech Talk For All Gen Of 1 Series
    Had my 2012 F20 116i for about a year now and a few month back I realised my mpg dropped from 38 to around 26.8, I originally thought it was due to my remap but after later inspection I found out the remap I got should have increased my fuel economy if anything. Just wondering if anyone has had...

    BMW 3 Series - Tech Talk For All Gen Of 3 Series
    Hi all, Don't really know much about cars at all if I'm honest. Decided to check my coolant temperature the other day purely out of curiosity for the unlocked menu features and saw that it was sitting at about 62 degrees after a 50 minute drive home from work which I know is pretty low. Now...

    BMW 3 Series Forum - Technical Talk on the BMW E46
    My car can't reach 300 km with the tank filled up... I don't drive like mad and i drive 90% in the city. I think it should be below 14 litres/100km.

  14. 2008 330I economy?

    BMW 3 Series - Tech Talk For All Gen Of 3 Series
    Time to change my 2004 E46 330D manual which I have had for over 5 years and unsure what to get next. Been looking a late 2008 330I with efficiency dynamics as the economy looks good on paper and not much worse that my current car but what's it like in the real world of ownership?

    Hi All, I have just got my car back from having a fair bit of work done and it's all good as it was before it went in, and in fact since I bought although it was already high mileage then. Thing is I had a courtesy car that was an e90 320d same engine same power similar mileage. The e90 just...
