hi.
so problem seems to me is very big fuel consumtion.... 100% urban driven with allowed 50km/h some roads are 70, but in idrive average consumtion is 13 - 14 L/km
i know that possible one injector is at border reading by diagnostic tool.....
can U guys share with Your fuel consumtion? maybe U have any idea

thanks for help.
i know my english sucks

 

What diagnostic tool did you use and what is the test that you used to see what the injectors are doing?

 

bosch KTS dont remember the numbers....
there is fuel correction amount and there should be number in range between +4 / -4

 

Hello Mate,

In the city mine takes 10- 10.5...
On motorway much better 6.7

 

1. Check your REAL consumption. iDrive can be wrong.

2. Check your real consumption out of town

I currently have a consumption of 13.6L for the last full tank, driven only in the city, but bear in mind that my traffic is horrendous. I spend probably 70-80% of the time waiting on traffic lights and in jams, and only the rest actually driving, and its mostly stop-and-go type of driving anyways.

Out of town my car consumes 7-8L in the winter and 8-9L in the summer. E61 530d.

 

mine is much more then than Yours ....
is it possible that one "not working injector" make that excessive consumtion?

 

yes out of city it was reasonable consumtion, last winter..... see what gonna be in this winter.
ok, i have allready lot of traffic jams and waiting green light, but at my road to job have few lines where driving speed acceptable is 70km/h, not much but anyway....
and at first time when i buy my consumtion was 11.0 - 12.0

 

Looks like as other members suggest, worth to check the injectors for sure.
i only changed the fuel filter, and used a German brand suggested

LIQUI MOLY
by my mechanic to clean the injection system, adding into to fuel tank with correct proportions.

do this checkes, and let us know how things develop.

but if you are driving all the time BMW way, arround a 200km/h your consumption is OK!

 

200km/h thru the city

kill bill 3

 

I was also experiencing around 13-13.5L/100km in my 2005 530d Auto (with a SprintBooster) when doing city driving. After having the Wetterauer Remap (from 218ps to 265 ps and 500nm to 580nm) it was drinking around 10-11L/100km in the city. My 2007 525d Auto with the new LCI auto gearbox was MUCH better; it never made it to double digits, even in the city. Simple truth is that these pre-LCI 530d autos are not that fuel efficient around town, especially in stop and go. The LCI version is much better, well at least from my experience.

(Which is another reason why I got the V8, because I wasn't exactly saving much fuel in the diesel. The V8 drinks around 14-15L/100km in the city, which is not that that much more than the 530d)
