Fuel consumption on 2007 X3 2.0 diesel

Post by mikesmith2939 » Sat Jan 02, 2016 9:14 am

Since blanking off the swirl flaps and having a new glow plug controller along with new glow plugs fitted my fuel consumption has got worse.


I have lost about 4 mpg on a long steady run and about 6 mpg on on shorter mixed driving.

Also I the new glow plug controller seems to have stopped working.

Our E46 is the same in terms of MPG.  It needs more throttle to make it go, probably due to airflow restrictions, and smokes more under full acceleration.

Acceleration seems to be the same, no smoke at all under load.
