Replacing the coil pack in my 2007 BMW 1 Series gave better fuel economy.
I thought you may like to know of some problems with my BMW 120i M Sport 07/57. About 12 months ago the "stop/start" feature stopped working due to a faulty low fuel pressure sensor. Then a month ago it started to "stutter" under acceleration. After a software update it was found to need a new coil pack. Both problems were rectified under warranty. Strangely I am now getting 5mpg better fuel economy.

If the stop/start was not working properly and a coil was faulty then this would have affected the fuel economy.
Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
