Its strange how this issue causes everything from minor blips to full failure. I don't know wether it will help or not but I'm only using V Power fuel which is designed to help clean the injectors and the engine as its used. Since buying the car my first tank was 95 RON, my second was 99 RON V power and the mpg is increasing, I will post the results everytime I fill up as I work it out tank by tank to give an exact trend. The 99 RON fuel is not improving the tickover sound tho, I prefer the sound of my Dad's 520D!
