So I’ve just purchased a 2009 2.0 tdi coupe, just over 140k. Seems to be driving well, apart from the outside drivers door handle stopped working then miraculously started working 3 days later!! I’ve put a full tank of fuel through it, cost £73 to fill it approx 60 ltrs diesel, was expecting around 600miles out of it however I got 447 miles, which I’ve calculated at 34ish MPG, which, in my opinion, is pretty poor for the engine and the dash display is showing 44.8mpg average ??? Firstly am I correct in thinking 34 is poor for engine, second any idea what could be causing, I assume the computer measures fuel going into engine somewhere around the filter area so a leak somewhere could be possible?
