I got a 2006 A3 2.0TDi 140 sport, 145k on the clock.
Got really bad mpg like 28 on average, so a friend reccomended to change the fuel filter, was a big sucsess 48+mpg!
Then the seals go on(lots of whislte) the turbo cooling system that leads to the intercooler (the big pipes) so my guy changes them all!
Also changed the 2 front tyres and now I'm getting. 33mpg!!
50pound of fshell fuel save gets me 3/4's of a tank wat give me 300 miles..
Witch in reailty gets you no where!
Tyres are in flated all round to 34psi! New diesel filter a month ago, all turbo intercooler pipes are sealed well! New tyres, good quality fuel so what could it be!
One of those things that you just think 'nightmare' and this is one of them!
All your help would be apprchiated!
