'06 2.4 jtd + Q-tronic.
on the daily short commute (barely reaches operational temp.) gives me a shocking 17-21mpg.
Not sure about DPF (the box is there, doesn't sound hollow), it seems the ecu has been tickered with before (it tells me the last regen happened 11k+ kms ago), EGR is intact.
Didn't buy this car for saving on fuel, and it still more economical than my other car... but I'd like to see better numbers.
I'm suspecting a faulty/leaking EGR, car is really sluggish at low speeds. (swirl flaps looking good.)
