D5 – really so great

Hello municipality, I’ve had my D5 for a good month and am “satisfied” at the most. I have heard and read so much good, maybe the expectations were too high. My A4 Avant, 1.9 TDI (without pump nozzle) had the same driving performance at about 1-1.5l lower consumption and admittedly lower weight. My C70 2.5T was much more elastic, I don’t need to talk about the driving performance and the extra consumption of 1.5l/100km could also be accepted; that all rdings with the same weight. I only drove 4000km, maybe something is still happening, but when I step on the gas in the 4th gear at 2000 rpm I expect a 5-cylinder with such enormous torque much more. What are your experiences, something else? Thank you and greeting Marvin
