Fuel consumption and on board computer
Decided to calculate my fuel consumption to see if the on board computer is accurate. Turns out that it is pretty off!
I reset the trip odometer (and Trip B) at every fill up and it is usually telling me that I am getting between 8.9 to 9.1 L/100. Today I did a fill up and then calculated the consumption based on liters in to KM driven and I calculated 9.76/100 (or 28.95 UK MPG, 24.11 US MPG).
I usually drive about 20km to work and back with approximately 10 min of that at 120-140 kph on the highway.
First, is it normal that my on board computer would under estimate the consumption by so much? Second, is this range normal for city combined?

Also, from time to time I feel a lot of hesitation where the engine chokes. I usually keep my foot at the same level and don't lift.... it usually lasts for about 5 seconds then a few seconds pause then repeat. I assume this is the particle filter clearing, but is it "normal" that the engine chokes that bad? The first time it happened I was really shocked... it felt like it was running out of diesel and the turbo needle was jumping up and down.
