I have a question. I just got a 1.4T Touran. When I first start driving, the fuel consumption display shows over 20 liters per 100 kilometers. It only starts to decrease after driving for 10 to 20 kilometers, with the lowest being 7.5 liters. Is this normal? Is it the same for you guys?

Why didn't the fuel consumption decrease when driving a Touran 1.4T manual on a long downhill in neutral?

Hey folks! Could you tell me if a Touran 1.4T manual manufactured in February 2015 is a 2014 or 2015 model?

I just got an '11 model. I'm in the process of getting everything in order. The car runs fine, but the fuel consumption is shocking at low speeds or when starting. Even when I barely touch the pedal, the instant fuel consumption shows 50-99. When I'm at a stop on a downhill and put it in neutral to let it roll naturally, it still shows 30 instant fuel consumption. I don't get it.
