Moin, I noticed something unusual the other day when I was on the AB again. Is it actually possible that only by the road surface the consumption can change like this? And I drove from Hamburg to Soltau at an even speed, and suddenly my instant consumption on the BC changed by two liters at a constant speed (no drop or other). So I conclude that the road surface has changed. But is that actually true? I can? a whole two liters in consumption? (that would be 20% more consumption). I actually exclude my BC a Macke. What do you look like? Or did you notice something like that? Greetings
