19 00
20 00

I ran the vehicle in the lunch break... It was like four hours before. Then I ran all the channels.
Can it be that 09 has nothing to say, because the giver does not even exist?
I still have the feeling he consumes too much. so about 14 liters in normal driving mode and about 50 km at a time over the Alb.
The subject of temperature flap is identical to the one of 4.2?
