Hi Xeins
Let me say a couple of things about.
1)"- When using the heat (>25ºC), the interior of the car is warm but there’s a cold vent coming from the front grill;"
1)Well, this is because of the automatic airconditioning system. From time to time send frsh air into the cabin and the temperature sensors are measuring the temp all the time.
2)"- Instantaneous fuel consumption indicator has a live of it’s on when the engine is on neutral;"
2)The instantaneous rise of the consumption indicator is because of the diesel particulate filter which from time to time consumes a litle fuel to burn the remainder particles of the exhausted gases.
I hope I was helpful!
