In my old T5.1 I used to keep the heater temp at the mid point, which was 22 degrees. I’ve done 250 miles in my new T6 and I’ve noticed the van gets red hot when I set it at that temperature. I have to turn it virtually down to get it to cool down. It seems worse(hotter)when the heater is set to windscreen yet on face vents it cooler. Now I’m not sure if it has a fault and it needs to go back to the dealers. As like I say the temperature control was a lot more controllable in my old van
