Diesel engines are more thermally efficient than petrol, so much so that they often need an auxiliary heater so you don't have to sit in a cold car for ages in the winter!

On the D3, that is diesel fueled and sits on the coolant circuit. In the summer this won't activate, so 12 miles to get "warm" doesn't seem unusual?

Thanks for that, it makes sense. I had a 3.0l x5 previously so guess I was used to that. Will be interesting to see what difference winter makes.
