How does it work? Mine has a pre heat option in the remote app, it starts the engine, but it seems to run much more quietly than when it’s running normally. No steam out of the exhaust on a cold morning either.

Not sure, on the petrol it looks like a small version of the D3/4 fuel burning heater. 130's have feeling's as well you know

On my D240 it heats the cabin too and starts the heated front and rear screens - all started from the remote start function on the app. There’s no separate exhaust like you had on your FBH in Disco3 and 4 and various RRS’s - it exhausts via the DPF and normal exhaust on the diesels. I’ve found on the 2.0ltr engine that it uses about 0.5ltr of diesel for the 30 minute cycle.
Recently I’ve set it going 30 minutes before I want to use the car and even the side windows have been defrosted with the planned temperature (which you can change by tapping on the desired temperature on the app page) set at 20C - the temperature gauge is usually up to halfway between cold and normal position at the end of the cycle but the climate control won’t cut in until the temperature is up to nearl the “normal” position so I’ve used the butt roasters and heated steering wheel for the first 4-5 miles of the trip.
On really cold days I’ve only had one problem - even with the wipers set to the winter park position and defrosted by the screen heater the rubber blades seem to be to be very hard rubber that even when I’ve cleaned any remaining ice from them grate across the glass - might have to see if I can get hold of some better winter compound blades for next winter as I’m sure that they could scratch the screen. I also wasn’t sure how well the washer nozzles would cope with hard frosts, but using 50/50 water and -10C screen wash fluid (and we’ve been down to -11c here some nights) so far fronts and rear washers have always been unfrozen and my car doesn’t have heated nozzles.
