The last few mornings have been very wet and the ambient temp has dropped a lot !.
Our car sits on the drive and has no protection from the bad weather.
I have found the pre-heat facility on the App for the HVAC to be a real god send to be honest.
If find if I run a health check first ( allowing the App to communicate with the car first ) then request the A/C ( Pre-heat in the cabin ) it works almost every single time, straight off !.
If I request the A/C straight away with out running the heath check, it tends to some times fails with the request.
I find having his feature a huge benefit over the Gen 1 model.
