I try to turn heating on when car was plugged in but blowing only cold air....
Richi I could do with some of your advice regarding heating.The heating will not work in ACC or ACC2 mode (and you will flatten the 12V auxiliary battery trying).
You either need to be showing the green READY symbol, which you can't do when plugged in, or use the timed heating control—via the MMCS or Remote app.
Ok done that nice and toasty, I am going out on Sunday on a 70 mile journey, I will turn the heating up to 24 and see how it goes, thanks for your help I am still in that steep learning curve. Thanks to your help I ahave now got the towing down to a fine art.Heating shouldn't be poor. My 2014 gets roasting, with or without the engine.
As a diagnosis step, if you run the preheat for 10 minutes, does the car get nice and toasty? (Easiest way is via the Remote app, but the alternative is setting a timed preheat.) Don't forget to select heat, rather than cool 😷
