iX xDrive40 Real World Range

I’m also suffering from poor range. Based in the UK with temps around 5-10c, I cannot get above 1.5m/kw. On a full charge car is showing I have 175 miles but only manage to get 120-130 out of it. I have a car with 22” wheels and full tech pack. Mostly drive in B mode in the city. This range does not make sense. My i3s was much better. i just got the car back from service after a recall update. I asked BMW to check the car. They claim nothing wrong with the car and suggested I pre condition the car every morning. After speaking directly to the technician, he told me that he has noticed that the m40’s drain a lot faster than the m50’s but can’t work out why. Anyone else getting really poor range?
