The range estimate has to be based on something, so past history is a good indicator.NOTE: Since I returned and charged to 80% my dash range indicator will not move much above 150 mi. So is this a tech issue perhaps requiring a reset / reboot or out putting the adjusted range with tow. Due to length of time trailer was in tow did the system auto calculate or recalibrate for trailer?
I haven't seen anybody post the rules that VW uses, and haven't cracked open the manual. My i3 estimates range based on the efficiency over last 18 miles driven.
I expect the ID.4 does something similar. It shouldn't require any intervention on your part. A system reset might cause it to predict 350 miles like many of ours did on the dealership lot.
