My dealer did the H228 Enhancement Program last week. When my vehicle left the dealer shop after this work the range showed as 279 miles at 100%. It was driven 116 miles to my home and the range had dropped to 80 miles. That was a trip of 116 miles and a drop in range of 199 miles. Since then I have driven several short distance trips at low speed in Eco mode with full brake regen and charged to 100 three times on my home Juicebox. Each one of these charges has only resulted in a 100% range of 201 miles. I have owned my 2019 First Edition for 4 months and never achieved the JLR claimed 235 range but prior to getting all the software updates I was consistently getting 210 miles range. After all the updates it seems that my range has dropped to 201. I have tried the reset as explained by the dealer but this makes no difference. I am currently waiting for a return call from the dealer on what happens next.
