Hi, Smart Fortwo EQ. Usually shows 99 mile ECO range when fully charged. Has suddenly changed to only 68 miles when fully charged. Any suggestions please.
Smart Fortwo EQ showing much shorter range than usual.

Not particularly. It has been colder without the shorter range. Maybe just have to wait for the next lovely sunny day!
The number of miles on my MINI's GOM decreases when the HVAC system is turned on, then increases when the HVAC is off. However, it sounds like you have plenty of experience with your Smart in cold weather, so you know if that can affect your projected range.
What chemistry in the batteries?
My NCA, 2170 cell battery pack suffered a rapid range fall off which led to a $9k replacement. It had fallen from ~210 miles to 174 miles in a few months. I suspect a failed coolant valve "cooked" the cells leading to premature aging. My replacement is down to ~190 mile range but stable.
Sad to say but cell replacement is impractical and Tesla no longer makes 2170, NCA chemistry cells. Although some claim it is possible, a LiFePO4 replacement has too many risks for my soon seven year old car. I hope to keep it running another 2-3 years with careful attention to details.
