I am into my 37 month of a lease -- 2015 egolf SEL. I have not subscribed to car-net beyond the free offering. There are seven sub-categories for the car-net web app -- status, remote, boundaries, speed, destinations, vehicle health, and trips. I can still access status, remote, and trips without an additional subscription. For the other categories a message states that I must subscribe. Since my utility does not offer lower off-peak rates, I have not programed charging schedules. I have used the app only to limit the charging current to 13Amps in the battery sub-category. At the 36 month anniversary, I changed the charging current to MAX since I do not know what control I will have going forward and I can still control current via my EVSE.
It is my opinion that both VW and egolf owners would benefit if car-net was extended without a subscription charge. Their dealers would benefit from service from negative vehicle health reports alone! Additionally, VW is still gathering data as the obvious and hidden status numbers are transmitted back to VW. So, owners should be compensated for their contribution to the data steam.
