If one is shopping for a used 2016 VW SE, is there any outward/exterior way to know if the SCE has the optional 7.2kW charger? I have a 2015 version, and all of the cars came with a 7.2kW onboard charger. My understanding is that in 2016, VW went with a 3.3kW charger as standard with the SE's with 7.2kW as an option.
