Repairing a BMS "glitch" on a 2019 Smart EQ

Howdy folks! In this video, we get to work pulling the battery out of this 2019 Smart ForTwo EQ in order to remove the BMS and send it off for to have the contactor cycle counter reset. The contactor counter getting glitched to 0 cycles remaining is a "known issue" for these cars when a digital logbook/mileage tracker is used. As far as Mercedes is concerned, when something like this happens, none of the batteries internal components are considered serviceable, so the entire assembly needs to be replaced (yes, even for a simple software glitch, or even if the contactors really were in need of replacement). Unfortunately for this customer, Mercedes denied the warranty claim for the battery as it hadn't had it's bi-yearly desiccant cartridge changes performed, leaving them on the hook for an $18k repair bill to replace the pack. Luckily, I was able to track down a vendor who could reset the contactor counter on the BMS (albeit all the way in Germany), and get this car back on the road for MUCH cheaper.
