500e electrical system issue

[iAmReitman]

I've been lurking here for a while, but now I'm officially asking for help. My 500e is giving me a ton of trouble. I drove it normally, parked it overnight, and the next morning, the dashboard was a mess with all kinds of electrical faults. I've tried everything I could find online - replacing the 12V battery, resetting the HV and LV batteries, disconnecting the humidity sensor, and even towing it to a shop. But nothing seems to be working.

I'm about to buy an Android tablet and an AlfaOBD to read any codes. Does anyone have any other suggestions or advice?

Go ahead and purchase your tablet along with the Alfa software, and don’t forget the BT dongle or OBD link cable. Once you’ve got all that, your next step is to clear out those pesky faults.
