No taxi no foot light no radio and temp gauge pegged with its light on

 

I ran my battery down by leaving my ODB-II reader plugged in. Put battery on trickle charger and would up doing the same thing - no turn signals, headlights wouldn't turn off, all other electrical stuff freaked out.

Turns out my footwell monitor went out and had to be replaced (twice actually, the first one they put in wouldn't program). Luckily there was an extension of the warranty for it on mine (2010 R57) so I have no clue how much it would've been out of pocket.
