High centered it today. 451 ED 2014 model. Fortunately going pretty slow <5mph, but there was a great rut and a mound of pavement sticking up where it wasn't supposed to be. Battery box seems to be OK. Looks like, if I'm reading this right, I have a battery system coolant leak at M43/3 Coolant Pump 2 and possibly Y133/2 HV battery Coolant Pump switchover valve. Also the plastic cover that covers this stuff up has a big hole in it. I'm trying to figure out how screwed I am. Definitely no driving. Although there is a Mercedes dealer here, nearest actual Smart dealer is 120 miles - I'd have to tow. What's dripping doesn't smell like glycol, and isn't green, but it's dripping out of the pump. I do a lot of repairs, but I'm wondering how much I'm biting off here.
