The whole thing sits on an epoxy filled tray. You can not get to the processor. It is very water tight but it is not serviceable. All you can do is reuse the J1772 cable.
I have converted 3 units to OpenEVSE including one for Pchilds. His unit used the discontinued DIY relay unit. There is room for a P&B relay and the surface mount unit along with the GFCI coil and the LED module.
2012 Cayenne Red SL traded for:
2013 Pearl White SL Premium
Traded for a Cirrus White 2014 Mercedes B (totaled)
2016 Urano Gray eGolf SEL w/ drive assist
Loved the VW but it sat too low for my old body
Back to a Cirrus White 2017 B250E
