Anybody know where the rear Blind Spot sensor/s are on a 2016 G63? I have an error message saying 'Blind Spot Assist Inoperative'. I have done a whole heap of watercrossings on my last trip and google tells me that the sensor contacts can rust out. MB Aust want A$2500 to replace and it looks like replacement modules can be sourced on Ebay, etc. I have had a look behind the rear bumper (without taking it off) and not quite sure what I am looking for.

I believe you're looking for two boxes (1 on each side) a little bigger than a deck of cards with a single connector.
