checked on internet, and my bridged pins are PP (not CP) with PE. TOP LEFT PIN when you look at the charge connection in the car to the center one.
The right side of the picture shows the male plug of the car (mirrored). The roadside assistance connected my PP (control pilot) pin with the PE protective earth pin. The PP is pre insertion signal, so, if this is neutralised by connecting to earth (pe) the car will think no cable connected i assume, so makes sense to bypass the car logic/error.
