ABEFluenceZE

Hello, from Spain. I think i've got the same simptoms in my Fluence ZE.....l'affichage suivant sur le tableau de bord: système électrique à controler. The car is OK, 11600km alwais smooth. This happens two weks ago. In renault they say is necesary to change the engine (rotor and transmisión box), but i think this is ok and the problem seems a bad connection samewhere. So, id like to know how you repair yoorself this problem or message, exactly which cable or connection has oxyde, because i dont want they change the engine althoug is in warantie. I am worried they touch my car, because they never unmount or mount any ze engine (the mechanic told me). If you could attach any photo of cable or connection......thanks a lot.
