Hello, I received such an error code with my GLX Benzin Hybrid (BJ 21) at TÜV P12EB 12 (recurring). TÜV did not pass because no HU was possible. In Polish Opel workshop in Grünberg, I read out with elaborate test of the whole car (translation): “Short circuit (+) in electric circuit of the liquid temperature sensor in the cooling system of the DC charger / rectifier assembly group.” I called Freundlichen in Frankfurt (Oder), in Poland (Grünberg, Landesberg) whether di ese sensor (temperature filler) is to be replaced. ALL have told me, since? not even catalog number for this part gives and you have to replace whole charger. So are the procedures at Opel. Cost point 7000 PLN ( 1600 €!!!) plus labor costs (about 8 h). I have called specialist in Gdansk from the hybrid – car in Gdansk (several branch in Poland, next for me would be in Poznan) and he immediately said that 99,9% could be a seal in liquid pump defective and thus liquid k My friend asked Opel mechanics in Opoles. They said that there should be a known factory error and to eliminate that costs me 5000 PLN (1100 €). But total cost 17 000 PLN!! The difference comes directly from the Opel Poland. And now becomes interesting: for over 3 years, I regularly load the car from the socket and everything is okay. Fully charged and even recuperation works! What do you say? Already had such a problem? And how solved could this be? t? Ingewelchen Idee? Thanks and sorry for grammatical errors. Maszynista
