Hello everyone, I don’t look through that anymore. when I bought this car two weeks ago I stayed on the motorway because of an alternator damage. that was near Kassel and I had to go to Hamburg. In Kassel an exchange alternator was installed. After installation of the alternator we found that the control light is still shining, but the battery was charged, well, so I came to Hamburg and after a few days the same as on the highway, I stayed there again this time I thought it was all just because of the battery so and therefore the control light was lit. I first went off and bought me a battery with the hope that the control light finally disappeared, but negative. After that I drove to the car self-help to peek what is really going on. And tataaa there was, the idiots in Kassel have connected the connection to D+ line wrongly, before joy I have you again properly screwed on battery again clamped, engine started, but without success the charging control light continued to glow!!! Now I am really desperate and don’t know any more. for the replacement alternator I flipped exactly 250€ in Kassel. Here costs a new exactly 313€ And the Austaus alternator I can no longer give back, since it should have no guarantee 🙁 ! at the moment the car runs because it has got a new battery but does not know to where d he would suffice 🙁 my question to you: – is maybe also the replacement alternator defective? – is perhaps still where else a mistake? – did someone else have the same problem? for your help I am very grateful MfG
