Hello everybody, I’m not lucky lately, but maybe someone can help me before I have to go to the workshop. On Saturday in my Golf Cabrio 1.6 Tdi EZ 07/11 a heater was retrofitted in the Webasto specialist company. Now the following situations arose: On Saturday I drove home from the workshop (about 1 hour driving time) I then parked the car. The next day I didn’t have to leave, but wanted to try the heater, o b it works with the Thermo Call, they have set only 15 minutes. I then sat in my car after the end of the time, started it normally and also ran, then drove backwards out of the parking space and then suddenly he washed out. One start no longer possible, only a gurgled, but did not jump on. He had disturbed me the symbols for catalyst and generator. Had then light radio etc. everything exhibited and he then jumped after a few times ve I then drove about 45 minutes through the area, then turned it off, this time backwards into the parking space. left it then about 1 hour and then let the heater run for 25 minutes. Down into the car, start without problems and go off also. I then drove again about 45 minutes by car and then put it off. This morning I ran the heater then about 30 minutes. Then start down to the car, again without problems, at the back drive again baff car off and again the 2 symbols displayed. Again trying to start no chance, also not in the first gear. Also not with switched off consumers he has jumped. Now the car stands there, I can not get away anymore, he does not start, he gurgles only, even the attempt if you notice that he then comes to give gas does not work. Is it somehow possible that the stationary heating sucks the battery over night empty, because when he stood only the 1 hour it went. With the It can’t have anything to do with driving backwards. I’m confused now that he’s never had that before, only since the heating has been installed. I’m in despair right now. Or does my car somehow not understand that it’s warm, but the rest isn’t yet? Is there some kind of update? Maybe one of you can help me…
