Hello guys, I am very much in the training for the CE appearance because I need this for my professional change. I would not have thought that there is so much to do with it. The entire catalogue of questions of the B-training has to be mastered before you can even be tested for CE. I have already 11 years of my B appearance and you hardly believe what has changed since all that. My biggest problem is probably the postponement of the trailer. This unfortunately stands sofor t crooked. I see really black during the brewing trip. What is also not realistic for me is the function of the vacuum air brake. How exactly do you have to control these and in how far will this be queried during the test trip? Perhaps someone can give me tips regarding the return parking of the trailer. Would really have helped me!! Gruss feminine
