Hi. I have a 451 again for my daughter and he probably also has a defective BLS. After longer service life I don’t get out of the R Gang into the N, or first gear. Only after a little effort can he put in the first gear and then it works with switching. But I also have the problem that the first gear then crashes in… and then it switches normal. Does this also hang with the BLS, or is there another problem here?
