Why does the service belt come off the pulleys in the BMW X3?
Years 2010-2017

Answer

The reasons why the compressor belt of the BMW X3 often falls off the pulleys can be different. For example, the problem could concern the belt itself, by now too worn and no longer elastic, or it could concern one of the two pulleys. In the latter case, we will have to make sure that they are aligned and that they rotate perfectly in axis. If not, we will have to proceed with the replacement of the damaged item.
