Hello, how to read I am to upgrade to HP2 brake when thinking about the models from 91 or Fhrgtl No. 4CNN004001. This should be possible without much effort. Unfortunately, I don’t know how the number reads… Mine starts with WAUZZZ4C……3298 ? It’s always AB of this number. Does mine come in now? because the UFO is simply not what makes me happy, should the values of the HP2 be only slightly better the effort for me would have already invested … Maybe someone can help me… Greeting KW200
