Hello municipality, if the distance warning warns (what else should he do :-)) then I have a funny noise from the dashboard from time to time, similar to when you hit a book. It also reminds of a pumping noise. I have the same – also from time to time – when I wear the ACC and the car slows down. Then it is in fact rather in knocking or pumping. But starting from the same place of the dashboard. I can remember that a user (I believe Zottel125) meant, so a sound could be any part of the braking system (I didn’t notice which one) and that he’s seen the thing that breaks this part before. Question: Is that so normal? Or off to the service? VG
