Have the problem that since we have our Laguna 3 Grandtour the parking brake flashes permanently. I only noticed this because I have watched some videos regarding the brakes. On the display there is no message. Self test always without finding out. Error reading also did not result. The first car without any error. No matter if parking brake is attracted or not, the thing always flashes. Does anyone have an idea? Can only read out errors at the moment. More unfortunately not yet
