Moin Leutz and Happy Easter for now, someone from you has a tip, where I find a tip for acoustic feedback when closing the vehicle? Here you can not make such a thing public, we are after all all all good subjects here, which of course ALWAYS adhere to ALL applicable rules … Therefore I ask in the sense of secrecy to pass all suggestions ONLY by PN to me, in the hope that PN is also P… Thank you for the support ng Ralle
