Problem with reverse – Macan GTS

Moin together, I have the following problem: When I put in the reverse gear and then take the foot off the brake, it takes felt 2-3 seconds until the Macan reacts with movement also the gas acceptance finds only delayed satisfied. If I stand down, it rolls even with inserted reverse gear forward. Two times introducing the service did not bring anything. It was refilled only once gear oil – but without any effect. You can’t recreate the phenomenon… H someone here has ever had something similar? Many greetings, Helge
