Cupra 290 5F – Power loss from speed ~230

All right! I’ve been having the problem for a few days that my Leon will fall into a “performance hole” from around 230. You notice clearly how he takes the performance completely away. Similar to running in the limiter / into the VMAX. If then also at the tempo stand or falls off partly lightly and steadily. Otherwise I have no (traceable) errors. Performance seems to be completely normal up to the speed. No noises that would be big different now than before. No warning light is on. Unfortunately, I will not find out if an error is stored in the system until next week. Nothing can be read before. Does anyone have any idea what this could be or what is close to? Greetings and love 😉
