G350d short-term power limit

Hello “G” driver (m/w/d), had experienced the following situation several times and wanted to see if anyone else had that in this form. Auto G350d EZ 2018 245 HP Situation: Drive on AB, speed about 180, gas taken away wg. traffic. Speed 160, accelerator pedal kicked and no increase in speed. Also speed us. remains the same. Depends on 160 feeling as with switched on limiter. Gas removal. Tempo 140, pedal crossed. remains at 140 despite full throttle. Right track, Spe ed reduces to 100. Gas pedal to the sheet metal and see everything normal. Due to the sound background I think that the DPF has been cleaned and that has something to do with it. MB says it can be safe but they are not. No errors in the memory and also no other warning lamps. I moved the car now 28TKM and had the phenomenon about 4-5 x. Never longer than 2-3 minutes Otherwise everything is good. Does anyone know that? Greetings and beautiful rest week Werner
