GPF lamp, increased consumption and poor engine run (3.3l)

I had an interesting experience earlier. When I was speeding through the highway there was a short jerk, which I thought was first for switching up. Then I noticed from 200 off that a little power was missing, so roughly 100hp, and a yellow lamp glows, which looks a little like steam ironing. I thought that this was probably some lamp from the particle filter. After that the jerk was reproducible when accelerating through at about 4000 revolutions, at least on the Highway. On the next occasion I stopped for a short time to verify my guess regarding the importance of the lamp with the manual, but did not turn off the ignition. I was already off the highway anyway, on the way home and then drove the rest of the country road in sports, so that it remains over 1500 revolutions. I noticed that the engine developed a quite pronounced partial trucking and developed a quite considerable thirst In sport at around 2000 turns with Tacho 56 he wanted about 20l/100km. Whether the performance was still full is hard to say, but he still felt attracted to normal. I had already agreed that probably to have to address during the inspection next week, but wanted to check the oil level one way or another. So at the gas station around the corner stopped and checked, then ignition completely switched off. Oil level was ok. After starting the GPF-L ampe away, the motor run normal and the consumption at constant drive in the inner place again normal. I’m curious if that happens again or if the good only swallowed up. Has anyone ever experienced something similar?
