2020 VOLKSWAGEN JETTA with 6000.0 miles

The epc light comes on randomly at highway speeds when revving up the engine to overtake cars. The engine suddenly bogs down and engine rpms are limited to 3000 when light is on. It could be a potentially dangerous situation because the car will not want to accelerate and forces me to get off the freeway. The only way for the light to come off is to turn off the car and turn it back on. I visited a local vw dealer and they informed me of a fault code P227900 intake air system leak passive/sporadic. They performed an air intake system test and found no problems. This is the third time this epc light comes on. If it happens a 4th time i will once again take it to the dealer if something comes on. It is very frustrating that i can't rev my car at highway speeds or else this light keeps turning on.
