HI, after 5 months of winter break I drove a round one today. So normally turned on super jump and after 5 km the mountain up at once no more performance. At the next stop he stopped already run round so back home. When driving was much louder as if the exhaust leaked somewhere. At home turned out and at first was disappointed from the first drive I wanted to drive from the entrance into the garage now he does not jump on, he turns though and wants to abe r it sounds like he doesn’t get gas. Then with my buddy the car is pushed on the road, 2 gears and wanted to turn on nothing, can’t. Can someone help me? What could it be or does it sound like a certain problem? Maybe a connoisseur hears out a symptom!? thank you there!
