Hello in the round I have been owner of a Skoda Yeti 2 liter diesel 4×4 140 hp built in 2009. The vehicle is rolling in sliding mode about 1300-1500 revolutions, 3 gear 34-38 km/h, road is going off slightly mountain. When accelerating in 1 gear there is a short power drop at about 2100 revolutions. That’s what it does sporadically in warm and cold condition. Was already several times at the Skoda dealer. Softwarupdat was made last year in December. Another Skoda workshop had AGR valve and throttle valve were connected to the plant. The drop-out at 2100 revolutions is gone, only the jerking still does not appear when I am in the workshop. Since I bought the car they only tell me a bullshit like something about air pressure etc, so would be normal. If someone has the same problem or can help me. PS. Had a yeti before that did not make all this. Greetings Dirk
