Hello, my vehicle is 2015 model 1.2 Puretech Eat6 130 HP Allure. At 47,000 kilometers. I love my vehicle, but a problem started to bother. When I kick down with my vehicle, I don't have any problems when it drops 1 gear, but when it drops 2 gears in aggressive kick down to accelerate suddenly, the vehicle jolts and shakes. Today I took my vehicle to Göral. They examined the error codes, but there was no record of any error in the brain. As you can imagine, there was a conversation about buying gasoline from opet or shelld. If you are looking for fever in Ankara - Çankaya, you will not find dirty poor quality gasoline anyway. Which I am almost sure is not about gasoline. My vehicle was accelerating like a poem a month ago under the same conditions. I am open to the ideas of friends who can give ideas. I can think of fuel filter, spark plug, fuel tank, throttle etc. Or god forbid the gearbox is coming. Thanks in advance.
