Hello, have bought my Ibiza 12V Stella 2 months ago with almost 150tkm. TÜV was made in July 2012, and I recently had the brake pads changed, because it was on the defect list of TÜV. Up to now I am with the car almost 300km danger. I have a small problem, which is why I worry. And that is that the car vibrates when I turn up, and speed up with these revolutions. it is as if the cockpit is vibrating. At the beginning I thought that would be normal. But I It’s like I’m going under-touring, but these turns aren’t under-touring. All of them switch to drive sprite-saving at 50km/h into the 4th gear. If I do that, the car vibrates as if it were going under-touring. I’m not going under-touring at 1800 revolutions. It’s only at 55-60 km/h that he drives quietly. In the first gear he drives cleanly, even if I pull up to 2.5k revolutions! At the moment I’ve got At 20km/h I switch to the 2nd, at 40km/h in the 3rd and at 60km/h in the 4th. And from 70km/h I can switch to the 5th, and he drives clean. Is that normal, my brother has a 1.6l Alfa Romeo 147, and he then switches to the 4th at 50 to save sprite. The car drives completely calmly. When I do this, the cockpit vibrates. The car is neatly stocked, and was always on every inspection. Thank you in advance!
