Hi. ive bought an audi a4 b7 quattro 2.0t and have a problem with the gearbox. 1st -> 2nd -> 3 rd gear is sweet but when it shift from 3rd -> 4th and 4 -> 5th its jerky and there is rattle noise coming from the front end when it shifts from 3rd -> 4th ->5 for few seconds and it disappear when the gear has changed completely( tried it in S mode and tiptronic mode but still the same ). Downshift is sweet. Scanned it with vagcom and no fault codes found. Ive noticed that when it preparing to shift from 3rd -> 4th i release the gas pedal then the gear change to 4th gear normal and no jerky but if i push the pedal like normal its jerky again. Dont know whats wrong with it. Could u guys please let me know whats happening with my car? Thank you so much.
