Some Audi A3 owners report experiencing jerking during acceleration, even after replacing motor mounts, which may be attributed to various underlying issues. Commonly, a misfire can cause the vehicle to jerk when pressing the accelerator. Additionally, problems with the transmission, such as jerky gear shifts, can also lead to similar symptoms while driving. Owners may notice hesitation or jolting when pressing the gas pedal, indicating potential fuel delivery or engine performance issues. Furthermore, jerking, surging, or stuttering during acceleration may suggest complications with fuel filters, fuel injectors, or spark plugs. To resolve these concerns, it is advisable to check and replace clogged air or fuel filters, clean or replace malfunctioning fuel injectors, and swap out old spark plugs. If these measures do not alleviate the problem, seeking professional assistance for further diagnosis and repair related to the transmission may be necessary.
