Jerking problam Audi A3

Hard to say, most likely throttle body sensor, maybe your engine overheated.

Your best bet is to get your transmission check sound like it freezing up before it gets worse.good luck.

Have you let a younger faster driver borrow your vehicle the gearbox computor will learn the harder driving style and adjust the adaption data to suit his harder acceleration and make it jerky for you

Hi Kristopher, A shudder from the manual transmission is usually caused from a defective part in the clutch assembly. It could be caused by uneven wear of the pressure plate (clutch cover) or wear on the clutch plate boss (The center of the clutch plate with the springs or rubbers which absorb the torque when releasing the pedal) A shudder can be generated from a defective engine or gear box mount, worn CV joints or spiders or a loose bell housing. Start with the last suggestion and work backwards as the clutch replacement will require the most work. If the clutch assembly has been replaced recently, and the parts available are of the same quality we receive where I am, you will need to do the job over. Regards John

indicates water in harness connections or at the terminals of the ECM or other modules

low trans fluid check the level first.

Sounds to me like you need to take a trip to your local certified mechanic!

I had something similar happen. My check engine light never came on but i did experience the jerking between the 30 and 40 mph mark. Have your fuel injector checked to see if its dirty. Also have your fuel lines checked to see if you have water in it and have them check the transmission fluid. its possible you can be low. When I had the problem i did all 3 of these things. My car does not **** anymore. Also another problem could be your valve cover gasket.

Spark plug wires

Fuel filter or vacuum leak good place to start. Good luck and have a good day.
