Jetta with electronic throttle has no response except idle throttle.

Dear friend, according to the situation you described. Both accelerator and accelerator pedal position sensors can cause this condition. I suggest you check the plug of the throttle valve for poor contact or oxidation first. In addition, check the plug of the accelerator pedal position sensor for poor contact or oxidation. I hope my analytical ideas and solutions can help you. If you have any questions, please feel free to contact me! Wish you a happy life! Happy life! The financial resources are rolling!
