After the Jetta cable throttle was cleaned, the idle speed fluctuated and the engine speed could not come down.

According to my experience in teaching in the unit (North School) and repairing cars in the maintenance station, I tell you that all models of Volkswagen Audi, whether direct-acting or electronic, need to be equipped with instruments in the following situations.

1, as long as the throttle body is disassembled; 2. The throttle control unit has been replaced with a new one; 3. The engine control unit has been replaced; 4. Adjust the throttle cable; 5. When cleaning the throttle body, throttle matching is required.

Thank you. Satisfied, please adopt.
