How to Adjust Volkswagen Idle Speed (Adaptive Method of Volkswagen Idle Speed Setting)

The process of setting idle speed is actually a process in which the engine control unit learns the position of throttle dead center, and it is also a process in which the curves of throttle potentiometer and throttle control sensor are compared and learned. When set, the throttle valve will run from the fully closed state to the fully open state and move to the fully closed state. (1) The following conditions must be adaptive:-Power interruption-removing throttle control unit-replacing throttle control unit-replacing engine-replacing engine control unit (2) Basic setting conditions:-No fault in fault memory-Battery voltage not lower than 1 1.5V- Turn off all accessories-Throttle should be in idle position-Clean throttle body. 2. Select the vehicle type. 3. Select the engine system. 4. Read the fault code and clear it. 5. Select channel adjustment matching. 6. Enter a matching value of "000" to clarify the learning value. 7. Select the basic adjustment of the system. 8. When "ADPO" is displayed in the screen display area 4. K "or" adaptive normal ",when the basic setting is completed. Turn off the key and press the exit key to complete the setting. (4) If the basic settings of the control unit are interrupted or wrong, there may be the following reasons:-The control unit stores fault codes. -Throttle does not reach idle stop (carbon deposit or improper adjustment of throttle cable)-Battery voltage is too low. -The throttle control unit or line is damaged. -The throttle's stuck. -During adaptation, turn on the engine or press the accelerator pedal. -Control unit code error. Precautions for Volkswagen idle speed setting:-Fault codes "17967" and "17973" are stored in the fault memory, and the basic settings will be automatically reset after the ignition switch is turned on next time. -When there is no "adaptive operation" prompt in the fourth item of data flow, but only digital prompt, it should be suspected whether the throttle body circuit is faulty, especially to ensure that the wire plug is connected normally. -Under the normal idle setting, only the key needs to be turned on, but the engine cannot be started. However, the old Audi models need to be matched when the hot car starts. -Generally speaking, the matching value of Shanghai Volkswagen is "098", FAW-Volkswagen is "060" and the old Audi 100 is "00 1". -When "Adaptive Normal" is prompted, the electronic throttle body works normally. If the engine still doesn't work normally at this time, check other parts.
