How to diagnose an error?
There are two options for checking a Volkswagen car for errors – a computer check and an ignition self-diagnosis.
IMPORTANT TO KNOW
Instead of a computer, you can diagnose a car with a phone; you must first install the appropriate program on your mobile gadget.
Testing using a laptop or smartphone is done as follows:
- A wire with an adapter is connected to the OBD2 connector. The other end of the cable must be connected to the USB output of the computer. If you are using a phone, you must establish a wireless Bluetooth connection.
- A verification program starts on the computer.
- The test starts. The utility should check all components and display Volkswagen error codes on the screen. Depending on the program, the user can specify individual systems for diagnosis.
- The resulting combinations of problems are deciphered, after which the car is repaired.
Self-diagnosis is performed as follows:
- The heating unit in the car is turned off, after which the ignition system is deactivated.
- The user simultaneously presses the fan economy and air recirculation buttons. These controls must be held for three seconds.
- The ignition is activated, the keys are not released. The vehicle control unit will turn on the self-diagnosis mode, as a result of which the fan will automatically operate at each power level. A fault combination should appear on the display located on the dashboard.
- To move to the next error code, use the heater air temperature increase button. If the combination 000 appears on the screen, this indicates that the list of faults has been completed.
How to reset the error Volkswagen?
GOOD TO KNOW
It is necessary to reset the combinations after all the faults have been eliminated. Erasing the codes without eliminating the errors will result in the problem remaining, but the information about it will be deleted from the control unit’s memory.
To display combinations after self-diagnosis, perform the following steps:
- After reading the errors, press the heating unit’s economy mode button. Hold the button down for three seconds.
- If the combinations are deleted, the code 444 will appear on the screen.
- The economy mode button is pressed again to leave the self-diagnosis menu.
If a tester was used for testing, removal is done as follows:
- After reading the codes, the ignition in the car is turned off. There is no need to disconnect the wires from the scanner or adapter.
- Press the contact closure key on the device.
- The ignition is activated. After 5 seconds, the contact elements open.
- The ignition in the car is turned off. All fault combinations will be deleted from the memory.
