The old-fashioned system to begin a arctic machine engine is to plug a charger into the wall and then connect the charger to an ignition plug. On the other hand dissimilar technologies such as VAG-COM concede you to flame the glow plug using controls from your laptop. VAG-COM is a third-party car diagnostic software from Microsoft that is compatible with several models of Volkswagen passenger cars. The software diagnoses several problems, including ignition issues. The default settings on VAG-COM keep the ignition plug glow time to a minimum; however, in extremely cold weather, you may need to extend the glow time to charge the car battery. The newer version of VAG-COM is called VCDS (VAG-COM Diagnostic System).
Instructions
1. Make sure it's not a chronic case of being unable to start your car with the initial voltage. If you have frequent cold start problems, extending the glow time won't remedy a more serious underlying issue. Typically, you'll have to extend the glow time for a car resting in very cold weather or at higher altitudes.
2. Connect to VAG-COM. First, you should have the VAG-COM diagnostic software installed on your laptop. You should also have a USB cable (1.1 or 1.2) to connect from your laptop to your car. Plug one end of the cable into your laptop and the other into a plug located below the dashboard on the driver's end of the car.
3. Turn on the car ignition key. Once you turn on the key, the VAG-COM controller window should appear on your laptop screen.
4. Log in to the VAG-COM controller. You should have a five-digit code to log in.
5. Click on "Adapter" and go to "group 12."
6. Change the adapter value. Change the value to bring it closer but never below 32700.7. Turn off the ignition key and turn it back on. Go back to the adapter dialog box. In the adapter controller dialog box, there are two values you should keep an eye on. First, make a note of the value registered in the box titled "no. of units," which represents the glow time. The default value is usually between one and two seconds. Second, you should find a text box with the title "new value." The default value in the "new value" box will be 32768.
The value for "no. of units" should now be higher than the previous value. Keep lowering the adapter or "new value" closer but never below 32700 to extend the glow time. Typically, an ignition plug glow time of three seconds is sufficient to start a car.
