This guide will walk you through how to use a VAG COM diagnostic cable to reset the service reminder on your Audi A4 B8, empowering you to take control of your car’s maintenance.

What is a VAG COM and Why Do I Need It?

VAG COM, also known as VCDS (VAG-COM Diagnostic System), is a powerful diagnostic tool that allows you to communicate with your Audi’s onboard computer. This tool provides a wealth of information about your car’s systems and allows you to perform various tasks, including resetting the service light.

How to Reset Your Audi A4 B8 Service Light Using VAG COM

Before you begin, ensure you have the following:

• A laptop with the VAG COM software installed
• A compatible VAG COM cable
• Your Audi A4 B8

Step 1: Connect Your VAG COM

Locate the OBD-II port on your Audi A4 B8. It is usually found under the dashboard on the driver’s side. Connect the VAG COM cable to the port and your laptop.

Step 2: Launch the Software

Turn on your car’s ignition (do not start the engine). Launch the VAG COM software on your laptop and select the “Select Control Module” option.

Step 3: Access Instrument Cluster

From the list of control modules, select “17-Instruments.”

Step 4: Select “Adaptation”

Click on the “Adaptation – 10” button located in the top menu bar.

Step 5: Choose Service Reset Channel

A new window will open. In the “Channel” drop-down menu, select the appropriate channel for your specific Audi A4 B8 model and service interval. Refer to your owner’s manual or the VAG COM documentation for the correct channel number.

Step 6: Reset the Service Interval

Once you have selected the correct channel, click on the “Read” button. The current value of the service interval will be displayed. To reset the service interval, click on the “Save” button.

Step 7: Confirm Reset

The VAG COM software will prompt you to confirm the reset. Double-check that you have chosen the correct adaptation channel and click “Yes” to confirm.

Step 8: Verify and Exit

After the reset is complete, verify that the service reminder on your dashboard has been cleared. You can now disconnect the VAG COM cable and turn off the ignition.

Expert Insight from John Miller, Senior Automotive Technician: “Always double-check the adaptation channel you are selecting in VAG COM before performing a service reset. Selecting the wrong channel could potentially lead to unintended consequences. When in doubt, consult your owner’s manual or seek guidance from a qualified technician.”
