Understanding Diagnostic Trouble Codes (DTCs)

What Causes DTCs?

A variety of issues can trigger DTCs, ranging from minor sensor glitches to more serious mechanical problems. Common causes include faulty sensors, wiring issues, and mechanical failures.

Connecting VCDS to Your Jetta

Before you can clear any codes, you need to establish a connection between your VCDS interface and your Jetta’s onboard diagnostic port (OBD-II port). This port is typically located under the dashboard on the driver’s side. Ensure your ignition is turned on before connecting the VCDS cable.
