Understanding OBD2 in Your 1995 VW Golf

The OBD2 system in your 1995 VW Golf acts as a real-time monitoring system for your engine and emission control systems. It continuously gathers data from various sensors located throughout the vehicle, analyzing this information for any malfunctions. When an issue is detected, the system triggers the Check Engine Light on your dashboard and stores a corresponding Diagnostic Trouble Code (DTC) in its memory.
