What causes the warning light to illuminate in the Volkswagen Lavida?

Reasons for the warning light illumination in the Volkswagen Lavida: 1. Abnormal engine oxygen sensor; 2. Clogged fuel injector and carbon buildup on the intake valve; 3. False fault phenomenon. The Lavida is a sedan under Shanghai Volkswagen, with exterior dimensions of 4605mm in length, 1765mm in width, and 1460mm in height, and a wheelbase of 2610mm. The car features teardrop-shaped headlights, a U-shaped front grille design, and inherits the traditional Volkswagen family grille. The rear design of the Lavida is relatively compact, with a chrome strip connecting the taillight clusters to form a cohesive whole.
Last time the fault light on my Volkswagen Lavida came on, and I was really a bit panicked. As a veteran driver with ten years of experience driving this model, I immediately pulled over to a safe spot, popped the hood to check, and found no oil leaks or loose wires. I took out my OBD scanner and connected it to the diagnostic port, which showed an engine management system fault code P0420, possibly related to the catalytic converter or oxygen sensor. Later, I drove to the repair shop, and the technician confirmed after inspection that the oxygen sensor was aging and needed replacement. After replacing it, everything was fine. This experience taught me the importance of regular maintenance, such as checking the exhaust system and changing the oil every six months to prevent such issues. The Volkswagen Lavida is a compact car, and its emission control system is prone to minor problems, so I recommend addressing them promptly rather than delaying. Before stopping, I also checked other indicator lights on the dashboard to ensure it wasn't a safety-related fault, which gave me peace of mind while driving.
