Are Pakistani Changan dealerships and workshops checking emission systems EGR, sensors, catalytic converter during regular maintenance of Karvaan?

Many emission-related components are ignored in service routines. Should a standard emissions check be included in every major service?

Yes:

EGR valves, O2 sensors, and catalytic converters are often not inspected during routine servicing.

Workshops focus mainly on oil, brakes, and filters, ignoring the emissions system unless a check engine light appears.

No standardized emissions checklist is used by most Changan dealerships in Pakistan.

⛔ Conclusion: Emissions systems are poorly monitored, and a mandatory emissions health check should be part of every major service.
