Do owners in urban areas like Lahore and Karachi face difficulty passing vehicle emission tests with their Changan Kalam?

Reports suggest failed fitness o r smoke tests. Is this due to malfunctioning sensors o r unregulated exhaust systems?

✅ Yes — many report failed vehicle fitness tests, especially for visible smoke and hydrocarbon levels.

Causes:

High soot output

No particulate control systems

Aging sensors and poor maintenance history

Result: Many vehicles fail emissions s required by Punjab’s Vehicle Inspection and Certification System VICS o r Sindhs environment departments.

🧾 Suggestion: Regular maintenance and possibly aftermarket EGR/DPF retrofits may be needed to comply.
