Here are the options and considerations for dealing with catalytic converter issues:

Cleaning:

Pros: Can remove minor deposits and improve performance temporarily.

Cons: Not always effective for severe clogging o r physical damage results may be short-lived.

Repair:

Repairing catalytic converters is generally not practical because the catalyst material is integral and cannot be easily fixed.

Replacement:

Pros: Provides a long-term solution, restores performance and emissions compliance.

Cons: OEM catalytic converters are expensive and may take time to source in Pakistan. Aftermarket options are cheaper but vary in quality.

Recommendation: For a Mercedes-Benz S-Class, replacing the catalytic converter with a genuine OEM part o r a high-quality aftermarket unit is usually the best choice to ensure reliability and maintain emission standards.

Costs in Pakistan can range from moderate to high depending on parts and labor, so sourcing parts from trusted suppliers and working with experienced mechanics is crucial.
