MG Hector Catalytic Converter Cleaning in Hyderabad | GarageNation

GarageNation assesses in-situ or bench chemical cleaning of catalytic converter to restore emission performance and PUC pass for compatible MG Hector variants in Hyderabad. Typical estimate: ₹4,000 – ₹18,000; workshop time: 4–8 hours; coverage: 3 months, PUC pass guarantee.

Variant disclaimer: MG Hector has multiple engines and transmissions. This page is not a claim that every variant uses this component; we confirm VIN, engine/transmission data and diagnostic results before approving work.

MG Hector Variants We Check

• 1.5 TC petrol (141 bhp)
• 1.5 TC petrol + 48V mild hybrid (141 bhp)
• 2.0 FCA diesel (168 bhp)

Symptoms That Merit a Check

• PUC emission test failure — CO or HC above permissible limits
• P0420 or P0430 fault code — catalyst efficiency below threshold
• Rotten egg (sulphur) smell from exhaust suggesting converter saturation
• Poor fuel efficiency from exhaust backpressure from a blocked converter
• Engine running hotter than normal from restricted exhaust flow

Diagnostic Process

• OBD2 scan for O2 sensor data — upstream vs downstream voltage pattern reveals catalyst efficiency
• Exhaust back-pressure test across catalyst to quantify blockage
• Catalyst temperature test — underperforming catalyst runs cooler than specification
• Rich-running root cause investigation before cleaning to prevent recontamination

Model Context and Repair Decision

The model data does not identify a recurring catalytic converter cleaning fault for every MG Hector. Diagnosis therefore starts with the reported symptoms, fault codes and measured values rather than an assumed model weakness.

Repair is considered where testing confirms a serviceable component and safe parts availability. Replacement is recommended only for confirmed wear, damage or a failed test. A written estimate follows diagnosis; no work starts without approval.
