Maruti Ciaz 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 Maruti Ciaz variants in Hyderabad. Typical estimate: ₹4,000 – ₹18,000; workshop time: 4–8 hours; coverage: 3 months, PUC pass guarantee.

Variant disclaimer: Maruti Ciaz 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.

Maruti Ciaz Variants We Check

• 1.5 K15B SHVS petrol (103 bhp)
• 1.3 DDiS diesel (90 bhp — discontinued)

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

• 1.3 DDiS diesel EGR valve heavy soot causing rough idle and check-engine light

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.
