Signs of a Failing Catalytic Converter in UAE
- P0420 / P0430 check engine light: Catalyst system efficiency below threshold. The most common OBD-II code for catalytic converter failure.
- Rotten egg smell from exhaust: Hydrogen sulphide smell indicates the cat is not processing sulphur compounds in the fuel.
- Reduced engine power: A blocked catalytic converter causes backpressure, significantly reducing performance.
- Rattling sound from under the car: The ceramic honeycomb matrix inside the cat can break apart, causing a rattling sound.
- Failed emissions test: UAE RTA inspections check exhaust emissions. A failed cat means a failed inspection.
Catalytic Converter Theft in UAE
Catalytic converter theft has increased in UAE due to the precious metals (platinum, palladium, rhodium) inside. Toyota Prius, Toyota Land Cruiser, and SUVs with high ground clearance are most targeted. Parking in well-lit, camera-monitored areas and fitting anti-theft cat covers (AED 300-800) can reduce the risk.
