P0420-style efficiency codes are common, but not every one means a new catalytic converter. Al Sadiq Garage tests upstream issues — misfires, oil burning and sensor faults — that poison catalysts on cars driven hard between RAK and Dubai.
Rattling converters indicate broken substrate that can clog the exhaust and kill power. We confirm restriction before recommending replacement with quality units suited to UAE fuel.
Honest diagnosis protects you from unnecessary converter costs while keeping emissions systems healthy for long-term ownership.
