Dacia Sandero Catalytic Converter

The catalytic converter is a crucial component of the Dacia Sandero's exhaust system. It transforms harmful exhaust gases into less polluting emissions through a chemical process called catalysis. This reduces the environmental impact of the vehicle by filtering and converting toxic gases before they exit the exhaust.

The catalytic converter works best at temperatures over 400 degrees Celsius. During cold starts or short trips, its efficiency is limited. Modern Dacia Sandero models typically have two catalytic converters: a pre-catalytic converter situated between the exhaust manifold and the main system to pre-filter gases, and a main catalytic converter that performs the primary conversion of exhaust gases.

The catalytic converters for Dacia Sandero vary by engine type and emission standard compliance as shown in the table below:

• 1.2 16v (75 hp / 55 kW) - Motorcode D4F732 - Euro 4/5 - €235,00
• 1.4i (75 hp / 55 kW) - Motorcode K7J710 - Euro 4 - €245,00
• 1.6 8v (82-84 hp / 60-62 kW) - Motorcode K7M818 - Euro 5 - €340,00
• 1.6 MPI (84 hp / 62 kW) - Motorcode K7M800 - Euro 5 - €340,00
• 1.6i (87 hp / 64 kW) - Motorcode K7M710 - Euro 4 - €245,00
• Sandero II 1.6 8v (83 hp / 61 kW) - Motorcode K7M812 - Euro 5 - €340,00
• Sandero II TCe 90 (90 hp / 66 kW) - Motorcode H4B408 - Euro 6 - €330,00
• StepWay 1.6i (87 hp / 64 kW) - Motorcode K7M710 - Euro 4 - €245,00

Choose the catalytic converter matched to your Dacia Sandero’s engine and emission standards for optimal performance and compliance.

Modern catalytic converters for Dacia Sandero are constructed using advanced stainless steel (INOX 409) and high-quality ceramic monoliths with honeycomb structures. These materials provide exceptional durability and play a key role in effectively reducing exhaust emissions.

The general replacement procedure involves:

• Disconnecting oxygen sensor connectors (primary and secondary sensors).
• Removing bolts fixing the catalytic converter to the exhaust manifold and engine block.
• Carefully removing the used catalytic converter.
• Installing the new catalytic converter with new gaskets.
• Tightening the engine support bolts to a torque of 25 to 28 Nm.
• Reconnecting the oxygen sensor connectors.
• Ensuring final tightening of all mounting bolts.

Professional installation or detailed tutorials can help ensure correct replacement and optimal performance.

The catalytic converter warning light on the dashboard indicates that the system detecting exhaust emissions has found an issue. This could mean the catalytic converter is failing or is not functioning efficiently. Common causes include:

• Clogged or damaged catalytic converter.
• Faulty oxygen sensors (Lambda sensors).
• Leaks or damage in the exhaust system.
• Engine running issues causing improper emissions.

When this light appears, have your vehicle inspected promptly by a professional to diagnose and resolve the issue. Delayed action may lead to increased emissions and engine problems.

Yes, catalytic converters can sometimes be cleaned to remove deposits or minor clogging. Cleaning methods include using specialized fuel additives, professional ultrasonic cleaning, or specific mechanical cleaning procedures. However, if the catalytic converter is severely damaged or worn out, replacement is recommended.

• Cleaning can improve exhaust flow and reduce warning light issues.
• Do not attempt cleaning if the catalytic converter shows physical damage.
• Always consult a professional before attempting catalytic converter cleaning to avoid causing further damage.

Regular maintenance, appropriate driving to reach operating temperature, and timely engine repairs help prolong catalytic converter life.
