Skoda Kodiaq Catalytic Converter (2016-2024)

The Skoda Kodiaq catalytic converter is a key part of the exhaust system that reduces harmful emissions such as CO, hydrocarbons, and NOx through chemical reactions. It is often used alongside the Diesel Particulate Filter (DPF) and the Selective Catalytic Reduction (SCR) system with AdBlue injection on diesel engines. Positioned after the turbocharger and before the DPF, it oxidizes exhaust gases to neutralize pollutants and help the vehicle meet Euro 6d-TEMP emission standards.

The catalytic converter helps complete the imperfect mixture of exhaust gases by encouraging thermal reactions that neutralize excess oxygen, hydrocarbons, and carbon monoxide. On the diesel Skoda Kodiaq RS (2.0L biturbo engine), it works together with an oxidation catalyst, DPF, and SCR with AdBlue injection. For petrol engines like the 1.4 TSI, a ceramic catalytic converter certified with E9-103R or E57-103R is used. It is integrated close to the Exhaust Gas Recirculation (EGR) cooler and DPF within the exhaust system.

Common symptoms of catalytic converter issues on the Skoda Kodiaq include:

• Irregular operation and power loss caused by overheating from a lean air mixture or engine misfires.
• Limp mode activation around 2500 RPM without error codes, often due to AdBlue crystallization blocking the EGR cooler and restricting flow to the catalytic converter and DPF.
• Blinking warning lights indicating malfunctions that require immediate diagnostics to prevent further damage.

Prompt professional diagnostics are recommended to accurately identify catalytic converter faults.

The price of catalytic converters for the Skoda Kodiaq varies widely depending on the engine model and materials. For example, the 1.4 TSI petrol version uses a ceramic catalytic converter marked E9-103R and typically requires a compatible downstream oxygen sensor replacement. Replacement parts comply with strict regulations and quality standards. Cost-saving options may be available through online purchasing, but compatibility with the vehicle's onboard diagnostics system (OBD II) should always be verified. Racing replacements without catalytic converters require ECU remapping and may cause issues if not done properly.

Replacement often involves removing parts like the underbody shield, EGR cooler, AdBlue injectors, and oxygen sensors to access the catalytic converter and DPF assembly. Careful alignment using adjustable clamps is needed to avoid flow restrictions. Checking for AdBlue crystallization and verifying EGR flow helps prevent overpressure issues. For petrol engines, monitoring the air-fuel mixture supports catalytic converter longevity.

Following manufacturer installation instructions and using quality genuine parts is essential for lasting performance.

Aftermarket sport exhaust systems for the Skoda Kodiaq, such as supersprint cat-back systems, are available and designed to be compatible with the original catalytic converter, maintaining conformity with EU noise and emission regulations. Some setups allow removal of the catalytic converter for track use only, requiring ECU modifications. These systems are usually made of stainless steel and include fittings for oxygen sensors. However, such modifications may not be road-legal and could affect vehicle warranty and emissions compliance.

Krosfou offers new, high-performance catalytic converters with a 3-year warranty limited to 100,000 km of use, covering defects if installed by a professional and used according to recommended guidelines. Free returns are available within 30 days for unused, original-condition parts in Europe. Technical support, installation manuals, and expert assistance are accessible via email. Krosfou products are manufactured in Europe with TÜV SÜD certification, ensuring quality equal or superior to OEM standards.

Reliable information is available from certified garages, manufacturer technical documents, and quality part suppliers like Krosfou. Online tutorials for DPF and catalytic converter replacement on the Kodiaq exist but should complement professional diagnostics. Technical support from part manufacturers can assist with compatibility checks using VIN, sensor positioning, and failure analysis. It is recommended to avoid unverified sources and always prioritize certified products to ensure correct function and environmental compliance.
