Peugeot 306 Catalytic Converter

A catalytic converter is an essential component of the Peugeot 306's exhaust system that reduces harmful emissions. It uses a ceramic monolith coated with rare metals to convert toxic gases into less harmful substances, complying with Euro 2/3 standards depending on the model. This helps protect the environment while maintaining engine performance and fuel efficiency.

The catalytic converter type for a Peugeot 306 depends on engine, bodywork, and emission standards :

• Diesel 1.9D/TD (69-70 CV): Fits 3/5 door hatchbacks, phases 1998-2002, engines WJY/DW8B and WJZ/DW8, Euro 2 with some Euro 3 compatibility.
• Petrol 1.8 16V (110 CV): Designed for 3/5 doors, Euro 2 standard.
• Petrol 2.0i 8V/16V/S16: Suitable for models from early 90s up to 1997, including some Citroën ZX equivalents.

It is important to check the exact engine code and emission standard for precise compatibility.

Key specifications differ by engine type :

• Diesel 1.9D/TD: Length 2420-2500 mm, weight 5.2-9 kg, ceramic material certified by E-Mark and ECE/ABE.
• Petrol 1.8 16V: Length 935 mm, weight 5.82 kg.
• Petrol 2.0i: Length 930 mm, weight 4 kg, monolithic ceramic with precious metals.

All converters are made from high-quality materials constructed for durability and emission compliance.

High-quality catalytic converters ensure optimal filtering of exhaust gases, supporting engine efficiency and meeting legal emission controls. Quality products, like those made with stainless steel INOX 409 and advanced monolith coatings, provide durability and often improve vehicle performance.

• Compliance with emission standards
• Long-lasting materials
• Reduced pollutants and harmful emissions
• Improved engine power and fuel efficiency

Choosing a quality converter helps avoid frequent replacements and potential engine issues.

The price of a catalytic converter varies based on type and model, with indicative prices for new quality units generally ranging from approximately €130 to €150. Diesel 1.9D/TD converters are around €134 to €151 including VAT. Prices reflect certified quality and compliance with automotive standards.

• New parts come with warranties and guarantees
• Prices include premium materials and advanced technology

Contact professional suppliers for accurate price quotes based on your Peugeot 306’s reference and type.

Yes, modern Peugeot 306 catalytic converters are often equipped with oxygen sensors or lambda sensors placed before and after the catalytic converter. These sensors monitor exhaust gases and help the engine control unit adjust fuel mixture to optimise combustion and emissions.

Removing or bypassing the catalytic converter or its sensors can cause engine warning lights and degrade performance, so any replacement must respect proper sensor fitting positions.

• Oxygen sensor(s) monitor catalytic efficiency
• Essential for engine management and emission controls
• Ensure correct sensor mounting during replacement

Always use catalytic converters that are designed for your exact vehicle reference to maintain sensor compatibility and functionality.

High-quality Peugeot 306 catalytic converters are available direct from specialised manufacturers who offer parts made of stainless steel INOX 409 with certified emission compliance like E9-103R and TUV SUD certification. These parts come with a 3-year warranty and are new, not refurbished, ensuring premium performance and longevity.

• New parts produced according to latest 2025-grade technologies
• Certified by independent European automotive authorities
• Manufactured in Europe with strict quality controls
• Available for all main Peugeot 306 engine variants

Ordering from reliable suppliers ensures compatibility, excellent quality, and warranty protection for your vehicle.

Finding the correct catalytic converter requires referencing your Peugeot 306's engine type, power output, and emission standard :

• Diesel 1.9D/TD engine codes: WJZ (DW8), WJY (DW8B)
• Petrol 1.8 16V code: LFY/XU7JP4
• Petrol 2.0i 8V/16V/S16 engines
• OEM or aftermarket part numbers like 1705GV, 1705HP, or Walker 20571
• Check also vehicle type (3/5 door hatchback, sedan, break)

Always confirm compatibility by VIN or chassis number to ensure fitting and performance. Using the correct reference ensures quality, legal compliance, and engine safety.
