Audi A1 Catalytic Converter 1 (I) (2010-2018)

The catalytic converter for the Audi A1 1.0 TFSI (chassis 8X1/8XK with engine codes CHZE or CHZB) is an essential exhaust component designed for petrol vehicles compliant with Euro 6 emission standards. It fits models produced between 2015 and 2018 with engine power options of 82 hp (60 kW) or 95 hp (70 kW), 999 cc, 3-cylinder, 12-valve engines. It reduces harmful emissions such as hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx), ensuring compliance with environmental and technical regulations.

Key Original Equipment (OE) references include: 6C0254501LX, 6C0254501MX, 6C0254502AX, 6C0254502S, 6C0254502SX, 6C0254502T, 6C0254502TX, and 6C0254502X. Main technical details are:

• Euronorm compliance: Euro 6, tested under UN-ECE Regulation No.103 Rev.1 + Amend.1 (June 2014)
• Approval: E-mark homologation permitting road use without extra inspection or return of old catalytic converter
• Dimensions: approximately 650 mm length
• Weight: around 4.85 kg (example from A1 Sportback 8XA/8XK)
• Compatibility: Manual gearbox vehicles, delivered with installation kit including screws and gaskets
• Warranty: 24 months legal guarantee
• Function: Reduce exhaust pollutant emissions meeting technical control and manufacturer standards

Before purchasing, ensure you verify key details to match your vehicle’s specifications:

• Confirm the Euro standard and engine code (CHZE or CHZB) of your Audi A1 1.0 TFSI
• Check that the reference number of the catalytic converter matches your vehicle’s original equipment
• Ensure the product comes with proper European homologation (E-mark) and installation kit
• Consider warranty and aftersales support offered by the manufacturer or supplier
• Review installation instructions and compatibility with your car’s exhaust system

For precise search and product details, use trusted online networks and filters by power, year, and engine type. Always avoid ethanol or flex-fuel catalytic converters for this petrol engine to maintain performance.

Delivery time for Audi A1 1.0 TFSI catalytic converters typically ranges from 5 to 8 working days, with options for immediate shipping depending on stock availability. Installation kits and technical documents may be included or available upon request.

• Most products come with a minimum 24-month legal warranty
• Replacements are brand new, not reconditioned
• Technical support and installation guides are usually provided for proper fitting

Express shipping options may be available for faster delivery if required.

Selecting a high-quality catalytic converter that meets or exceeds OEM standards offers several benefits:

• Guaranteed compliance with emission regulations and technical standards
• Reliable reduction of harmful exhaust gases ensuring environmental protection
• Durable stainless steel construction and advanced monolith coating technology
• Fitting kits and instructions included for correct installation
• Long-term warranty coverage and professional technical support
• No alteration to your vehicle’s fiscal or inspection status

This ensures a trouble-free experience and confidence in your vehicle’s emission control system.

For Audi A1 models with more powerful engines (like the 40 TFSI 200 hp from 2019 onwards, which differs from the 1.0 TFSI), sport or high-flow catalytic converters integrated with downpipes are available from specialist manufacturers. These offer:

• Improved exhaust flow and reduction restriction
• Performance gains in horsepower and torque, especially when combined with upgraded exhaust lines
• Construction in high-grade stainless steel (e.g., 304L) and racing-tested quality
• Homologation for CE certification allowing road use without check engine light

However, such options are not suitable or designed for the Audi A1 1.0 TFSI engine and should only be considered for compatible larger engines.

The catalytic converter is a key element of the Audi A1 1.0 TFSI's exhaust system. It is installed downstream of the engine to transform harmful exhaust gases via chemical reactions over catalysts that promote oxidation and reduction.

• It reduces hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx)
• Helps the vehicle comply with Euro 6 environmental standards
• Works alongside oxygen sensors and the exhaust gas recirculation system for optimal effectiveness
• Supports the vehicle passing emission tests and technical inspections

Maintaining a properly functioning catalytic converter is essential for environmental protection and the vehicle's legal compliance.

Catalytic converters can fail or degrade due to several reasons affecting vehicle performance and emissions:

• Blockage or contamination by unburned fuel, oil, or coolant leaks
• Physical damage from impacts or corrosion
• Failure of sensors or exhaust leaks causing error codes or warning lights
• Excessive engine temperature damaging the catalyst honeycomb
• General wear due to high mileage and aging

If you experience reduced engine power, increased emissions, check engine lights, or failed emissions tests, inspect the catalytic converter as part of diagnostics. Timely replacement ensures vehicle compliance and maintains environmental standards.
