Exhaust Toyota Aygo

The Toyota Aygo, frequently equipped with a 1.0i petrol engine, often experiences issues with the exhaust flap (or valve). This causes loud noises, especially when cold, and can trigger error codes. Another common problem is blocked exhaust due to soot buildup, which requires regular maintenance. Broken exhaust supports are also reported but can be repaired inexpensively.

General symptoms of a defective exhaust on an Aygo include:

• Loud noises such as roaring (due to holes or perforation), metallic rattling (loose parts or rust), or dull sounds from deformations.
• Reduced engine performance: hard to rev, weak engine braking, increased fuel consumption, blue smoke emissions, or a lit catalytic converter warning light.
• Louder noise on acceleration (often from the silencer or catalytic converter) or at idle (usually from leaks).

These symptoms may also result from leaks, corrosion, detached internal elements, or faulty attachments.

The Aygo exhaust system consists of several key parts:

• Exhaust manifold (collector)
• Catalytic converter
• Intermediate silencer (expansion chamber)
• Rear silencer (muffler) which reduces noise after pollution treatment

Replacing the rear silencer is straightforward, usually involving loosening or cutting clamps. For diesel Aygo models, checking silencer wear and seal tightness is recommended.

Possible repairs include:

• Temporary fixes: repair paste, silicone mastic, or wraps for leaks or holes.
• Professional diagnostics to locate noise source and replacement of damaged silencers or catalytic converters if needed.
• DIY repairs such as fixing exhaust supports and collecting components, guided by online tutorials.

It is important to avoid worsening damage to ensure safety and reduce pollution.

Typical cost estimates include:

• Exhaust flap repair by a mechanic: around £160 (approx. 190 €)
• Fixing broken exhaust supports yourself: about £2.50 (approx. 3 €)
• Other repairs like sealing holes or replacing silencers vary depending on damage severity.

Prices depend on parts and labour; always seek professional advice for accurate quotes.

Many exhaust-related products like catalytic converters and diesel particulate filters (DPFs) come with a warranty up to 3 years or 100,000 km. These warranties cover manufacturing faults but do not cover wear or improper use.

• Always check if your parts are covered under warranty.
• Professional installation helps maintain warranty validity.

Consult the place of purchase or manufacturer for full terms and conditions.

Useful resources include:

• Automotive forums and communities dedicated to Toyota Aygo
• Instructional videos on platforms like YouTube for repairs such as exhaust support, silencers, and exhaust manifold replacements
• Automotive review and technical sites offering advice on noise problems and exhaust maintenance

Always verify tutorial compatibility with your Aygo model and year.

The cost to repair rust on an Aygo exhaust varies depending on the extent of the damage but a price around £180 is commonly reported by owners for flap repairs and similar work. This cost reflects labour and parts needed to restore proper function and reduce noise pollution.

• Minor repairs like fixing supports cost much less
• More severe rust damage may require replacement of components with higher costs

It is advisable to get a professional diagnosis to ensure fair pricing and quality repairs.

Sustaining your exhaust maintains car safety, sound, and emission compliance.
