Exhaust Fiat Grande Punto (2005-2012)

The Fiat Grande Punto exhaust system, whether petrol (such as 1.4 T-Jet) or diesel (like 1.3 Multijet), often encounters issues including abnormal noises such as clacking or loud rattling, power loss linked to the EGR valve, and failure at pollution control tests due to elevated CO or lambda values.

Typical affected components are the silentblocks, silencers, injectors, and gas recirculation mechanisms.

On the 1.3 Multijet diesel models around 2008, intermittent engine light activation limiting speed to 70 km/h is often caused by faulty injectors or a blocked EGR valve affecting exhaust gas recirculation.

Diagnostic with an OBD scanner is essential to read error codes and identify the exact fault.

Different models present various symptoms:

• 1.4 T-Jet petrol engines sometimes produce clacking noises at the exhaust, requiring professional inspection.
• 1.3 Multijet diesel engines may generate loud rattling coupled with engine misfires, typically due to silencer wear or joint failure.

Additionally, noises perceived at the front may result from steering joints or motor silentblocks rather than the exhaust itself.

Older models similar to the Grande Punto (circa 1995) can fail MOT tests due to high CO and irregular lambda sensor readings. This is often linked to exhaust system dirtiness or incorrect adjustments.

• Cleaning or adjustment of lambda and CO sensors is recommended to restore compliance with environmental regulations.

Maintaining a clean and efficient catalytic converter and DPF is essential for reducing emissions and passing technical inspections.

Key services include:

• Replacement of the exhaust silencer by specialised garages, which is advised if corrosion or excessive noise occurs.
• Regular diagnostic testing with an OBD scanner to detect intermittent faults, especially engine warning lights.
• Inspection and maintenance of hub joints, silentblocks, and the EGR valve to avoid engine damage.
• Periodic cleaning or adjustment of lambda and CO sensors to meet emission standards.

Always consult professionals for diagnosis to ensure accurate repairs and safe vehicle operation.

Exhaust parts should be of high quality, manufactured in stainless steel (such as INOX 409) with certified performance to ensure durability and compliance with safety and pollution rules.

Krosfou offers brand-new, original exhaust components that meet European regulations and come with a 3-year warranty, emphasizing quality and reliability.

• Always choose new original parts rather than reconditioned ones for longevity and compliance.
• Consult professional mechanics to provide accurate quotes and ensure proper fitment on your Fiat Grande Punto model.

Reliable exhaust maintenance protects your car’s performance, safety, and environmental footprint.

Several useful online sources provide technical advice and user experiences about Fiat Grande Punto exhaust systems:

• Automotive forums discussing issues like power loss and EGR valve faults.
• Professional garage and diagnostic websites offering detailed troubleshooting guides.
• YouTube channels showing visual diagnostics and replacement tutorials.
• Official checks and standards explanations regarding emissions and lambda sensor values.

Always verify the date and relevance of the information, especially for models produced after 2012, and prioritise professional diagnostics for accurate solutions.

Follow these guidelines to ensure optimal exhaust system operation and vehicle safety :

• Regularly schedule professional diagnostics to catch faults early, especially if the engine warning light comes on.
• Inspect exhaust silentblocks and joints to prevent abnormal noises and vibrations that can indicate wear.
• Keep the EGR valve clean and functional to avoid power loss and increased emissions.
• Comply with legal pollution thresholds by maintaining your catalytic converter and sensors correctly.

By adhering to these rules, you help maintain your Fiat Grande Punto’s performance and compliance with safety and environmental standards.
