Exhaust Citroen C4 Grand Picasso

For the Citroën C4 Grand Picasso, especially diesel versions like 2.0 HDi 136/138 CV RHJ (DW10BTED4) and 1.6 HDi 112 CV 9HR (DV6C), various exhaust parts are available. These include new exhaust pipes and rear silencers, multiple clamping collars, rubber silent blocks, and flexible pipes. The parts are designed to fit specific engine models and comply with OEM specifications to ensure proper fit and function.

When selecting exhaust components, verify the compatibility with your specific engine model and year of the Citroën C4 Grand Picasso (e.g., 2.0 HDi or 1.6 HDi, production starting from 2007). Ensure the parts match the original technical specs, such as pipe diameter, thread sizes (e.g., M8, M10 x 1.25), and presence of particulate filters (DPF). This ensures proper functioning shortly after installation and prevents mechanical issues.

Yes, besides original fit parts, you can find universal exhaust components like rear silencers and flexible pipes compatible with the C4 Grand Picasso. Custom catalytic converters with different diameters and flow rates are also available for enhanced performance and sound. However, these should be chosen carefully to ensure they fit your engine model and comply with regulations.

• Universal rear silencers
• Flexible pipes with 35 mm diameter for engine to silencer connection
• Sport catalytic converters with various diameters and CPSI ratings

Keep in mind that all parts must be compatible with the engine’s requirements to avoid engine or mechanic issues.

Clamping collars and silent blocks are essential for securing exhaust components and reducing vibrations. Collars provide a tight seal between sections of the exhaust to prevent leaks and ensure mechanical stability. Silent blocks absorb vibrations to protect the exhaust and surrounding parts from damage and reduce noise inside the car.

• Multiple clamping collars with specific thread sizes (e.g., M8)
• Rubber silent blocks with varied weights for vibration dampening

Proper use of these ensures a robust and quiet exhaust system shortly after installation.

To ensure compatibility, always check the engine reference code (e.g., DW10BTED4, DV6C) and model year, as exhaust parts vary by these details. Use the vehicle identification number (VIN) when available to confirm component fitment. Refer to product specifications such as thread diameter, pipe dimensions, and particulate filter requirements. Consulting with a qualified mechanic can help avoid installation or engine issues shortly after fitting.

To maintain your exhaust system properly and avoid issues shortly after installation:

• Regularly check for leaks and secure clamping collars and silent blocks
• Avoid short trips that prevent the engine from reaching operating temperature, particularly in HDi engines with DPF
• Replace all gaskets, sensors, and injectors as recommended by the manufacturer
• Have your mechanic periodically inspect the exhaust system during engine servicing

These practices help keep the exhaust system in optimal condition and protect engine performance.

Exhaust parts supplied by reputable manufacturers come with a 3-year warranty, limited to use not exceeding 100,000 kilometers. Warranty conditions require professional installation with proper replacement of all associated components. Free returns are typically accepted within 30 days for unused parts in original packaging. Terms vary by supplier and product, so confirm conditions shortly after purchase.

• 3-year warranty coverage
• Free returns within 30 days on unused, original condition items
• Warranty limited to professional garage installation and adherence to instructions

Always consult the supplier’s warranty documentation for full details.

Yes, if the engine appears to idle roughly when stationary or if you notice exhaust fume smells inside the car, these could signal exhaust leaks or malfunctioning components. Such issues can affect engine performance and emissions. It is important to have a mechanic inspect the exhaust system shortly to identify and fix problems, ensuring safety and compliance with emission regulations.

Signs to watch for include:

• Exhaust fumes entering cabin
• Increased exhaust noise or juddering at speed
• Warning lights related to emissions or engine

Early diagnosis and repair can prevent further damage to the engine or exhaust system on your Picasso.
