Exhaust Citroen C4 Picasso

Exhaust parts for the Citroën C4 Picasso include flexible pipes, exhaust pipes, rear silencers, catalytic converters, and connectors. These components primarily support diesel engines such as the 1.6 HDi 112 CV (DV6C) and 2.0 HDi 136/138 CV (DW10BTED4 or RHJ), especially for the model years 2013-2016.

Flexible pipes absorb vibrations, reduce noise, and accommodate thermal expansion between the engine, silencers, or catalytic converters. They come in various inner diameters (35-60 mm) and lengths (100-300 mm).

For the 1.6 HDi 112 CV (DV6C) engine, exhaust parts include pipes and silencers with lengths from 160 mm to 900 mm and weights from 0.1 to 6.3 kg. These parts may be adapted for vehicles with Diesel Particulate Filters (DPF) and include fittings such as M6 or M8 threads and diameters of 66 to 70 mm. Various connectors and collars are used to join components securely.

• Lengths: 160-900 mm
• Weights: 0.1 - 6.3 kg
• Fittings include M6 and M8 threads
• Diameter: 66-70 mm

These parts are designed for the Citroën brand's diesel 1.6 HDi engine models, ensuring compatibility and performance.

For the 2.0 HDi 136 CV (RHJ/DW10BTED4) engine, exhaust pipes and silencers have typical lengths between 160 mm and 490 mm, with light weights around 0.1 kg. Prices start from 38,90 € for compatible parts designed to fit the Citroën C4 Picasso diesel MPV variant years 2013-2016.

• Lengths: 160-490 mm
• Weight: approximately 0.1 kg
• Price indication: from 38,90 €

These parts ensure proper exhaust gas flow and meet requirements for Euro 6 compliant BlueHDi models.

The rear silencers (mufflers) play a key role in noise reduction of exhaust gases. For the Citroën C4 Picasso, the average garage replacement price is around 371 €, with a minimum of 268 € noted for some models. These silencers are designed to match the exhaust pipe diameters and engine characteristics of various C4 Picasso variants including diesel engines like the BlueHDi.

Catalytic converters available include original and universal types, compatible with Euro 4, Euro 5, and Euro 6 emission standards. They come in various sizes and diameters (such as 48 mm entry for universal Euro 4 types). High-performance and race catalytic converters also exist with higher CPSI rating for increased power handling, suitable for specific diesel engines like the 1.6 HDi and BlueHDi versions.

• Universal and specific models for diesel and petrol engines
• Diameter ranges: from about 48 mm to 76 mm
• Compatibility with Euro 4 to Euro 6 emission standards

Proper matching of the catalytic converter to the vehicle's engine code and emission standards is essential to ensure compliance and performance.

Exhaust smoke color can indicate various engine or exhaust system conditions:

• White smoke: Often caused by coolant leakage into combustion chambers, indicating a possible head gasket failure or coolant system issue.
• Blue smoke: Caused by engine oil burning due to worn valve seals, piston rings, or turbocharger issues, common in diesel engines like the BlueHDi.
• Black smoke: Usually from excessive fuel combustion or poor combustion efficiency, possibly due to fuel system faults or clogged air filters.
• Two-colored smoke: A mix of white and blue or black smoke can point to combined coolant and oil issues.

Checking engine condition, coolant levels, and the exhaust components such as the catalytic converter and DPF system will help prevent or diagnose smoke issues.

A strong exhaust smell inside the cabin can be caused by several factors:

• Leakage in exhaust pipes or connectors allowing fumes to enter the vehicle’s interior.
• Missing or damaged exhaust pipe segments leading to exhaust gases escaping near the cabin air intake.
• Faulty seals or suspension damage causing misalignment of exhaust components.

To prevent smells and ensure vehicle safety, it is important to promptly check and repair any exhaust leaks, confirm correct installation of pipe segments, and ensure proper sealing around the exhaust system.
