Turbo Hose 1.6 HDi Citroën C5 II/III Peugeot 407
This turbo hose is designed for the 1.6 HDi engines fitted to Citroën C5 (II/III) and Peugeot 407 models. It is a direct-fit replacement part often sought under the code 0382EC and intended for professionals and experienced DIY mechanics who perform turbocharger and intake system repairs. The hose restores proper boost delivery, reduces the risk of boost leaks and rough running, and helps maintain engine responsiveness and fuel economy.
Technical Information

- Product Codes: 0382EC
- Other Numbers: –
Function and Application
The turbo hose transfers pressurised air between the turbocharger, intercooler and intake manifold. It must withstand high temperature cycles, pressure spikes and occasional contact with engine oil and road contaminants. On 1.6 HDi engines the hose is a critical component of the forced-induction system — any leak will cause loss of boost, reduced performance, increased smoke or diagnostic fault codes related to boost pressure or turbo efficiency.
Common Symptoms of a Faulty Hose
- Loss of engine power and poor acceleration
- Whistling or hissing noises from the turbo/intake area
- Intermittent turbo lag or surging under load
- Increased fuel consumption and Check Engine Light related to boost/airflow
Most Common Reasons For Failure
Hoses typically fail due to heat ageing, repeated pressure cycles, oil contamination from turbocharger seals, incorrect or worn clamps, or mechanical damage from adjacent components. Rubber and silicone compounds harden and crack over time, while improper installation or over-tightening of clamps can cause splits at connection points.
Replacement Interval And Inspection
While turbo hoses can last many years, inspect them at regular service intervals or whenever turbo performance issues occur. For preventative maintenance, visually inspect hoses and clamps at every major service (typical recommendation: every 60,000–100,000 km) and replace at the first sign of cracking, soft spots, bulging or oil saturation.
Installation Recommendations
- Allow The Engine To Cool Before Starting Work; Hot Components Can Cause Burns.
- Relieve Any Residual Boost Pressure And Remove Intake Pipework Carefully.
- Inspect Mating Flanges, Intercooler Seals And Turbo Outlet For Damage Or Oil Residue; Clean Surfaces Before Fitting The New Hose.
- Use Appropriate High-Quality Clamps; Ensure Even Compression And Avoid Over-Tightening Which Can Damage The Hose Ends.
- After Installation, Start The Engine And Check System For Leaks Under Load (Idle And Light Acceleration). Re-Torque Clamps After A Short Test Drive.
- Replace Any Associated Gaskets, Seals Or Worn Clamps When Performing The Repair To Ensure A Reliable Long-Term Fix.
