Description
Air connection at the intercooler for Peugeot and Citroën vehicles with 2.0 HDi engine.
This turbo hose (intercooler-to-intake connection) is designed for 2.0 HDi turbocharged diesel engines used in a range of Peugeot and Citroën models. Built to route pressurised charge air from the intercooler to the intake manifold, the hose ensures stable boost delivery and helps maintain engine performance and fuel efficiency. Commonly searched under the code 0382HV, this part is suitable for professional workshops and experienced DIY mechanics who perform turbo system maintenance or repairs.
Key Benefits
- Direct replacement for the original intercooler connection on compatible 2.0 HDi engines.
- Restores proper boost flow and prevents pressure loss that causes turbo lag and power loss.
- Durable construction to resist heat cycling and under‑bonnet contamination.
- Simple swap procedure for garages and competent DIYers—no special machining required.

Function And Role
The hose connects the intercooler outlet to the engine intake, carrying cooled, pressurised air from the turbocharger system. Maintaining an airtight, flexible connection is essential for correct boost pressure, engine response and emissions. Any leak, crack or collapse in this hose can lead to reduced power, rough running and increased fuel consumption.
How To Replace
Recommended for experienced mechanics or competent DIYers. Basic replacement steps:
- Allow The Engine To Cool Completely Before Starting Work.
- Remove Any Engine Covers Or Intake Ducting That Block Access To The Hose.
- Loosen And Remove Hose Clamps Or Quick‑Connects At Both Ends.
- Inspect Turbo Outlet, Intercooler Pipe And Sealing Surfaces For Damage Or Oil Residue.
- Fit The New Hose In Correct Orientation, Replace Clamps With New Quality Clamps If Possible.
- Tighten Clamps Securely Without Over‑Torquing; Ensure There Are No Twists Or Pinches In The Hose.
- Start The Engine And Check For Boost Leaks At Idle And Under Load (Road Test If Safe).
Installation Recommendations
- Always Use New Clamps When Replacing Turbo Hoses; Old Clamps Often Lose Clamping Force.
- Clean Mating Surfaces Of Oil And Debris To Ensure A Proper Seal.
- Inspect Adjacent Components (Intercooler, Turbo Outlet, Vacuum Lines) For Signs Of Oil Leaks Or Damage.
- Perform A Boost Leak Test After Installation To Confirm Integrity.
- Keep A Visual Record Of The Hose Orientation To Avoid Incorrect Reassembly.
Why The Part Fails Most Often
- Ageing And Heat Cycling: Repeated heating and cooling in the engine bay causes rubber and silicone materials to harden, crack or delaminate.
- Oil Contamination: Turbo oil leaks into the charge pipes accelerate material degradation and cause softening or collapse.
- Overboost Or Mechanical Stress: Faulty wastegate or turbo issues can create pressures beyond the hose rating, leading to bursts or blow‑offs.
- Poor Clamping Or Installation: Incorrectly fitted or loose clamps lead to air leaks and premature failure.
- Physical Damage: Contact with adjacent components, debris or prior poor repairs can abrade the hose.
Service Interval And Inspection
There Is No Fixed Replacement Interval For Turbo Hoses. Inspect Hoses At Every Major Service Or If You Notice Loss Of Power, Whistling/Whooshing Sounds Under Boost Or Visible Cracks. Replace Immediately If Any Signs Of Deterioration, Soft Spots, Bulges Or Oil Contamination Appear.
Part Number 0382HV Is Frequently Used As A Search Term By Mechanics And DIYers When Looking For This Specific Intercooler Connection Hose For 2.0 HDi Peugeot And Citroën Models.
