Function
The pipe carries compressed air from the turbocharger into the vehicle intake tract or intercooler connection depending on configuration. Its role is to maintain correct boost delivery, prevent pressure loss and avoid unmetered air entering the engine that would affect fueling and engine management.
Replacement Procedure
Replacement is straightforward for a trained technician. Typical steps:
- Park the vehicle on level ground and allow the engine to cool.
- Loosen and remove clamps securing the pipe to the turbocharger and intercooler/intake connections.
- Inspect mating surfaces, intercooler and turbo outlet for oil residue or damage and clean if necessary.
- Fit the new pipe ensuring correct orientation and full seating on each connection. Use new or serviceable clamps and tighten securely without over-torquing.
- Start the engine and check for boost leaks under load or perform a simple boost pressure check. Verify there are no fault codes related to boost control or MAF readings.
Installation Recommendations
Use high-quality clamps and replace rusty or damaged clamps. Inspect adjacent hoses, intercooler seals and the turbo outlet for wear while the system is open. Clean oil deposits that can soften hoses and accelerate failure. After installation, perform a road test under various loads to confirm proper boost and engine response.
Most Common Failure Reasons
Intake pipes on turbocharged HDi engines most often fail due to age and heat cycling, which cause hardening and cracking. Oil contamination from turbocharger seals accelerates material degradation and softening. Other frequent causes include loose or corroded clamps, mechanical abrasion against nearby components, or damage from engine bay debris. Symptoms of a failing pipe include loss of power, fluctuating boost pressure, visible oil residue, hissing or whistling noises under boost, and related fault codes for air mass or turbo boost control.
Order this part by OE number for fastest compatibility lookup. The listed product codes are commonly used by professional workshops and independent mechanics repairing 2.0 HDI RHR engines in Citroën and Peugeot models.
