Description
EGR exhaust gas recirculation pipe for 2.0 HDI RHR engines for Citroën and Peugeot vehicles.
This genuine-quality EGR (Exhaust Gas Recirculation) pipe is designed for 2.0 HDI RHR diesel engines used in various Citroën and Peugeot models. Ideal for professional workshops and experienced DIY mechanics, the pipe replaces worn or damaged EGR piping to restore correct exhaust gas routing, reduce turbocharger issues and help maintain proper emissions control. Commonly searched by part numbers 9652264880 and 161836, this component is a direct-fit solution for vehicles listed below.
Function and Common Symptoms
The EGR pipe channels recirculated exhaust gases from the exhaust manifold or EGR valve back into the intake tract to lower combustion temperatures and reduce NOx emissions. When the pipe is compromised or blocked, typical symptoms include:
- Loss of engine performance and reduced throttle response
- Increased smoke from the exhaust and higher soot levels
- Intermittent turbo lag or unusual turbo behavior
- Check Engine Light with EGR-related fault codes
- Visible leaks or cracked piping in the EGR circuit
Fitment And Compatible Models
Compatible with a range of vehicles equipped with the 2.0 HDI RHR engine. Typical applications include:

Installation Recommendations
Recommended for installation by a qualified mechanic or an experienced DIY technician familiar with diesel engines. Basic installation guidance:
- Work on a cool engine and follow the vehicle manufacturer’s safety procedures.
- Access may require removal of engine covers, intake ducting or intercooler connections to reach the EGR pipe.
- Remove old clamps and gaskets; always replace sealing gaskets and O-rings to ensure leak-free assembly.
- Inspect adjacent components (EGR valve, cooler, turbo inlet) for soot buildup or oil contamination and clean as needed.
- Reassemble using correct fastener torque values from the manufacturer where available; perform a smoke/leak check after installation.
Why This Part Commonly Fails
EGR pipes are exposed to high temperatures and soot-laden exhaust gases. The most common failure causes are:
- Soot and carbon buildup that restricts flow and increases backpressure.
- Thermal fatigue and cracking from repeated heating and cooling cycles.
- Oil contamination from the turbo or crankcase ventilation, accelerating clogging and corrosion.
- Loose or degraded seals and clamps causing exhaust leaks.
Failure is more likely on higher-mileage vehicles or systems that have not been regularly inspected and cleaned. Replacing the EGR pipe and addressing root causes (cleaning EGR valve/cooler, checking PCV/turbo condition) helps prevent repeat issues.
Buy this EGR pipe if you need a direct-fit replacement for part numbers 9652264880 / 161836 — a practical choice for restoring proper EGR flow and engine performance in compatible Citroën and Peugeot 2.0 HDI RHR models.
