The Peugeot 9HR (DV6C) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2006 and 2014. It features a high — pressure common — rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard European specification, it produced 80 kW (109 PS) and 240 Nm of torque, engineered for compact car efficiency with strong low — end pull.
Fitted primarily to the Peugeot 207, 308, and Citroën C4 platforms, the DV6C was designed fo…

The Peugeot 9HR (DV6C) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and estates (2006-2014). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low-end torque and efficient urban performance. Designed to meet Euro 5 standards, it balances everyday drivability with low emissions.

The Peugeot 9HR (DV6C) was used across PSA Group's PF2 platform with transverse mounting. This engine received platform-specific adaptations-lighter engine mounts in the 207 and specific ECU mapping for the 308-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The DV6C's primary reliability risk is EGR valve failure due to carbon buildup, with elevated incidence in high-mileage vehicles operating in stop-start conditions. PSA internal reports from 2012 indicated a significant number of failures before 100,000 km, particularly in urban environments. Short-trip driving and extended oil change intervals are key aggravating factors, making adherence to the maintenance schedule critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DV6C is a compact and efficient engine, but its long-term reliability is closely tied to addressing the known EGR valve issue. Vehicles that have had the valve cleaned or replaced and received the ECU update per PSA bulletin 4488 F, and which receive strict, timely oil changes with the correct specification, can be very reliable beyond 150,000 km.
The most critical issue is EGR valve sticking due to carbon buildup. Other common problems include DPF clogging from short trips, turbocharger actuator faults, and injector seal/nozzle coking. These are well-documented in PSA service bulletins and owner reports.
This 1.6L HDi engine was primarily used in the Peugeot 207 (2006-2013) and 308 (2007-2013). It was also fitted to the equivalent Citroën C4 (2006-2013), always in the 110 PS variant, providing a balance of performance and economy for these compact cars.
Aftermarket ECU tuning is common on the 9HR-DV6C platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is excellent for its class. In a Peugeot 207, expect around 4.8 L/100km (59 mpg UK) in combined driving. Highway cruising can yield figures closer to 4.2 L/100km (67 mpg UK). Real-world economy is heavily influenced by driving style and trip length, with short urban trips significantly reducing efficiency due to DPF regeneration.
Yes. Like virtually all modern engines, the DV6C is an interference design. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal damage. Fortunately, the timing chain is very durable on this engine.
Peugeot mandates the use of oil meeting the PSA B71 2296 specification, typically a 5W-30 synthetic. Using the correct oil is critical for protecting the turbocharger and minimizing soot buildup in the EGR system. Change intervals should not exceed 20,000 km or 12 months.
