The Peugeot CRD93 (PSA) is a 2,179 cc, inline‑four turbo‑diesel engine produced between 1999 and 2006. It features indirect injection via a Bosch VP44 rotary distributor pump, a fixed — geometry turbocharger, and a single overhead camshaft (SOHC) design. Output is rated at 80 kW (109 PS), with peak torque of 250 Nm, providing robust pulling power for its era's mid — size vehicles.
Fitted to models like the 406 and 607, the CRD93 was engineered for long — distance comfort and lo…
Production years 1999–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/4567).
The Peugeot CRD93 (PSA) is a 2,179 cc inline‑four turbo‑diesel engineered for mid-size sedans and estates (1999-2006). It combines indirect injection with a fixed‑geometry turbocharger to deliver strong mid-range torque and dependable long-distance performance. Designed to meet Euro 3 standards, it prioritizes mechanical robustness over cutting-edge emissions technology.

The Peugeot CRD93 (PSA) was used across Peugeot's PF1 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 607-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
The CRD93's primary reliability risk is timing belt failure, as it is an interference engine. Peugeot internal service data indicates that neglected belt changes are the leading cause of major engine damage. UK DVSA data shows Bosch VP44 pump failures are common in high-mileage or poorly maintained examples. Extended service intervals and poor-quality fuel increase stress on the belt and pump, making adherence to the maintenance schedule critical.
Analysis derived from Peugeot technical bulletins (1999-2006) and UK DVSA failure statistics (2010-2020). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CRD93 is known for its strong torque and mechanical durability when properly maintained. Its primary vulnerability is the timing belt; failure causes catastrophic engine damage. With strict adherence to the 100,000 km belt change interval and use of quality oil, these engines can easily exceed 250,000 km. The indirect injection system is tolerant of lower-quality fuels, but the VP44 pump demands clean fuel and a stable electrical system.
The most frequent issues are timing belt failure (if neglected), Bosch VP44 injection pump failure, and EGR valve/carbon buildup. Glow plug failures are also common as the engine ages. These are well-documented in Peugeot service literature, particularly the critical importance of the timing belt and the sensitivity of the VP44 pump.
The CRD93 was primarily used in the Peugeot 406 (1999-2004) and 607 (1999-2006), often badged as '2.2 HDi 110'. It was also fitted to the Citroën C5 (2001-2004) as the '2.2 HDi 110'. All applications met Euro 3 emissions standards and were designed for the European market.
Yes, the CRD93 can be tuned. Simple modifications like adjusting the injection pump's fuel quantity or boost pressure can yield modest gains. More advanced tuning involves hybrid turbos or intercoolers. The engine's robust internals handle increased torque well, but pushing power too high can strain the clutch and transmission. Tuning the VP44 pump requires specialist equipment.
Fuel economy is very good for its size and era. In a Peugeot 406, expect 6.5-7.5 L/100km (38-43 mpg UK) combined. Highway cruising can drop to 5.5 L/100km (51 mpg UK). City driving will be higher, around 8.0-9.0 L/100km. Its indirect injection system is less efficient than modern engines but very forgiving.
Yes. The CRD93 is an interference engine. If the timing belt fails, the pistons will collide with the open valves, causing severe internal damage that usually requires a full engine rebuild or replacement. This makes the 100,000 km/6-year belt change interval absolutely non-negotiable.
Peugeot recommends an oil meeting ACEA B3/B4 or PSA B71 2290 specifications, typically a 10W-40 semi-synthetic or mineral oil. While not as fussy as modern engines, using a quality diesel-rated oil is still important for engine and turbocharger longevity. Change intervals should not exceed 15,000 km or 12 months.
