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 load-carrying capability. Emissions compliance for this variant was achieved without a diesel particulate filter (DPF), meeting Euro 3 standards through optimized combustion and a basic exhaust gas recirculation (EGR) system.
A documented concern involves the Bosch VP44 injection pump, which can suffer from internal electronic or mechanical failure, leading to starting difficulties or power loss. This characteristic, referenced in Peugeot Technical Note 9905, is often attributed to voltage spikes or fuel contamination affecting the pump's sensitive electronics.
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 fixed-geometry turbo provides linear power delivery but lacks the low-RPM response of later VGT designs. The timing belt requires replacement every 100,000 km or 6 years to prevent catastrophic interference engine failure. The Bosch VP44 pump is robust but highly sensitive to electrical issues and fuel quality; ensuring a stable 12V supply and using clean, low-sulfur diesel is essential. The EGR system is relatively simple but should be inspected for clogging during major services (Peugeot Technical Note 9905).
Oil Specs: Requires ACEA B3/B4 or PSA B71 2290 specification oil (Peugeot Technical Manual 9772.A).
Emissions: Euro 3 certification applies to all 1999–2006 models (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across fuel grades meeting EN 590 specifications (Peugeot Technical Manual 9772.A).

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.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, below the injection pump (Peugeot TIS 9772.A). The 8th VIN digit for CRD93-equipped vehicles is typically 'C'. Visually, the CRD93 features a cast iron cylinder head and a prominent Bosch VP44 injection pump on the driver's side. Critical differentiation from naturally aspirated DW12 variants: CRD93 has a turbocharger and associated pipework. Service parts for the fuel system, particularly the VP44 pump, are specific to this engine code (Peugeot Technical Note 9905).
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.
