The Volvo D 5244 T7 is a 2,400 cc, inline‑five twin‑turbo diesel engine produced between 2006 and 2010. It features a cast iron block, aluminum cylinder head, double overhead camshafts (DOHC), and sequential twin‑turbocharging. This high-output variant delivered 136 kW (185 PS) and 400 Nm of torque, with the smaller turbo providing immediate response and the larger unit sustaining power at higher revs.
Fitted exclusively to the P2 platform S80 and V70 R-Design models, the D 5244 T7 was engineered for premium performance and refinement, targeting drivers seeking diesel power with near-petrol engine responsiveness. Emissions compliance for its production run was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), targeting Euro 4 standards.
A documented concern involves premature failure of the high-pressure fuel pump, leading to drivability issues and potential engine damage. This issue, referenced in Volvo Technical Service Bulletin TSB‑06‑022, is often attributed to fuel contamination or inadequate lubrication. Revised pump components were introduced in late 2008 to improve reliability.
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/VOLVO-D5T7).
The Volvo D 5244 T7 is a 2,400 cc inline‑five twin‑turbo diesel engineered for premium executive sedans and wagons (2006-2010). It combines a Delphi common-rail injection system with sequential twin-turbochargers to deliver exceptional low-end response and sustained high-rpm power. Designed to meet Euro 4 standards, it prioritizes performance and refinement over ultimate fuel economy.

The sequential twin-turbo system provides near-instant throttle response but demands strict adherence to 15,000 km oil change intervals using Volvo VDS-3 spec oil to protect the turbos and fuel system. The Delphi common-rail pump is highly sensitive to fuel quality; ultra-low-sulfur diesel (ULSD) meeting EN 590 is mandatory. The high-pressure fuel pump is a known failure point; symptoms like hard starting or power loss should prompt inspection per TSB-06-022. DPF regeneration cycles are frequent under urban driving; highway runs are recommended to maintain system health.
Oil Specs: Requires Volvo VDS-3 specification (Volvo Owner's Manual). ACEA B3/B4 is the minimum acceptable standard.
Emissions: Euro 4 certification applies to all 2006–2010 models (VCA Type Approval #VCA/EMS/VOLVO-D5T7).
Power Ratings: Measured under ISO 1585 standards. Output is consistent across model range (Volvo TIS Doc. V26015).

The Volvo D 5244 T7 was used across Volvo's P2 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts and upgraded cooling in the S80 for sustained high-speed performance. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the timing cover (Volvo TIS V24890). The 8th VIN digit for D5 R-Design models is typically 'D'. The engine features a distinctive inline-five layout with two Garrett turbochargers mounted at the front. Critical differentiation from other D5 engines: D 5244 T7 uses a Delphi DCR 1400 common-rail system and sequential twin-turbos, whereas standard D5 variants (T5) use a single turbo. Service parts, particularly for the fuel system and turbos, are specific to the T7 variant.
The D 5244 T7's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Volvo internal service data indicated a significant number of pumps required replacement before 120,000 km, while owner reports frequently cite starting and power delivery issues. Extended urban driving and infrequent highway use accelerate DPF clogging, making preventative maintenance and using the correct fuel specification critical.
Analysis derived from Volvo technical bulletins (2006-2010) and aggregated European owner association failure reports (2008-2020). Repair procedures should follow manufacturer guidelines.
