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.

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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The D 5244 T7 is a high-performance engine known for its strong power delivery. Its main weakness is the high-pressure fuel pump, which can fail prematurely with poor fuel quality. The sequential turbos are generally robust. With strict adherence to oil changes, using high-quality diesel, and ensuring regular DPF regeneration, these engines can reliably exceed 250,000 km.
The most frequent issues are high-pressure fuel pump failure, DPF clogging (especially with urban driving), and faults with the turbocharger actuators/solenoids. Oil leaks from the turbo oil lines are also common as the engine ages. These are well-documented in Volvo service bulletins.
This high-output 2.4L D5 diesel was used exclusively in the S80 (2006-2010) and V70 (2007-2010) R-Design models. It was the top-tier diesel engine for these vehicles, offering significantly more power and torque than the standard single-turbo D5 variants.
Yes, it has good tuning potential. The sequential twin-turbo setup and robust internals can handle modest power increases (20-30 kW) via ECU remapping. However, pushing it further significantly increases stress on the already vulnerable fuel pump and turbos. Any tuning must be accompanied by upgraded cooling and strict maintenance.
Fuel economy is moderate for its performance. Expect approximately 9.5 L/100km (city) and 6.5 L/100km (highway), or roughly 30 mpg UK combined in an S80 R-Design. The V70 R-Design, being slightly heavier, will return similar or marginally worse figures. DPF regeneration cycles can temporarily increase consumption.
Yes. Like most modern engines, the D 5244 T7 is an interference design. If the timing chain were to fail (a very rare occurrence on this engine), the pistons would collide with the open valves, resulting in catastrophic engine damage requiring a rebuild.
Volvo specifies an oil meeting the VDS-3 standard, typically a 5W-30 viscosity for this model year. Using a high-quality, manufacturer-approved oil is crucial for protecting the twin turbos and fuel system. Change intervals should not exceed 15,000 km or 12 months.
