The Volvo D5244T9 is a 2,400 cc inline-five turbo-diesel engine with integrated 48-volt mild hybrid technology engineered for premium sedans and wagons (2021–2023). It combines direct injection with a variable geometry turbocharger, intercooler, and an integrated starter-generator to deliver responsive torque and efficient cruising. Designed to meet Euro 6d emissions standards, it balances performance, refinement, and reduced tailpipe emissions.

The Volvo D5244T9 was used across Volvo's S60/V60/XC60/XC90 platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations-revised ECU calibrations for the XC90 to optimize torque delivery in urban environments and modified cooling circuit routing in the XC60-and from 2021 the facelifted S60 adopted the revised EGR cooler design to mitigate thermal cracking, creating interchange limits. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D5244T9 is fundamentally robust with excellent longevity when maintained properly. Its primary vulnerability is EGR cooler cracking, particularly on pre-2021 units. With timely replacement per SIB 2021-07-05, regular oil changes using Volvo VCC 0W-20, and avoidance of chronic short-trip driving, these engines commonly exceed 200,000 km without major repairs.
The most common issues are EGR cooler internal cracking causing coolant contamination, 48-volt ISG belt tensioner failure, DPF clogging due to incomplete regeneration, and high-pressure fuel pump wear. These are well-documented in Volvo service bulletins and owner reports. Cooling system leaks and CAN bus communication faults also occur but are less frequent.
The D5244T9 was used exclusively in Volvo models: S60 (2021–2023), V60 (2021–2023), XC60 (2021–2023), and XC90 (2021–2023). It was never licensed to other manufacturers. All variants are Euro 6d compliant with no market-specific emission tuning differences.
Limited potential exists due to its mild hybrid architecture and factory calibration. ECU remaps can yield modest gains of +10–15 kW by optimizing boost pressure and torque assist timing, but significant increases require aftermarket turbocharger, intercooler, and fuel system upgrades. The 48-volt system limits aggressive tuning due to electrical component thermal constraints.
Real-world fuel economy averages 6.5–7.5 L/100km (38–43 mpg UK) on mixed driving. Highway cruising yields 5.5–6.0 L/100km (47–51 mpg UK). Heavier models like the XC90 consume more. Economy depends heavily on maintenance condition—clean injectors, healthy EGR, and proper DPF regeneration are essential for optimal efficiency.
Yes. The D5244T9 is an interference engine. If the timing chain fails or jumps severely, pistons can contact open valves, resulting in catastrophic cylinder head damage. Regular inspection of chain tensioners and guides is critical to prevent this scenario.
Volvo specifies 0W-20 synthetic oil meeting Volvo VCC specification. Always use a quality oil formulated for modern turbo-diesel engines with mild hybrid systems and change it every 15,000 km or annually to ensure proper lubrication of the timing chain system, ISG, and high-pressure fuel pump. Using incorrect oil accelerates component wear and increases EGR cooler risk.
