The Volvo D 5244 T21 is a 2,400 cc, inline‑five turbo‑diesel engine produced between 2010 and 2018. It features a DOHC valvetrain, common rail direct injection, and a variable geometry turbocharger (VGT), delivering robust power outputs from 158 kW (215 PS) up to 180 kW (245 PS) depending on the model year and application. Its five — cylinder layout provides a unique torque delivery and characteristic sound.
Fitted primarily to the second — generation S80, V70, XC70, and XC…
All production years (2010–2018) meet Euro 5 standards for relevant markets (EU Type Approval Certificate e13*2005/55*0218).
The Volvo D 5244 T21 is a 2,400 cc inline‑five turbo‑diesel engineered for executive sedans and SUVs (2010-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver smooth, linear power and high torque. Designed to meet Euro 5 standards, it balances premium performance with acceptable fuel economy.

The Volvo D 5244 T21 was used across Volvo's P3 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the XC60 and revised cooling ducts in the S80-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The D 5244 T21's primary reliability risk is timing belt tensioner pulley failure, with elevated incidence in high-mileage or poorly maintained vehicles. Volvo internal service data indicates a notable number of failures occurring after 120,000 km, while owner reports frequently cite a distinctive whining noise preceding failure. Neglecting the 15,000 km service interval or using incorrect oil makes timely pulley replacement critical.
Analysis derived from Volvo technical bulletins (2012-2017) and aggregated European owner association failure reports (2015-2023). 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 T21 is generally robust with strong performance, but its Achilles' heel is the timing belt tensioner pulley. Early failures were common, but the revised part (post-SIB) is much more durable. Strict adherence to the 15,000 km service interval and using Volvo VDS-4 oil are paramount for long-term reliability beyond 200,000 km.
The most frequent issues are timing belt tensioner pulley failure (causing noise or engine damage), DPF regeneration problems (leading to limp mode), EGR cooler leaks (causing coolant loss), and turbo actuator faults (resulting in boost loss). These are well-documented in Volvo service bulletins.
This 2.4L D5 diesel engine was used in the second-generation S80 (2010-2016), V70 (2010-2016), XC70 (2010-2016), and the first-generation XC60 (2010-2018). It was the primary D5 engine for these models during this period, replacing the earlier T12 variant.
Yes, the D 5244 T21 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 280-300 PS and torque to 550+ Nm. The stock internals and turbocharger are quite strong. However, supporting modifications like a performance intercooler are recommended for sustained high-power use.
Real-world fuel economy varies by model and driving style. In an XC60 D5 AWD, expect around 7.5 L/100km (38 mpg UK) combined. The S80 or V70 may achieve 6.5-7.0 L/100km (40-43 mpg UK). Highway cruising can yield 5.5-6.0 L/100km (47-51 mpg UK), while city driving may be 8.5-9.5 L/100km (30-33 mpg UK).
Yes. The D 5244 T21 is an interference engine. If the timing belt breaks or jumps due to tensioner failure, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes the 15,000 km belt and tensioner service absolutely critical.
Volvo mandates the use of VDS-4 specification oil, typically SAE 5W-30. This specific oil is formulated to handle the high pressures of the common rail system, protect the turbocharger, and minimize soot-related wear. Using the correct oil is vital for the longevity of the timing belt tensioner and other critical components.
