The Volvo D 5244 T20 is a 2,400 cc, inline‑five turbo‑diesel engine produced between 2014 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 162 kW (220 PS), with torque peaking at 470 Nm, providing strong low‑rpm pulling power for effortless overtaking.
Fitted primarily to the second‑generation XC90 (T8 Twin Engine variants) and S90/V90 models, the D 5244 T20 was…
All production years (2014–2018) meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volvo D 5244 T20 is a 2,400 cc inline‑five turbo‑diesel engineered for premium SUVs and sedans (2014-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver smooth, high‑torque performance. Designed to meet Euro 6 standards, it prioritizes refinement and long‑distance efficiency.

The Volvo D 5244 T20 was used exclusively in Volvo's SPA platform vehicles with longitudinal mounting. This engine was paired specifically with the T8 Twin Engine plug-in hybrid system in the XC90, and later in the S90 and V90 for certain markets, creating a unique compatibility profile. All adaptations are documented in OEM technical bulletins.
The D 5244 T20's primary documented concern is EGR system complexity within the T8 hybrid setup, with potential for software-related cold-start management issues. Volvo internal data indicates a low incidence of mechanical failures, while emissions system diagnostics are the most common service item. Adherence to prescribed maintenance schedules is paramount for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D 5244 T20 is generally considered reliable, benefiting from Volvo's mature diesel technology. Its integration into the T8 hybrid system adds complexity, but major mechanical failures are uncommon. Longevity is heavily dependent on strict adherence to maintenance, particularly oil changes and using the correct AdBlue fluid.
The most frequent issues are software-related, like EGR cooler condensation management (addressed by a TSB) and DPF/AdBlue system warnings due to driving patterns. Mechanical problems like turbo actuator calibration drift or injector issues are less common but documented in service bulletins.
This engine was used exclusively as the internal combustion component in the T8 Twin Engine plug-in hybrid variants of the second-generation XC90 (2015-2018), and later in the S90 and V90 (2016-2018). It is not found in conventional diesel-only Volvo models.
Tuning is complex and generally not recommended. The engine's output is intricately managed by the hybrid control system. Altering its parameters can disrupt the hybrid synergy, trigger fault codes, and potentially damage emissions components or invalidate warranties.
As part of the T8 Twin Engine system, official combined figures are around 2.1 L/100km, but real-world consumption varies drastically. When running on diesel alone, expect figures similar to a conventional 220PS diesel SUV, approximately 6.5-8.5 L/100km depending on driving style and conditions.
Yes. Like virtually all modern engines with DOHC and tight tolerances, the D 5244 T20 is an interference design. A timing chain failure would likely result in significant internal engine damage, necessitating a major rebuild or replacement.
Volvo mandates the use of fully synthetic oil meeting the VCC 95200 specification, typically SAE 0W-30. Using the correct oil is crucial for protecting the turbocharger, high-pressure fuel system, and ensuring proper operation within the hybrid system's thermal management.
