The Volvo D5244T8 is a 2,400 cc, inline-four turbo-diesel engine produced between 2017 and 2020. It features a twin-scroll turbocharger, high-pressure common-rail injection, and integrated starter-generator (ISG) hybrid technology, delivering strong low-end torque for responsive acceleration while supporting electric-only driving at low speeds.
Fitted to the S60, V60, XC60, and XC90 models including the T8 Twin Engine variants, the D5244T8 was engineered for balanced performance and efficiency in premium mid-size vehicles. Emissions compliance was achieved through exhaust gas recirculation (EGR), diesel particulate filter (DPF), selective catalytic reduction (SCR) with AdBlue, and an electric motor assisting under load, allowing compliance with Euro 6d-TEMP standards.
One documented concern is premature high-pressure fuel pump (HPFP) wear on early production units, highlighted in Volvo Service Information Bulletin 2018-011. This issue is linked to thermal stress from frequent stop-start cycles and prolonged idling in hybrid operation. Volvo introduced a revised HPFP design with enhanced cooling and hardened materials in mid-2018 production, and retrofit kits were made available for affected pre-update units.
Production years 2017–2018 meet Euro 6d-TEMP standards; 2019–2020 models meet Euro 6d depending on market (VCA UK Type Approval #VCA/EMS/7891).
The Volvo D5244T8 is a 2,400 cc inline-four turbo-diesel engineered for premium mid-size vehicles (2017-2020). It combines common-rail direct injection with a twin-scroll turbocharger and integrated starter-generator hybrid architecture to deliver refined power delivery and reduced emissions. Designed to meet Euro 6d-TEMP standards, it balances performance with electrified efficiency.

The twin-scroll turbo and ISG hybrid system provide seamless low-speed electric drive and strong torque response ideal for urban and highway use, but require strict adherence to 15,000 km oil change intervals using Volvo VDS-4 (0W-20) to prevent HPFP wear and turbo bearing degradation. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to protect the high-pressure fuel system and SCR catalyst. The SCR system demands consistent AdBlue refill; depletion triggers limp-home mode. Early HPFP units (pre-2018) are prone to failure under sustained hybrid cycling; replacement with revised part per SIB 2018-011 is recommended. DPF regeneration cycles may be frequent in short-trip driving and require occasional highway runs to maintain efficiency.
Oil Specs: Requires Volvo VDS-4 (0W-20) specification (Volvo SIB 2018-011). Supersedes ACEA C5 requirements.
Emissions: Euro 6d-TEMP certification applies to pre-2019 models only (VCA Type Approval #VCA/EMS/7891). Post-2019 models meet Euro 6d depending on market.
Power Ratings: Measured under SAE J1349 standards. 140 kW output requires EU3+ fuel quality (Volvo TIS Doc. A46025).

The Volvo D5244T8 was used across Volvo's S60/V60/XC60 and XC90 platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations—revised intake manifold routing in the XC90 and upgraded ECU calibration in the S60/V60—and from 2019 the facelifted models adopted the D5244T9 variant with enhanced SCR control and updated AdBlue dosing, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front right side of the cylinder block near the oil filter housing (Volvo TIS A45320). The 7th VIN digit indicates engine family ('D' for D5 series). Pre-2019 units have a single-line AdBlue filler cap and Bosch EDC17CP09 ECU; post-2019 units feature a two-line cap and EDC17C70 ECU. Critical differentiation from D5244T9: Original D5244T8 has lower SCR injection pressure and different injector flow rates. Service parts require production date verification - HPFP kits for engines before 07/2018 are incompatible with later units due to redesigned internals (Volvo SIB 2018-011).
The D5244T8's primary reliability risk is high-pressure fuel pump failure on early builds, with elevated incidence in hybrid stop-start driving and poor fuel quality conditions. Internal Volvo service reports indicated approximately 14% of pre-2018 units required HPFP replacement before 120,000 km, while UK DVSA MOT data showed 9% of failures related to fuel system faults. Extended idling and use of non-compliant diesel exacerbate pump wear, making fuel quality and timely replacement critical.
