The Volvo D 5244 T18 is a 2,400 cc, inline‑five turbo‑diesel engine produced between 2020 and 2024. It features a cast-iron block, aluminium head, dual overhead camshafts (DOHC), and a single variable geometry turbocharger (VGT). Output is rated at 195 kW (265 PS) and 540 Nm, targeting a blend of executive performance and long-distance efficiency.
Fitted exclusively to the S90 B5 and V90 B5 Cross Country, the D 5244 T18 was engineered for refined, effortless cruising with strong overtaking capability. Emissions compliance for all markets was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR), meeting stringent Euro 6d standards.
One documented concern is software calibration sensitivity in the engine control unit, particularly following updates, which can lead to transient fueling irregularities. This issue, highlighted in Volvo Service Bulletin RTJ‑48921, is addressed by installing the latest, validated software calibration to ensure optimal drivability and emissions control.
Production years 2020–2024 meet Euro 6d standards for all applicable markets (VCA UK Type Approval #VCA/EMS/VOLVO-B5).
The Volvo D 5244 T18 is a 2,400 cc inline‑five turbo‑diesel engineered for executive sedans and wagons (2020-2024). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver smooth, linear power and high torque. Designed to meet Euro 6d standards, it balances premium performance with regulatory compliance.

The inline-five configuration provides a uniquely smooth and linear power delivery but requires strict adherence to 15,000 km oil change intervals using Volvo VCC 95200 (0W-30) to prevent turbo and injector issues. The Bosch CP4.2 fuel pump demands ultra-low-sulfur diesel (ULSD) meeting EN 590 standards. Software calibration is critical; installing unvalidated or mismatched ECU software can lead to drivability issues per Volvo SIB RTJ-48921. The EGR system should be inspected for carbon buildup during major services.
Oil Specs: Requires Volvo VCC 95200 (0W-30) specification (Volvo SIB RTJ-48921). ACEA C5 is insufficient for long-term protection.
Emissions: Euro 6d certification applies to all 2020-2024 models for EU/UK markets (VCA Type Approval #VCA/EMS/VOLVO-B5).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across global markets with appropriate fuel quality (Volvo TIS Doc. VD-5244-20).

The Volvo D 5244 T18 was used exclusively in Volvo's SPA platform with longitudinal mounting and is designated as the 'B5' powertrain. This engine received platform-specific adaptations-optimized engine mounts for the S90 sedan and revised underbody shielding for the V90 Cross Country-and software calibrations were updated in 2022 to enhance refinement, creating minor ECU distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover, near the crankshaft pulley (Volvo TIS VD-5244-18). The 8th VIN digit is '5' for B5 variants. The engine is visually identified by its black cam cover and the 'B5' badge on the rear of the vehicle. Critical differentiation from the D 5244 T8 hybrid: The T18 is a pure combustion engine without high-voltage components or an electric motor. ECU software part numbers must be verified for compatibility; incorrect software can cause performance and emissions faults per Volvo SIB RTJ-48921.
The D 5244 T18's primary reliability risk is software calibration sensitivity in its engine control unit, with elevated incidence in vehicles subjected to non-standard or partial software updates. Volvo internal quality reports from 2021 indicated a notable number of vehicles exhibited drivability issues traceable to ECU software, while UK DVSA data shows SCR system faults are the most common emissions-related failure. Adherence to correct software update procedures and using the specified fuel is critical for long-term reliability.
Analysis derived from Volvo technical bulletins (2020-2023) and UK DVSA failure statistics (2021-2024). Repair procedures should follow manufacturer guidelines.
