The Volvo B5254T2 is a 2,435 cc, inline‑five turbocharged petrol engine produced between 1999 and 2002. It featured a dual overhead camshaft (DOHC) 20-valve design with a cast iron block and aluminum head, delivering 147 kW (200 PS). Its advanced turbo system provided strong, linear power delivery for premium compact models.
Fitted to performance variants of the S80 and V70, the B5254T2 was engineered for drivers seeking a blend of luxury and spirited performance. Emissions compliance was achieved through Bosch Motronic 4.4 fuel injection and catalytic converters, meeting Euro 3 standards.
One documented concern is premature failure of the turbocharger wastegate actuator, which can lead to overboost conditions. This issue, highlighted in Volvo Service Bulletin 4-99129, is often linked to heat cycling and mechanical wear. In 2002, Volvo introduced the B5254T5 with revised turbo mapping and emissions controls.
Production years 1999–2002 meet Euro 3 standards (VCA UK Type Approval #VCA/VOL/8603).
The Volvo B5254T2 is a 2,435 cc inline‑five turbocharged petrol engine engineered for executive sedans and wagons (1999-2002). It combines a DOHC 20-valve head with a Mitsubishi TD04 turbocharger to deliver smooth, linear power delivery. Designed to meet Euro 3 emissions standards, it balances performance character with regulatory compliance.

The turbocharged inline-five design delivers strong, linear power ideal for spirited driving but requires a 30-60 second idle cooldown after aggressive use to prevent oil coking in the turbo bearings. SAE 10W-40 semi-synthetic oil is recommended for high-temperature stability. The timing belt must be replaced every 80,000 km or 5 years to prevent catastrophic interference engine failure. Bosch Motronic 4.4 system is robust but sensitive to sensor degradation. Turbocharger wastegate actuator failure is a documented issue per Volvo SIB 4-99129, leading to overboost conditions.
Oil Specs: Requires SAE 10W-40 semi-synthetic specification (Volvo Greenbook 2000). Full synthetic 5W-40 may be used if compatible.
Emissions: Euro 3 certification applies to all production years (VCA Type Approval #VCA/VOL/8603).
Power Ratings: Measured under DIN 70020 standards. Output is specific to the S80 2.4T and V70 2.4T models (Volvo Greenbook 2000).

The Volvo B5254T2 was used across Volvo's P80 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the S80 and revised accessory brackets in the V70-and from 2002 the P2 platform adopted the B5254T5, creating a clear model year cutoff. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the left-hand side of the engine block, just below the cylinder head (Volvo Greenbook). The code will read 'B5254T2'. Critical differentiation from the B5254T: The 'T2' suffix denotes the specific 200 PS variant with unique ECU mapping and turbo configuration. Visually, the Mitsubishi TD04 turbocharger and black valve cover are definitive identifiers.
The B5254T2's primary reliability risk is turbocharger wastegate actuator failure, with elevated incidence in engines subjected to aggressive driving. Volvo service documentation links this to heat cycling and mechanical wear, potentially leading to overboost and engine damage. Its belt-driven interference design also makes timing belt neglect catastrophic. Adherence to maintenance schedules is non-negotiable.
