The Volvo B 4154 T3 is a 1,498 cc, inline‑four turbocharged petrol engine produced between 2014 and 2019. It features an aluminum block and head, dual overhead camshafts (DOHC), and direct fuel injection (Volvo VEA architecture). This unit delivered 110 kW (150 PS) and 250 Nm of torque, engineered for responsive performance and efficiency in Volvo’s compact executive models.
Fitted to models such as the S60, V60, and XC60 (Drive-E platform), the B 4154 T3 was designed for drivers seeking a balance of brisk acceleration, low-end torque, and refined cruising. Emissions compliance was achieved through a three-way catalyst and particulate filter, meeting Euro 6 standards across all markets.
One documented concern is carbon buildup on intake valves due to the direct injection system, potentially leading to rough idle and reduced performance. This issue, addressed in Volvo Technical Service Bulletin V‑17‑003, is common to many direct-injection engines and requires periodic cleaning. In 2019, Volvo began phasing in mild-hybrid variants of the Drive-E engines.
Production years 2014–2019 meet Euro 6 emissions standards (Swedish Transport Agency Type Approval #STV/B4154/2014).
The Volvo B 4154 T3 is a 1,498 cc inline‑four turbocharged petrol engine engineered for compact executive sedans, wagons, and SUVs (2014-2019). It combines direct fuel injection with a single-scroll turbocharger to deliver strong low-end torque and efficient performance. Designed to meet Euro 6 emissions standards, it balances responsive power delivery with modern fuel economy.

The turbocharged design provides strong low-RPM torque ideal for urban and highway driving but requires strict adherence to 15,000 km oil change intervals to prevent carbon buildup and turbo degradation. Volvo VCC 0W-20 oil is critical for optimal variable valve timing (VVT) operation and chain lubrication. Direct injection leads to carbon accumulation on intake valves; cleaning every 60,000-80,000 km is recommended per Volvo TSB V-17-003. The engine is non-interference, providing a safety margin if the chain fails.
Oil Specs: Requires Volvo VCC 95200377 specification oil (SAE 0W-20) for optimal VVT and chain performance (Volvo TSB V-17-003).
Emissions: Euro 6 certification applies to all models in this production period (Swedish Transport Agency #STV/B4154/2014).
Power Ratings: Measured under SAE net standards. Output is consistent across all applications (Volvo Tech Spec 2014).

The Volvo B 4154 T3 was used across Volvo's SPA/VEA platforms with transverse mounting. This engine received minor ECU and emissions revisions over its lifespan, but core components remain interchangeable. All adaptations are documented in OEM technical bulletins.
Locate the engine code on a label affixed to the timing cover or on the vehicle's VIN plate (Volvo Workshop Manual 2015). The code will read "B4154T3". Visual identification: Aluminum block and head, prominent "VOLVO ENGINE" casting on the plastic cam cover, and a single-scroll turbocharger on the exhaust manifold. Critical differentiation from B4204T: B4154T3 has a 1.5L displacement (75.0mm bore) vs 2.0L (82.0mm bore). Ancillary parts are generally consistent across model years; consult EPC for exact fitment.
The B 4154 T3's primary reliability consideration is carbon buildup on the intake valves, a well-documented characteristic of direct-injection engines addressed in Volvo TSB V-17-003. While not a catastrophic failure, it can lead to drivability issues if neglected. The engine's mechanical components, including the timing chain and turbocharger, are generally robust when maintained with the correct oil and service intervals.
