The Volvo B 4154 T4 is a 1,498 cc, inline‑four turbocharged petrol engine produced between 2014 and 2018. It features a dual overhead camshaft (DOHC) and four valves per cylinder, delivering a blend of efficiency and responsive performance. The engine utilizes direct fuel injection and a single-scroll turbocharger to produce 140 kW (190 PS) and 300 Nm of torque, enabling strong low-end pull.
Fitted to the second-generation Volvo V40 and S60/V60 P1 platforms, the B 4154 T4 was engineered for drivers seeking a balance of fuel economy, spirited acceleration, and premium refinement. Emissions compliance was achieved through advanced engine management, a close-coupled catalytic converter, and exhaust gas recirculation (EGR), meeting Euro 6 standards from launch.
One documented concern is premature high-pressure fuel pump (HPFP) failure, which can lead to drivability issues and no-start conditions. This issue, referenced in Volvo Service Bulletin T4-16-03, is often linked to fuel quality and lubrication characteristics under high-pressure operation. Volvo addressed this with revised pump internals and updated software calibration in later production.
Production years 2014–2018 meet Euro 6 emissions standards across all markets (EU Regulation (EC) No 715/2007).
The Volvo B 4154 T4 is a 1,498 cc inline‑four turbocharged petrol engine engineered for compact premium hatchbacks and sedans (2014-2018). It combines direct fuel injection with a single-scroll turbocharger to deliver strong low-RPM torque and efficient cruising. Designed to meet Euro 6 standards from launch, it balances responsive performance with stringent emissions control.

The turbocharged direct-injection design provides strong, linear 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 95200 (0W-20) oil is critical due to its low-viscosity formulation protecting the timing chain and turbo bearings. The high-pressure fuel pump demands high-quality, detergent-rich fuel to prevent premature wear. Post-2016 models feature revised HPFP internals; pre-2016 units should have the pump inspected if drivability issues arise per Volvo SIB T4-16-03. EGR systems require periodic cleaning to maintain emissions compliance.
Oil Specs: Requires Volvo VCC 95200 (0W-20) specification (Volvo Owner's Manual 2014). Supersedes ACEA C5 requirements.
Emissions: Euro 6 certification applies to all model years (2014-2018) for all markets (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across markets (Volvo PT-2016).

The Volvo B 4154 T4 was used across Volvo's V40 and P1 platforms with transverse mounting. This engine received minor ECU tuning for different markets, but no major platform-specific adaptations that affect core compatibility. All variants share the same block, head, and mounting points. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front of the engine block, near the timing cover (Volvo Workshop Manual). The code will read "B4154T4". Visually, it is an aluminum block engine with a plastic cam cover and a turbocharger mounted at the front of the engine. It is distinct from the larger B4204/B5254 engines by its smaller displacement and specific casting marks. Service parts for the B 4154 T4 are generally compatible across all V40/S60/V60 applications from 2014-2018, but ECU software and emissions components may vary by market.
The B 4154 T4's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in high-mileage or poorly fueled examples. Volvo internal service data indicated this was a leading cause of drivability complaints for early production units, while direct injection systems are susceptible to intake valve carbon buildup over time. Strict adherence to fuel and oil quality is critical for longevity.
