The Volvo B 4154 T5 is a 1,498 cc, inline‑four turbocharged petrol engine produced between 2014 and 2018. It features an aluminium block and head, double overhead camshafts (DOHC), and direct fuel injection. In standard form, it delivered 180 kW (245 PS) and 350 Nm of torque, providing strong performance from a compact displacement through turbocharging and advanced engine management.
Fitted to models such as the V40 Cross Country, S60, V60, and XC60 during this period, the B 4154 T5 was engineered for responsive, efficient performance suitable for premium compact and mid-size vehicles. Emissions compliance was met through direct injection, turbocharging, and catalytic aftertreatment, allowing compliance with Euro 6 standards.
One documented reliability concern is premature wear of the timing belt tensioner pulley, which can lead to belt slippage or failure. This issue, highlighted in Volvo Service Bulletin SB‑16‑042, is often linked to material fatigue under high thermal loads. In 2017, Volvo introduced a revised tensioner design with improved bearing material.
Production years 2014–2018 meet Euro 6 standards (VCA UK Type Approval #VCA/VOL/B4154T5).
The Volvo B 4154 T5 is a 1,498 cc inline‑four turbocharged petrol engine engineered for premium compact and mid-size models (2014-2018).

The turbocharged direct-injection design provides strong low-end 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 RBS0-2AE02 (0W-20) oil is critical due to its low-viscosity formulation protecting the turbo bearings and timing belt tensioner. Extended idling should be minimized to reduce turbo heat soak. The timing belt and tensioner must be replaced per Volvo’s 10-year/160,000 km schedule. Ignoring SB-16-042 for tensioner replacement can lead to catastrophic belt failure.
Oil Specs: Requires Volvo VCC RBS0-2AE02 (0W-20) specification (Volvo Workshop Manual 2016). Supersedes ACEA C5 requirements.
Emissions: Euro 6 certification applies to all 2014–2018 models (VCA Type Approval #VCA/VOL/B4154T5).
Power Ratings: Measured under DIN 70020 standards. Figures represent engine output as installed in vehicle (Volvo Factory Brochure 2015).

The Volvo B 4154 T5 was used across Volvo's SPA and V40 platforms with transverse mounting. This engine received platform-specific adaptations-minor variations in turbo routing and engine mounts between hatchback and SUV body styles. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the timing cover (Volvo Workshop Manual 2016). The code will read "B4154T5". Visual identification: Aluminium block, direct injection fuel rail on the intake manifold, turbocharger mounted at the front of the engine. Critical differentiation from the B4204T: The B4154 has a 1.5L displacement (vs. 2.0L) and different bore/stroke dimensions. The "T5" suffix denotes the high-output turbocharged variant.
The B 4154 T5's primary reliability risk is timing belt tensioner pulley failure, with elevated incidence in high-mileage or heat-stressed examples. Volvo internal service data from 2016 indicated frequent need for tensioner replacement, while owner surveys highlight direct injection carbon buildup as a common cause of drivability complaints. Infrequent oil changes and use of incorrect oil make timing and fuel system issues critical.
