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 d…
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
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.
Analysis derived from Volvo technical service bulletins (2014-2019) and historical workshop manual data. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the B 4154 T3 is generally reliable long-term. Its main consideration is carbon buildup on the intake valves, a common trait of direct-injection engines, which requires periodic cleaning. With proper maintenance using the correct oil and adherence to service intervals, this engine can provide excellent longevity.
The most common issues are intake valve carbon buildup (causing rough idle), timing chain tensioner wear (rattle on cold start), turbocharger wastegate rattle, and PCV/oil trap failure (leading to oil consumption). These are well-documented and generally straightforward to address.
The B 4154 T3 was used in the facelifted second-generation S60 and V60 (2015-2018), and the second-generation XC60 (2017-2019). It was marketed as the entry-level turbocharged petrol engine in these models, offering a balance of performance and efficiency.
Aftermarket ECU tuning is common on the B-4154-T3 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is good for a turbocharged petrol engine. Expect around 7.5-9.0 L/100km (31-38 mpg UK) in mixed driving for an S60 or V60. Highway cruising can yield closer to 6.0-6.5 L/100km (43-47 mpg UK). Driving style and traffic conditions heavily influence consumption.
No. The B 4154 T3 is a non-interference engine. If the timing chain were to fail or jump, the pistons and valves would not collide, preventing catastrophic internal damage. This is a significant design safety feature.
Volvo specifies a very low-viscosity SAE 0W-20 oil meeting their VCC 95200377 specification. This is critical for the variable valve timing system's operation and overall engine efficiency. Using the correct oil is non-negotiable for optimal performance and longevity. Change oil every 15,000 km or annually.
