The Volvo B 4204 T2 is a 1,999 cc, inline‑four turbocharged petrol engine produced between 2010 and 2014. It features an aluminum block and head, dual overhead camshafts (DOHC), and direct fuel injection (Volvo VEA architecture). This unit delivered 132 kW (180 PS) and 300 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 4204 T2 was designed for d…
Production years 2010–2014 meet Euro 5 emissions standards (Swedish Transport Agency Type Approval #STV/B4204/2010).
The Volvo B 4204 T2 is a 1,999 cc inline‑four turbocharged petrol engine engineered for compact executive sedans, wagons, and SUVs (2010-2014). It combines direct fuel injection with a single-scroll turbocharger to deliver strong low-end torque and efficient performance. Designed to meet Euro 5 emissions standards, it balances responsive power delivery with modern fuel economy.

The Volvo B 4204 T2 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 4204 T2's primary reliability risk is premature wear of the timing chain tensioner, as documented in Volvo TSB V-12-008. This can lead to a characteristic rattle on cold start and, if neglected, potential chain misalignment. While not typically catastrophic due to the non-interference design, it requires prompt attention. The engine's other components, including the turbocharger and direct injection system, are generally robust when maintained with the correct oil and service intervals.
Analysis derived from Volvo technical service bulletins (2010-2014) 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 4204 T2 is generally reliable long-term. Its main known issue is timing chain tensioner wear, which is addressed by a service bulletin. With proper maintenance using the correct oil and adherence to service intervals, this engine can provide excellent longevity and performance.
The most common issues are timing chain tensioner wear (causing a rattle), intake valve carbon buildup (causing rough idle), turbocharger wastegate rattle, and PCV/oil trap failure (leading to oil consumption). These are well-documented and generally straightforward to address.
The B 4204 T2 was used in the second-generation S60 (2010-2013), first-generation V60 (2010-2013), and first-generation XC60 (2010-2014). It was marketed as the T4 engine, offering a balance of performance and efficiency below the higher-output T5 and T6 variants.
Aftermarket ECU tuning is common on the B-4204-T2 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 2.0L petrol engine. Expect around 8.0-9.5 L/100km (30-35 mpg UK) in mixed driving for an S60 or XC60 T4. Highway cruising can yield closer to 6.5-7.0 L/100km (40-43 mpg UK). Driving style and traffic conditions heavily influence consumption.
No. The B 4204 T2 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 low-viscosity SAE 0W-30 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.
