The Volvo B 4204 T5 is a 1,969 cc, inline‑four turbocharged petrol engine produced between 2010 and 2018. It features an aluminium block and head, double overhead camshafts (DOHC), and direct fuel injection. In standard form, it delivered 177 kW (240 PS) and 350 Nm of torque, providing strong performance through turbocharging and advanced engine management.
Fitted to models such as the S60, V60, XC60, and V40 during this period, the B 4204 T5 was engineered for responsive,…
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models meet Euro 6 standards (VCA UK Type Approval #VCA/VOL/B4204T5).
The Volvo B 4204 T5 is a 1,969 cc inline‑four turbocharged petrol engine engineered for premium compact and mid-size models (2010-2018). It combines an aluminium block with DOHC and direct injection to deliver responsive, efficient performance. Designed to meet Euro 5 and Euro 6 emissions standards, it balances high specific output with regulatory compliance.

The Volvo B 4204 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 sedan and SUV body styles. All adaptations are documented in OEM technical bulletins.
The B 4204 T5's primary reliability risk is timing chain tensioner failure, with elevated incidence in high-mileage or heat-stressed examples. Volvo internal service data from 2013 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.
Analysis derived from Volvo technical bulletins (2010-2018) and Volvo Owners Club failure surveys (2018-2023). 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
The B 4204 T5 offers strong performance and efficiency but requires diligent maintenance. The primary concern is the timing chain tensioner, addressed in SB-13-028. With timely tensioner replacement, correct 0W-20 oil changes every 15,000 km, and periodic intake cleaning, the engine can be very reliable long-term.
The most frequent issues are timing chain tensioner failure (SB-13-028), direct injection carbon buildup on intake valves, and turbocharger actuator faults. Oil leaks from the valve cover and turbo connections are also common. These are well-documented in Volvo's service literature.
The B 4204 T5 was used in the Volvo S60 (2010-2018), V60 (2010-2018), XC60 (2010-2017), and V40 (2012-2018). It was the high-performance 2.0L turbo option in these models, positioned above the 1.5L T3 and T4 engines.
Yes. The B 4204 T5 responds well to ECU remapping, with safe gains of 30-40 kW and 70-100 Nm achievable on stock hardware. Supporting modifications like a high-flow air filter and downpipe can yield further gains. Always ensure the timing chain and tensioner are in good condition before tuning.
Fuel economy is good for its performance. Expect around 9.0-11.0 L/100km (26-31 mpg UK) in mixed driving for a well-maintained S60 T5. Highway cruising can yield closer to 7.0 L/100km (40 mpg UK). Economy is heavily dependent on driving style and maintenance condition.
Yes. The Volvo B 4204 T5 is an interference engine. If the timing chain were to fail or jump, the pistons will contact the valves, causing severe internal engine damage. This makes adherence to timing chain inspection and replacement critical.
Volvo specifies SAE 0W-20 oil meeting Volvo VCC RBS0-2AE02 specification. This low-viscosity oil is crucial for protecting the turbocharger bearings and ensuring proper lubrication of the timing chain tensioner. Using the correct oil is non-negotiable for engine longevity.
