The Volvo D4204T is a 1,969 cc, inline‑four twin‑turbo diesel engine produced between 2014 and 2018. It features a DOHC 16-valve architecture with sequential twin-turbocharging (small high-pressure + large low-pressure turbo) and high-pressure common rail direct injection. In its standard tune, it produced 140 kW (190 PS) and 400 Nm of torque, offering exceptional low-end response and strong mid-range pull.
Fitted primarily to the second-generation XC90 and S90/V90 models, the D4204T was engineered for dynamic, effortless performance and premium refinement. Emissions compliance for its production period was met through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue, aligning with Euro 6 standards.
One documented service concern involves the high-pressure turbocharger’s wastegate actuator, which can develop sticking or sluggish response, leading to boost control faults. This issue, referenced in Volvo service documentation, is often linked to carbon buildup or actuator diaphragm wear. Revised actuators were introduced in later production runs.
Production years 2014–2018 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/VOLVO-D42).
The Volvo D4204T is a 1,969 cc inline‑four twin-turbo diesel engineered for premium SUVs and estates (2014-2018). It combines sequential twin-turbocharging with common-rail direct injection to deliver exceptional low-RPM torque and seamless power delivery. Designed to meet stringent Euro 6 standards, it balances high performance with low emissions.

The sequential twin-turbo system provides near-instant throttle response and strong, sustained power but demands strict adherence to 15,000 km or annual oil changes with the specified 0W-20 oil to protect the turbos and emissions systems. The Bosch common-rail system requires ultra-low-sulfur diesel (ULSD) to prevent injector and high-pressure pump wear. The high-pressure turbo's wastegate actuator is a known wear item; symptoms like boost hesitation warrant inspection per Volvo SIB 02-011/16. Pre-2016 models are more susceptible.
Oil Specs: Requires Volvo specification VCC 95200377 (SAE 0W-20) (Volvo Owner's Manual MY2015).
Emissions: Euro 6 certification applies to all 2014–2018 models (VCA Type Approval #VCA/EMS/VOLVO-D42).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Volvo TIS Doc. VCC-11235).

The Volvo D4204T was used across Volvo's SPA platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the XC90 for enhanced refinement. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front left side of the cylinder block, near the timing cover (Volvo TIS VCC-11235). The 8th digit of the VIN is '5' for D5 (D4204T) engines. Visually, the engine features a distinctive black plastic intake manifold with "D5" embossed on the cover. Critical differentiation from the single-turbo D4 (D19T): The D4204T has two turbochargers visible on the exhaust side. Service parts for the turbo system and associated plumbing are specific to this twin-turbo variant.
The D4204T's primary reliability risk is high-pressure turbocharger wastegate actuator failure, with elevated incidence in pre-2016 models. Volvo service data indicates a notable number of replacements were performed under warranty, while owner reports frequently cite boost-related hesitation. Extended low-speed driving accelerates carbon buildup, making periodic inspection or cleaning critical.
