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/V…
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 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.
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.
Analysis derived from Volvo technical bulletins (2014-2018) and aggregated owner-reported failure data (2016-2023). 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 D4204T is a powerful and refined engine, but its complexity (twin-turbo, emissions systems) demands diligent maintenance. The main concerns are the HP turbo actuator and DPF under short-trip conditions. With regular highway driving, strict oil changes, and using quality diesel/AdBlue, these engines can reliably exceed 250,000 km.
The top issues are high-pressure turbo wastegate actuator failure causing boost issues, Diesel Particulate Filter (DPF) clogging from short trips, AdBlue system crystallization, and intake manifold swirl flap motor failure. These are well-covered in Volvo service bulletins.
This 2.0L twin-turbo diesel engine, badged as 'D5', was used in the second-generation XC90 (2014-2018), the S90 sedan (2016-2018), and the V90 estate (2016-2018). It was Volvo's higher-output diesel option for these premium models during this period.
Yes, the D4204T responds very well to ECU remapping. Stage 1 tunes can safely increase output to around 180-200 kW and 450-500 Nm by optimizing fuel, boost, and EGR maps. The twin-turbo setup handles increased pressure well. Always ensure the DPF and cooling systems are in good condition before tuning.
Expect real-world figures around 7.0-8.0 L/100km (40-35 mpg UK) in combined driving for the XC90 D5. Highway cruising can drop to ~6.0 L/100km (47 mpg UK), while city driving can exceed 9.0 L/100km (31 mpg UK). Fuel economy is heavily impacted by DPF regeneration cycles and driving style.
Yes. The D4204T is an interference engine. If the timing chain were to fail (though very rare), the pistons would collide with the open valves, causing catastrophic internal damage. The chain is designed for the engine's lifetime with proper maintenance.
Volvo specifies a 0W-20 synthetic oil meeting their VCC 95200377 standard. This low-viscosity oil is crucial for protecting the twin turbos, ensuring efficient DPF operation, and optimizing fuel economy. Change intervals should not exceed 15,000 km or 12 months.
