The Volvo D 4204 T16 is a 1,969 cc, inline‑four turbo‑diesel engine produced between 2015 and 2019. It features a single twin‑scroll turbocharger, common rail direct injection, and dual overhead camshafts (DOHC), delivering 140 kW (190 PS) and 400 Nm of torque. The twin‑scroll turbo design enhances exhaust gas pulse separation, reducing lag and improving low‑end responsiveness for urban drivability.
Fitted primarily to the second‑generation XC90 (T6 Diesel) and S90…
All production years 2015–2019 meet Euro 6 standards .
The Volvo D 4204 T16 is a 1,969 cc inline‑four turbo‑diesel engineered for premium SUVs and sedans (2015-2019). It combines a twin‑scroll turbocharger with high‑pressure common rail injection to deliver smooth, linear power and strong low‑end torque. Designed to meet stringent Euro 6 standards, it balances performance with environmental compliance.

The Volvo D 4204 T16 was used across Volvo's SPA platform with longitudinal mounting. This engine received platform-specific adaptations-integrated engine mounts for the XC90 and revised engine bay shielding for the S90/V90-creating minor service part variations. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D 4204 T16 offers strong performance and refinement, but its long-term reliability hinges on meticulous maintenance. The high-pressure fuel pump is a known weak point, especially in early models. Using the correct 0W-30 oil, premium diesel, and adhering strictly to service intervals significantly improves longevity. Later models (post-2017) show improved pump durability.
The most frequent issues are high-pressure fuel pump (HPFP) failure, AdBlue system faults (crystallisation, injector leaks), DPF clogging from short trips, and EGR valve/cooler fouling. These are well-documented in Volvo service bulletins and often stem from maintenance neglect or poor fuel quality.
This engine was used in Volvo's larger, premium models on the SPA platform. It powered the second-generation XC90 (as the T6 Diesel) from 2015-2019, and the S90 and V90 sedans/wagons (badged as D5) from 2016-2019. It was not used in smaller models like the XC60 or S60 of that era.
Aftermarket ECU tuning is common on the D-4204-T16 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.
Official combined figures for the XC90 T6 Diesel are around 6.2 L/100km (45.6 mpg UK). Real-world consumption varies: expect 7.5-9.0 L/100km (31-38 mpg UK) in mixed driving, and 5.5-6.5 L/100km (43-51 mpg UK) on long highway runs. Short trips and DPF regenerations will increase consumption.
Yes. Like virtually all modern engines, the D 4204 T16 is an interference design. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very robust and rarely fails if oil is changed regularly.
Volvo mandates a very specific 0W-30 synthetic oil meeting the VCC 95200 specification. This low-viscosity oil is crucial for the engine's variable valve timing system, turbocharger lubrication, and protecting the high-pressure fuel pump. Using the wrong oil can lead to premature wear and system failures.
