The Volvo D 4204 T23 is a 1,969 cc, inline‑four turbo‑diesel engine produced between 2015 and 2018. It features a high — pressure common — rail fuel system, a single variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form, it delivered 140 kW (190 PS) and 400 Nm of torque, providing strong low — rpm pull for effortless overtaking and towing.
Fitted primarily to the second — generation XC90 (T8 Twin Engine plug — in hybrid variant as the diesel…
Production years 2015–2018 meet Euro 6 standards .
The Volvo D 4204 T23 is a 1,969 cc inline‑four turbo‑diesel engineered for premium SUVs and estates (2015-2018). It combines a high-pressure common-rail injection system with a single variable-geometry turbocharger to deliver strong, linear torque and quiet operation. Designed to meet stringent Euro 6 emissions standards, it integrates with hybrid systems for enhanced efficiency.

The Volvo D 4204 T23 was used across Volvo's SPA platform with longitudinal mounting. This engine received platform-specific adaptations-integrated mounting for the T8 Twin Engine hybrid system in the XC90-creating specific service procedures. 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 T23 is generally robust when maintained correctly. Its main weakness is the high-pressure fuel pump, particularly in early models or with poor fuel quality. Adhering to strict service intervals with the correct 0W-20 oil and using only high-quality, low-sulfur diesel greatly enhances its longevity and reliability.
The most frequent issues are high-pressure fuel pump failures, AdBlue system warnings or malfunctions, EGR cooler leaks, and turbo actuator faults. These are well-documented in Volvo's service information and often relate to fuel quality, maintenance adherence, or component wear over time.
This 2.0L diesel engine was used in the second-generation XC90 (as part of the T8 Twin Engine hybrid), and in the first-generation S90 and V90 models (badged as D5). Production spanned from 2015 to 2018 across these premium Volvo platforms.
Aftermarket ECU tuning is common on the D-4204-T23 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 S90 D5 are around 5.0 L/100km (56 mpg UK). Real-world economy varies: expect 6.5-8.0 L/100km (35-43 mpg UK) in mixed driving, heavily influenced by driving style, traffic, and use of climate control. The XC90 T8's economy is dominated by its hybrid system usage.
Yes. Like virtually all modern engines, the D 4204 T23 is an interference design. If the timing chain were to fail, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Volvo mandates the use of their VCC 95200 specification, which is a 0W-20 synthetic oil. Using the correct low-viscosity oil is crucial for fuel economy, turbocharger protection, and the longevity of the emissions aftertreatment systems. Change intervals should not exceed 15,000 km or 12 months.
