The Volvo D5252T is a 2,401 cc, inline‑five turbo‑diesel engine produced between 2001 and 2005. It features a cast iron block, aluminum cylinder head, double overhead camshafts (DOHC), and a single variable geometry turbocharger (VGT) for responsive power delivery. Output ranged from 120 kW (163 PS) to 132 kW (180 PS), with peak torque figures of 350–400 Nm.
Fitted primarily to the S60, V70, and XC70 models (including the 2.4D variants), the D5252T was engineered for refi…
Production years 2001–2005 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volvo D5252T is a 2,401 cc inline‑five turbo‑diesel engineered for mid‑size sedans and wagons (2001-2005). It combines DOHC valvetrain with a single variable‑geometry turbocharger to deliver smooth, linear power and strong mid‑range torque. Designed to meet Euro 3 standards, it prioritizes drivability and durability.

The Volvo D5252T was used across Volvo's P2 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the XC70 for off-road use-and featured no major facelift revisions during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The D5252T's primary reliability risk is turbocharger VGT mechanism failure, with elevated incidence in vehicles subjected to short trips. Volvo internal service data indicated a significant number of turbo replacements under warranty, while owner reports frequently cite EGR system clogging. Infrequent highway driving and poor fuel quality accelerate these issues, making preventative maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D5252T is robust mechanically but has known weaknesses in its turbo and fuel systems. With meticulous maintenance—especially using the correct oil and high-quality fuel—it can be very reliable. Addressing the turbo actuator issue early is key to longevity. Neglect, particularly infrequent oil changes, leads to premature failures.
The most frequent issues are turbo VGT actuator failure, EGR system clogging, and Bosch VP44 injection pump failure. Oil leaks from cam seals and injector seal leaks are also common. These are well-documented in Volvo service bulletins TSB-02-05-01 and TSB-01-03-02.
The D5252T was used in the first-generation (P2 platform) Volvo S60 (2001-2005), V70 (2001-2005), and XC70 (2003-2005), specifically in the 2.4D trim levels. It was not used in any vehicles outside the Volvo brand.
Yes, but cautiously. ECU remaps can yield modest gains (10-20 kW) by optimizing boost and fuel maps. However, the stock VP44 pump and turbo are near their limits. Aggressive tuning significantly increases the risk of turbo or pump failure. Supporting modifications are strongly advised for any power increase.
Real-world fuel economy is respectable. Expect approximately 7.5-8.5 L/100km (33-38 mpg UK) in mixed driving for an S60 or V70. Highway cruising can return figures closer to 6.0 L/100km (47 mpg UK). Economy suffers significantly if the EGR or turbo systems are malfunctioning.
Yes. The D5252T is an interference engine. If the timing belt (which drives the injection pump and balances shafts) or timing chain (which drives the cams) fails, valve and piston collision is likely, resulting in catastrophic engine damage. Adhering to the timing belt replacement schedule is non-negotiable.
Volvo mandates oil meeting specification VCC 95200377, typically a 5W-40 synthetic. ACEA B4 is the minimum acceptable standard. Using the correct, high-quality oil is critical for protecting the turbocharger bearings and preventing sludge buildup that can affect the VGT mechanism.
