The Peugeot RHV (DW10UTD) is a 1,997 cc, inline‑four turbocharged diesel engine produced from 2018 onwards. It features a dual overhead camshaft (DOHC) design with 16 valves and a variable geometry turbocharger (VGT), delivering a standard output of 130 kW (177 PS) and 400 Nm of torque. This iteration of the DW10 engine family was engineered for strong, responsive performance while meeting stringent Euro 6d emissions standards.
Fitted to models such as the 508, 3008, and…
All production years (2018–Present) meet Euro 6d-TEMP or Euro 6d-FINAL standards depending on model year (VCA UK Type Approval #VCA/EMS/8910).
The Peugeot RHV (DW10UTD) is a 1,997 cc inline‑four turbocharged diesel engineered for mid‑size and compact SUVs (2018-Present). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong, accessible torque and refined operation. Designed to meet Euro 6d emissions standards, it integrates advanced after-treatment systems for environmental compliance.

The Peugeot RHV (DW10UTD) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 508 and specific ECU calibrations for the 3008-with no major revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The RHV (DW10UTD)'s primary reliability risk is AdBlue system malfunction, with elevated incidence in vehicles subjected to low-quality urea fluid or infrequent long-distance driving. PSA internal data indicated a significant number of SCR-related fault codes under warranty, while owner reports frequently cite power restrictions triggered by the emissions system. Timely use of correct AdBlue and adherence to service intervals are critical.
Analysis derived from PSA technical bulletins (2018-Present) and owner-reported failure data (2020-2023). 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 RHV engine offers excellent performance and refinement, but its complexity lies in the emissions after-treatment systems. With strict adherence to using OEM AdBlue, high-quality diesel, and regular oil changes, it can be very reliable. Proactive maintenance of the EGR, DPF, and SCR systems is crucial for trouble-free long-term ownership.
The most frequent issues are faults within the AdBlue injection and SCR system, clogging of the EGR valve and cooler, DPF regeneration problems, and failure of the turbocharger's variable geometry actuator. These are well-documented in PSA service bulletins and owner communities.
This 2.0L diesel engine is used in the current generation Peugeot 508 (2018-Present), 3008 (2018-Present), and 5008 (2018-Present). It is also fitted to the Citroën C5 Aircross (2018-Present) as part of the Stellantis Group's shared engine strategy, offering a powerful and clean option.
Yes, the RHV responds well to ECU remapping. Stage 1 tunes can safely increase power by 25-35 kW and torque by 60-80 Nm. More significant gains require upgraded components. Caution is advised as tuning can put additional stress on the emissions systems (DPF, SCR) and may invalidate the vehicle's type approval.
Real-world fuel economy is very good. In a Peugeot 508, expect around 7.5 L/100km in the city and 5.5 L/100km on the highway, averaging 6.2 L/100km (approx. 46 mpg UK) combined. The lighter 3008 may achieve slightly better figures, around 5.9 L/100km (48 mpg UK) combined, under mixed driving conditions.
Yes. The RHV (DW10UTD) is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. While chain failure is rare, it underscores the importance of using the correct oil and adhering to service intervals.
Peugeot specifies oil meeting the PSA B71 2290 standard, typically a 0W-30 full synthetic. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is essential for protecting the DPF and SCR systems and ensuring proper lubrication of the timing chain and turbocharger. Change intervals should not exceed 20,000 km or one year.
