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 5008, the RHV engine was designed for drivers seeking a blend of power, refinement, and low emissions. Compliance with Euro 6d-TEMP and later Euro 6d-FINAL standards was achieved through a high-pressure common-rail fuel system, cooled exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and a selective catalytic reduction (SCR) system using AdBlue.
One documented concern for the RHV engine is sensitivity of the AdBlue injection system to low-quality or contaminated urea solution, which can trigger system faults and limit engine power. This issue, addressed in PSA service documentation, requires strict adherence to OEM-specified AdBlue fluid and system diagnostics for resolution.
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 VGT turbo provides strong, linear power delivery ideal for overtaking and towing but requires strict adherence to 20,000 km or annual oil change intervals with PSA B71 2290 (0W-30) oil to protect the timing chain and turbocharger. The SCR/AdBlue system is critical for emissions compliance; using only OEM-specified AdBlue fluid is mandatory to prevent injector clogging and system faults. Ignoring AdBlue warnings can lead to a vehicle immobilization event per EU regulations.
Oil Specs: Requires PSA B71 2290 specification (0W-30) (PSA Service Bulletin SB-19-02). ACEA C2/C3 is the minimum acceptable standard.
Emissions: Meets Euro 6d-TEMP (2018-2020) or Euro 6d-FINAL (2021 onwards) depending on model year (VCA Type Approval #VCA/EMS/8910).
Power Ratings: Measured under ECE R85 standards. Output is consistent for this variant (PSA Group PT-2020).

UNECE Regulation No. 85 (Engine Power Measurement)
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.
Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the gearbox flange (PSA Repair Manual 7100.A0). The 8th VIN digit often corresponds to the engine code for PSA vehicles. Visually, the RHV engine can be identified by its black plastic camshaft cover with "DW10" embossed on it and the presence of an AdBlue tank filler cap near the diesel fuel filler. Critical differentiation from the earlier DW10BTED4: The RHV (DW10UTD) features a more complex exhaust after-treatment system with a visible SCR catalyst and AdBlue injector, absent on pre-Euro 6d engines.
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.
