The Peugeot AHZ (DW10CD) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). This engine was designed to deliver a balance of 120 kW (163 PS) and 340 Nm of torque, with its high-pressure fuel system enabling strong low-rpm torque for everyday drivability.
Fitted to models such as the 308 II, 508 I, and Partner Tepee, the AHZ (DW10CD) was engineered for refined, economical motoring with ample pulling power. Emissions compliance for its production run was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting the stringent Euro 5 standard.
One documented reliability concern involves potential failures of the high-pressure fuel pump, which can lead to a no-start condition. This issue, referenced in Peugeot Service Bulletin 13BZ07A, is often linked to fuel contamination or inadequate lubrication. Later revisions incorporated design improvements to enhance pump durability.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot AHZ (DW10CD) is a 1,997 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2010-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The VGT turbo provides strong low-end torque ideal for urban and highway driving but requires strict adherence to 20,000 km or 12-month oil change intervals to protect the high-pressure fuel pump and turbo. Using PSA B71 2290 (5W-30) oil is critical due to its specific low-ash formulation protecting the DPF. The Bosch CP4 fuel pump demands ultra-low-sulfur diesel (ULSD) meeting EN 590 standards to prevent premature wear. EGR/DPF systems require periodic forced regenerations or cleaning to maintain emissions compliance and prevent performance issues. Service Bulletin 13BZ07A details the fuel pump replacement procedure for affected units.
Oil Specs: Requires PSA B71 2290 (5W-30) specification (Peugeot Owner's Manual). Compatible with ACEA C2/C3.
Emissions: Euro 5 certification applies to all 2010-2018 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Peugeot TIS Doc. B80112).

The Peugeot AHZ (DW10CD) was used across Peugeot's PF2/PF3 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 508 and specific ECU mapping in the 308-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot TIS B78850). The engine code 'AHZ' or 'DW10CD' will be clearly visible. The 8th digit of the VIN is typically 'R' for this 163 PS variant. Visually, it can be identified by its black plastic valve cover and the location of the EGR cooler on the intake manifold. Critical differentiation from earlier DW10 engines: The AHZ features a Denso or Bosch ECU with a specific 96-pin connector, while earlier variants used different ECUs. Fuel pump part numbers must be verified against the engine serial number for compatibility (Peugeot SIB 13BZ07A).
The AHZ (DW10CD)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Peugeot internal reports noted a cluster of pump failures requiring replacement before 100,000 km, while UK DVSA data indicates DPF-related issues are also common in short-trip vehicles. Extended oil change intervals and low-quality diesel make adherence to fuel and oil specifications critical.
