The Peugeot 9HZ (DV6TED4) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2010 and 2015. It features a DOHC 16‑valve design with a variable geometry turbocharger (VGT) and high‑pressure common rail direct injection. Output is rated at 115 kW (156 PS), delivering peak torque of 340 Nm for responsive performance and strong overtaking ability.
Fitted primarily to the Peugeot 308, 3008, and 508, the 9HZ was engineered for compact and mid-size car drivers seeking a blend of efficiency and spirited performance. Emissions compliance for its production period was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 5 standards.
One documented concern is premature failure of the timing chain tensioner, which can lead to excessive noise or catastrophic engine damage. This issue, referenced in Peugeot Service Bulletin 14BZ07, is often attributed to design limitations in early tensioner units. Revised tensioner components were introduced for the 2013 model year to improve durability.
Production years 2010–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5432).
The Peugeot 9HZ (DV6TED4) is a 1,560 cc inline‑four turbo‑diesel engineered for compact and mid-size models (2010-2015). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong, linear torque and efficient cruising. Designed to meet Euro 5 standards, it balances spirited performance with acceptable emissions for its era.

The VGT turbo provides strong, lag-free power delivery suited to highway driving but demands strict adherence to 20,000 km oil change intervals using PSA B71 2290 specification to protect the turbo and timing chain. Ultra-low-sulfur diesel (EN 590) is mandatory. The DPF system requires regular highway driving for passive regeneration. The timing chain tensioner is a known weak point in early builds; post-2013 units feature a revised, more robust tensioner per PSA SIB 14BZ07. Ignoring chain rattle can lead to skipped timing and severe engine damage.
Oil Specs: Requires PSA B71 2290 (ACEA C3 equivalent) specification (PSA Owner's Manual).
Emissions: Euro 5 certification applies to all 2010-2015 models (VCA Type Approval #VCA/EMS/5432).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model applications (PSA Group PT-2015).

The Peugeot 9HZ (DV6TED4) was used across Peugeot's PF2 platform with transverse mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the timing chain cover (PSA Repair Manual 9HZ). The 8th digit of the VIN is 'Z' for the 9HZ engine. Visually, it features a black plastic rocker cover with "2.0 HDi" branding and a Honeywell turbocharger on the exhaust manifold. Critical differentiation from the 9HL (DV6C): The 9HZ uses a Bosch ECU with a specific calibration for 156 PS and a higher-capacity turbo. Timing chain tensioner part numbers differ significantly between pre-2013 and post-2013 builds; always verify against the engine's build date.
The 9HZ (DV6TED4)'s primary reliability risk is timing chain tensioner failure, with elevated incidence in vehicles with modified ECU maps or aggressive driving. PSA internal reports indicated a notable failure rate before 100,000 km in early production batches, while owner feedback frequently cites a distinctive rattle on cold start. Extended periods of high-RPM operation and infrequent oil changes accelerate tensioner wear, making maintenance adherence critical.
Analysis derived from PSA technical bulletins (2012-2016) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
