The Renault 829 701 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2001 and 2006. It features a common rail direct injection system, a fixed‑geometry turbocharger, and dual overhead camshafts (DOHC). In standard form, it delivered 81 kW (110 PS) and 240 Nm of torque, designed for responsive performance in Renault's compact and mid‑size vehicles.
Fitted to models such as the Mégane II and Scénic II, the 829 701 engine was engineered for a balance of urban agility and highway cruising refinement. Emissions compliance was achieved through exhaust gas recirculation (EGR), allowing it to meet Euro 3 standards across its production run.
One documented reliability concern is premature failure of the high‑pressure fuel pump, often linked to fuel contamination or inadequate filtration. This issue, referenced in Renault Technical Note MEG‑03‑01, can lead to a complete loss of power. The pump design was revised in later service campaigns to improve durability.
Production years 2001–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault 829 701 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2001-2006). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong low‑end torque and efficient performance. Designed to meet Euro 3 standards, it balances everyday drivability with fuel economy.

The fixed-geometry turbo provides predictable power delivery but is susceptible to lag at very low RPM. Strict adherence to 15,000 km oil and filter changes using Renault RN0700 (5W-40) is critical to protect the turbo and fuel system. The Siemens common-rail system demands ultra-low-sulfur diesel (EN 590) to prevent injector and high-pressure pump failure. The timing belt must be replaced every 120,000 km or 5 years to prevent catastrophic engine damage, as this is an interference design. EGR valve cleaning is recommended every 60,000 km to maintain performance and emissions.
Oil Specs: Requires Renault RN0700 (5W-40) specification (Renault Technical Manual 829 701).
Emissions: Euro 3 certification applies to all 2001–2006 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Renault Group PT-2005).

The Renault 829 701 was used across Renault's Mégane II and Scénic II platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping differences for estate variants-and no significant facelift revisions occurred during its production, ensuring broad parts interchangeability. 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 (Renault Technical Manual 829 701). The 8th digit of the VIN is 'F' for vehicles equipped with the 829 701 engine. Visually, it can be identified by its black plastic rocker cover with "dCi 110" embossed on it and the Siemens VDO ECU mounted on the left side of the engine bay. Critical differentiation from the 829 700 (96 PS): The 829 701 has a larger intercooler and a different turbocharger actuator. Service parts are generally compatible across all 829 701 applications, but ECU software versions may vary by model year.
The 829 701's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Renault internal service data indicates a significant number of pumps required replacement before 150,000 km, while owner reports frequently cite EGR valve clogging as a secondary issue. Extended oil change intervals and contaminated fuel make adherence to the RN0700 specification and 15,000 km service intervals critical.
