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 ag…
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 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.
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.
Analysis derived from Renault technical bulletins (2003-2007) and UK DVSA failure statistics (2010-2020). 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 829 701 can be reliable with meticulous maintenance, particularly regarding fuel and oil quality. Its main weakness is the high-pressure fuel pump, which is sensitive to poor fuel. Regular oil changes with RN0700 spec oil and timely replacement of the timing belt are crucial for longevity beyond 200,000 km.
The most frequent issues are high-pressure fuel pump failure, EGR valve clogging, and turbo actuator faults. Glow plug failures are also common as the engine ages. These are well-documented in Renault service bulletins and require prompt attention to avoid further damage.
The 829 701 1.9 dCi 110 engine was primarily used in the Renault Mégane II (2002-2006) and Scénic II (2003-2006). It was not used in other Renault models or licensed to other manufacturers during its production run.
Yes, the 829 701 responds well to ECU remapping. A Stage 1 remap can safely increase power to around 130-140 PS and torque to 280-300 Nm. The standard internals are robust, but supporting modifications like a larger intercooler are recommended for sustained high performance.
Excellent for its era. In a Mégane II, expect real-world figures of around 6.5 L/100km in mixed driving, translating to approximately 43 mpg (UK). Highway cruising can yield figures closer to 5.5 L/100km (51 mpg UK) under optimal conditions.
Yes. The 829 701 is an interference engine. If the timing belt breaks or jumps, the pistons will collide with the open valves, causing severe and expensive engine damage. Strict adherence to the 120,000 km or 5-year replacement interval is non-negotiable.
Renault mandates the use of RN0700 specification oil, typically a 5W-40 synthetic. Using the correct oil is vital for protecting the turbocharger and high-pressure fuel system. Oil and filter changes should be performed every 15,000 km or annually.
