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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

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.
Aftermarket ECU tuning is common on the 829-701 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
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.
