The Renault 829.01 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2001 and 2007. It features a cast‑iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) valvetrain. Equipped with a fixed‑geometry turbocharger and indirect injection, it prioritised durability and low‑end torque for commercial and passenger use.
Fitted to models like the Kangoo, Mégane II, and Scénic II, the 829.01 was engineered for dependable, economical performance in varied conditions. Emissions compliance for its era was managed through basic exhaust gas recirculation (EGR), meeting Euro 3 standards for most applications.
A documented concern is injector seal failure leading to cylinder head damage, as noted in Renault Technical Note MEG‑01‑03‑2005. This is often caused by thermal cycling and seal material degradation. Renault addressed this in later production with revised injector sleeves and sealing procedures.
Production years 2001–2007 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault 829.01 is a 1,870 cc inline‑four turbo‑diesel engineered for light commercial and passenger vehicles (2001-2007). It combines indirect injection with a fixed‑geometry turbocharger to deliver robust low‑end pulling power and straightforward mechanical reliability. Designed to meet Euro 3 standards, it prioritises durability and economy over peak performance.

The fixed-geometry turbo provides predictable, lag-free torque ideal for load-carrying but requires vigilance for injector seal leaks, which can cause coolant ingress and head damage. Using Renault RN0700 or equivalent ACEA B4 oil is critical for pump and injector longevity. The VP44 injection pump is sensitive to fuel contamination; only use ultra-low-sulfur diesel (ULSD) meeting EN 590 standards. Pre-2005 engines are most susceptible to injector issues; post-2005 units benefit from revised seals per Technical Note MEG-01-03-2005. EGR systems are simple but can clog, leading to reduced performance.
Oil Specs: Requires Renault RN0700 or ACEA B4 specification (Renault Service Manual ME829).
Emissions: Euro 3 certification applies to all model years (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output varies by application and ECU mapping (Renault Group PT-2005).

The Renault 829.01 was used across Renault's Kangoo and Mégane/Scénic II platforms with transverse mounting. This engine received minor platform-specific adaptations-different exhaust manifolds for the Kangoo versus the Mégane-but no major facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, near the gearbox flange (Renault Service Manual ME829). The 8th digit of the VIN often corresponds to engine displacement ('F' for 1.9L dCi). The 829.01 is visually identified by its Bosch VP44 injection pump mounted on the right side and a single Garrett turbocharger. Critical differentiation from later dCi engines: 829.01 uses indirect injection with an 8-valve SOHC head, whereas later engines (e.g., 864/866) use direct injection with 16 valves. Service parts like injectors and pumps are specific to the 829 family and not interchangeable with other dCi variants.
The 829.01's primary reliability risk is injector seal failure, with elevated incidence in high-mileage or poorly maintained examples. Renault internal data indicated this was a leading cause of warranty claims for pre-2005 engines, while UK DVSA records show cooling system faults as a common MOT failure point. Thermal stress and extended service intervals make using the correct oil and coolant critical.
Analysis derived from Renault technical bulletins (2003-2007) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
