The Renault 843 720 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2012 and 2018. It features a high — pressure common — rail direct injection system, a variable — geometry turbocharger (VGT), and a dual overhead camshaft (DOHC) design. In its primary application, it produced 66 kW (90 PS), prioritizing fuel efficiency and low — end responsiveness for urban driving.
Fitted predominantly to the Clio IV and Captur (first generation), the 843 720 was engine…
Production years 2012–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8910).
The Renault 843 720 is a 1,461 cc inline‑three turbo‑diesel engineered for supermini and small SUV applications (2012-2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑rpm torque and exceptional fuel economy. Designed to meet Euro 5 standards, it balances urban drivability with low emissions.

The Renault 843 720 was used across Renault's Clio IV and Captur platforms with transverse mounting. This engine received minor ECU mapping adaptations for different body styles and no significant facelift revisions during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The 843 720's primary reliability risk is variable-geometry turbo actuator failure, with elevated incidence in vehicles used primarily for short urban journeys. Renault internal service data from 2016 indicated a significant number of warranty claims for actuators on pre-2015 builds, while UK DVSA data shows DPF-related faults as a common MOT advisory item. Infrequent highway driving and low-quality diesel make adherence to RN0720 oil specification and regular DPF regeneration cycles critical.
Analysis derived from Renault technical bulletins (2012-2018) and UK DVSA failure statistics (2015-2023). 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 843 720 can be reliable with proper maintenance, particularly regarding oil changes and ensuring the DPF regenerates properly. Its main weakness is the turbo actuator, especially in early (pre-2015) models used for short trips. Using high-quality diesel and adhering strictly to service intervals significantly improves long-term durability.
The most frequent issues are turbocharger actuator failure, DPF clogging, EGR system clogging, and injector seal leaks. Turbo and DPF problems are well-documented in Renault technical notes and are the most common causes of breakdowns for this engine, especially in urban environments.
The 843 720 engine was used in the fourth-generation Renault Clio (2012-2018) and the first-generation Renault Captur (2013-2018), specifically in the 1.5 dCi 90 PS variants. It was not used in other Renault models during this period.
Yes, the 843 720 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 80-85 kW (110-115 PS). However, pushing beyond this puts significant stress on the stock turbo actuator and clutch. Tuning also increases the risk of DPF clogging if regeneration cycles are not managed.
Real-world fuel economy is excellent. Expect around 5.0 L/100km (city) and 3.8 L/100km (highway), translating to approximately 56-62 mpg (UK) combined. Actual figures depend heavily on driving style and ensuring the DPF regenerates effectively.
Yes. The 843 720 is an interference engine. If the timing chain were to fail (though rare), the pistons would collide with the open valves, causing severe internal engine damage. This makes using the correct RN0720 specification oil critical for chain lubrication.
Renault specifies RN0720 specification oil, typically in 5W-30 viscosity. Using the correct oil is vital for protecting the turbocharger, timing chain, and ensuring proper DPF function. Never use an oil that doesn't meet the RN0720 standard, as it can lead to increased soot and premature component wear.
