RENAULT C1E-720 engine (2012–2019) – Specs, Problems & Compatibility Database

The Renault C1E 720 is a 898 cc, inline‑three turbocharged petrol engine produced between 2012 and 2019. It features an aluminium block and head, dual overhead camshafts (DOHC), and 12 valves. Equipped with direct fuel injection and a small, single-scroll turbocharger, it delivers responsive performance with strong low‑end torque for its size.

Fitted to models like the Clio IV and Twingo III, the C1E 720 was engineered to offer a fun, economical petrol option in city cars. Emissions compliance was managed through a three-way catalytic converter and electronic engine management, meeting Euro 5 standards for its production period.

A documented concern is potential turbocharger oil feed line clogging, which can lead to premature turbo bearing failure, as noted in Renault Technical Note CLI‑03‑08‑2015. This is often caused by extended oil change intervals or using incorrect oil viscosity. Renault recommends strict adherence to service schedules and the use of specified low-viscosity oil.

C1E-720 Technical Specifications

The Renault C1E 720 is a 898 cc inline‑three turbocharged petrol engineered for A‑segment city cars (2012–2019). It combines gasoline direct injection with a single‑scroll turbocharger to deliver peppy low‑end response and efficient urban performance. Designed to meet Euro 5 standards, it balances compact size with surprising power output.

Practical Implications

The small turbo provides brisk acceleration ideal for city driving but requires strict 15,000 km oil changes with Renault RN0700 5W-30 to prevent turbo oil feed line clogging and bearing failure. The direct injection system is prone to intake valve carbon buildup; periodic cleaning or using Top Tier fuel is recommended. Pre-2016 engines are most susceptible to turbo issues; adherence to Technical Note CLI-03-08-2015 regarding oil and maintenance is critical for longevity.

Data Verification Notes

Oil Specs: Requires Renault RN0700 or ACEA C2 specification 5W-30 (Renault Service Manual MEC1E).

Emissions: Euro 5 certification applies to all model years (VCA Type Approval #VCA/EMS/8765).

Power Ratings: Measured under SAE J1349 standards. Output varies by application and ECU mapping (Renault Group PT-2018).

C1E-720 Compatible Models

The Renault C1E 720 was developed for Renault's latest A‑segment platforms with transverse mounting. This engine features minor calibration differences between the Clio and Twingo but no major mechanical revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code on a label on the timing cover or stamped on the block near the gearbox flange (Renault Service Manual MEC1E). The 8th digit of the VIN often corresponds to engine displacement ('C' for 0.9L TCe). The C1E 720 is visually identified by its compact three-cylinder layout, direct injection fuel rail on the intake side, and a small Honeywell turbocharger. Critical differentiation from naturally aspirated engines: C1E 720 has a turbocharger and intercooler assembly. Service parts like turbos and injectors are specific to the C1E family.

Identification Details

Evidence:

Location:

Label on timing cover or block near gearbox flange (Renault Service Manual MEC1E).

Visual Cues:

  • Compact inline-three cylinder head
  • Direct injection fuel rail
  • Small Honeywell turbocharger and intercooler
Turbo Oil Feed Warning

Issue:

Extended oil change intervals or incorrect oil viscosity can cause the turbocharger oil feed line to clog, leading to bearing failure and turbo seizure.

Evidence:

Renault Technical Note CLI-03-08-2015

Recommendation:

Adhere strictly to 15,000 km oil change intervals using only Renault RN0700 5W-30. Inspect the turbo for signs of oil starvation if unusual whining or smoke is present, per Technical Note CLI-03-08-2015.

Common Reliability Issues - RENAULT C1E-720

The C1E 720's primary reliability risk is turbocharger failure due to oil feed line clogging, with elevated incidence in high-mileage or poorly maintained examples. Renault internal data indicated this was a leading cause of warranty claims for pre-2016 engines, while UK DVSA records show emissions system faults as a common MOT advisory note. Thermal stress and extended service intervals make using the correct oil critical.

Turbocharger oil feed line clogging
Symptoms: Whining/whistling noise from turbo, blue smoke from exhaust, loss of power, oil leaks from turbo housing.
Cause: Accumulation of sludge or carbon in the turbo oil feed line due to infrequent oil changes or incorrect oil viscosity, leading to oil starvation and bearing failure.
Fix: Replace the turbocharger and clean or replace the oil feed and return lines. Ensure correct oil type and strict adherence to service intervals.
Intake valve carbon buildup
Symptoms: Rough idle, hesitation under acceleration, decreased fuel economy, misfire codes.
Cause: Lack of fuel washing over intake valves (common with direct injection), leading to carbon deposit accumulation that disrupts airflow.
Fix: Perform walnut shell blasting or chemical cleaning of the intake valves. Use Top Tier detergent gasoline to help mitigate future buildup.
High-pressure fuel pump failure
Symptoms: Engine cranks but won't start, erratic running, loss of power, fuel pressure codes.
Cause: Internal wear or failure of the high-pressure fuel pump, often accelerated by contaminated fuel or lack of maintenance.
Fix: Replace the high-pressure fuel pump assembly. Ensure fuel system is clean and fuel filter is replaced at recommended intervals.
Ignition coil or spark plug failure
Symptoms: Misfires, rough running, lack of power, check engine light (misfire codes).
Cause: Normal wear and tear of ignition components, exacerbated by the engine's high specific output and turbocharging.
Fix: Replace faulty ignition coils and/or spark plugs with OEM-specified parts. Use only the correct heat range and gap specification.
