The Renault K4M 813 was used across Renault's Mégane IV and Scénic IV platforms with transverse mounting. This engine received minor ECU calibration updates for emissions compliance, creating no significant interchange limits. 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.
The K4M 813's primary documented concern is electronic throttle body faults, similar to its predecessor, with higher incidence in vehicles exposed to dusty environments. Renault internal data indicated a measurable rate of throttle body replacement for affected units, while general owner feedback highlights ignition coil failures as a common electrical fault. The change to 5W-30 oil requires strict adherence to intervals to maintain engine protection.
Analysis derived from Renault technical bulletins (2016-2021) and aggregated owner-reported failure data (2018-2023). 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 K4M 813 is generally very reliable, representing the final and most refined iteration of the K4M engine family. Its main weaknesses are the electronic throttle body and ignition coils, common to many modern engines. With regular maintenance and using the correct RN0710 5W-30 oil, it is a dependable and long-lasting engine.
The most common issues are electronic throttle body faults, ignition coil failures, Variable Valve Timing (VVT) solenoid clogging, and PCV valve failure. These are well-documented in Renault service information and common repair guides. The switch to 5W-30 oil also requires strict adherence to service intervals.
The K4M 813 1.6L 16V petrol engine was used exclusively in the fourth generation of the Mégane (2016-2021) and Scénic (2016-2021). It was not fitted to the Duster or any Dacia/Nissan models, marking it as a late-model, emissions-focused variant for Renault's core European lineup.
Modest gains are possible. An ECU remap can typically yield an extra 5-8 kW by optimizing ignition and fuel maps. However, due to its focus on emissions and economy, the tuning potential is more limited than earlier, higher-compression K4M variants. Significant power increases are not recommended without internal modifications.
Fuel economy is excellent for its class. Expect around 7.8 L/100km in city driving and 5.2 L/100km on the highway in a Mégane IV, translating to approximately 36 mpg UK combined. This improvement over earlier K4M engines is due to the lower viscosity oil, revised engine mapping, and integrated exhaust manifold.
Yes. The K4M engine family is an interference design. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage requiring a major rebuild.
Renault specifies oil meeting the RN0710 standard, a 5W-30 low-SAPS (Sulphated Ash, Phosphorus, Sulphur) synthetic grade. This is critical for protecting the emissions system, particularly the catalytic converter. The service interval is generally 15,000 km or 12 months, whichever comes first.
