The Renault 810.05 is a 1,995 cc, inline — four turbo — diesel engine produced between 1987 and 1994. It features a single overhead camshaft, two valves per cylinder, and indirect injection via a pre — combustion chamber, delivering 66 PS at 4,200 rpm with torque of 140 Nm at 2,400 rpm. Its robust design prioritized durability and low — speed torque for commercial and family use.

Production years 1987–1994 meet pre-Euro emissions standards; compliance varied by national regulation .
The Renault 810.05 is a 1,995 cc inline-four turbo-diesel engine engineered for light commercial vehicles (1987–1994). It combines indirect injection with a mechanical fuel pump and fixed geometry turbocharger to deliver strong low-end torque and operational resilience. Designed to meet the emissions and efficiency expectations of its era, it balances simplicity with ruggedness.

The Renault 810.05 was used across Renault's Trafic platform with longitudinal mounting and no licensed external partnerships. This engine received platform-specific adaptations-revised intake manifold length in the Trafic L2 variant and modified fuel pump calibration for higher payload variants-and from 1990 the updated 810.05A adopted the hardened injector nozzle per Renault SIB 810-012, creating 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.
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 Renault 810.05 is mechanically simple and robust if maintained correctly. Early units (pre-1990) suffer from injector coking and fuel pump wear, but post-1990 revisions resolved these. Regular oil changes with SAE 15W-40 mineral oil and clean fuel are essential. Well-cared-for examples remain functional today with minimal issues.
The biggest issues are injector nozzle coking on pre-1990 units, turbocharger oil seal failure, timing chain stretch, and Bosch VE fuel pump seizure. These are well-documented in Renault service bulletins and owner manuals.
The 810.05 engine was used exclusively in the first-generation Renault Trafic van between 1987 and 1994. It powered variants including the Trafic 1.9 TD and Trafic 1.9 TD L2. No other Renault models or external manufacturers used this specific engine variant.
Very limited tuning potential exists. Minor gains of 5–8 PS are possible with a free-flow exhaust and recalibrated fuel pump. However, the SOHC design, indirect injection, and weak fuel pump limit significant upgrades. Forging higher outputs risks damaging the crankshaft or connecting rods due to stock internal strength thresholds.
Excellent for its era. In a Renault Trafic L2, typical consumption is approximately 8.5 L/100km (33 mpg UK) in city driving and 7.0 L/100km (40 mpg UK) on the highway, averaging around 35–38 mpg UK combined. Economy improves with clean injectors, proper timing, and correct fuel quality.
No. The Renault 810.05 is a non-interference engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage. However, loss of timing will still cause immediate stalling and require repair.
Renault specifies SAE 15W-40 mineral oil for all operating conditions. Modern synthetic oils are not recommended due to potential seal incompatibility. Oil must be changed every 10,000 km or annually, whichever comes first, to prevent injector coking and bearing wear.
