Pricing and Availability

Renault DF357 — Overview

  • Product: Renault DF357 diesel engine (marine/agricultural/industrial use)
  • Type: In-line diesel engine (4-stroke)
  • Typical applications: Small to medium boats, agricultural machinery, stationary power units, light industrial equipment
  • Manufacturer: Renault (diesel engines division; historically produced for multiple markets)
  • Oil is Life: Forget the long-life service schedule. Change the oil and filter every 6,000 miles (10,000 km) or annually. Use 5W-40 fully synthetic oil with RN0720 certification. Cheap oil kills the turbo.
  • Injector Bolt Inspection: Every second service, ask your mechanic to check the injector clamp bolt torque (spec is 18 Nm + 45° for the DF357). If you hear chuffing, fix it immediately.
  • Air Filter: Replace it every 12,000 miles. A blocked air filter encourages the EGR to clog faster.
  • Fuel Filter: Change it every 24,000 miles. The high-pressure fuel pump on the DF357 is intolerant of water in the diesel.

The Good (Why owners love it)

  • Fuel Economy: The DF357 is exceptionally frugal. Real-world driving returns 60-70 miles per gallon (UK) or 4-5 L/100km. In a time of rising fuel prices, this engine keeps running costs laughably low.
  • Tax Benefits: Because it meets Euro 4 standards, it avoids the harshest restrictions of older diesels in many European low-emission zones (though it is not ULEZ compliant in London).
  • Simplicity: Unlike later Euro 5 and Euro 6 versions, the DF357 lacks complex AdBlue systems and bulky DPF (Diesel Particulate Filter) setups that plague modern diesels.

If you are dealing with this code on your own vehicle, it is best to use a Renault-specific diagnostic tool to see the full sub-code (e.g., "Short circuit to ground" or "Signal out of range") to pinpoint the exact failure point.
