Years later, when Étienne handed the keys to an eager apprentice, he did so knowing the DF357 would continue to warm up on chilly mornings, carry picnic baskets and toolboxes, and draw people together. The “hot” in its name had proven to be more than mechanical flair; it was the fire of passion that kept an old Renault alive and relevant, one meaningful mile at a time.

In automatic or CVT-equipped Renault models (like the Megane 2.0L), a localized "hot" transmission environment alters how the TCU processes shifting parameters. If the transmission fluid overheats, it can cause sensor drift, triggering a cluster of codes including DF357 and transmission speed sensor faults (like DF048 ) due to desynchronized RPM metrics.

Renault, a renowned French automaker, has been a staple in the global automotive industry for decades. With a wide range of models, from the popular Clio to the rugged Master van, Renault has built a reputation for producing reliable and efficient vehicles. However, like any complex machine, Renault cars can sometimes experience issues, and one error code that has been causing concern among owners is the DF357 hot.

The DF357 relies on a viscous (silicone) fan clutch. When these fail, the fan spins at 20% of its required speed. You won't hear the "roar" of the fan when the engine gets hot. Without that roar, the engine bay becomes an oven.

Raise the vehicle and inspect the tone rings on the wheels identified in Step 1. Look closely for: Trapped metallic debris or small pebbles.

Disconnect the negative battery terminal. Wait 15 minutes (to drain residual charge in the capacitors). Reconnect the terminal. Start the car and turn the steering wheel lock-to-lock. Drive for 5 km. Note: This clears temporary glitches but will not fix a hardware issue. [Connect Renault CLIP / PyRen] ➔ [Isolate ECU

Understanding how to read this code, why it triggers, and how to fix it will protect your transmission from total mechanical collapse. What Does Renault DF357 Mean? In automatic or CVT-equipped Renault models (like the

Restricted coolant or airflow stops the transmission from shedding heat.

The DF357’s original engine was modest — an air-cooled four-cylinder built for reliability, not speed — but this particular example had an aftermarket history. In the 1960s a private mechanic had fitted larger carburetors, a lightened flywheel, and a custom exhaust that let the engine breathe better. Those changes gave the DF357 the kind of spirited throttle response that made it “hot” among local enthusiasts: quick off the line, lively in the bends, and with a bark from the tailpipe that announced itself before headlights did.

For 2.0L Renault Megane models equipped with a CVT, DF357 is often flagged in the transmission control unit. This may require checking the transmission fluid level and quality or inspecting the electronic control module.
