This code is primarily associated with communication failures on the vehicle's CAN bus (Multiplex) system, where the expected data from the instrument cluster or temperature sensors is missing or inconsistent. Key Technical Review Core Meaning
Some users report difficulty starting the car when the error is present.
In some contexts, particularly involving gearbox diagnostics on Renault models, it has been described as a "External Temp multiplex signal incoherence." Key Aspects of DF264: renault df264
This engine is not a revver. It makes peak power at relatively low RPMs. What it lacks in horsepower (typically around 45-50 HP in factory trim), it makes up for in sheer grunt. It pulls like a mule. Whether you are plowing heavy clay or powering a vintage sawbench, the DF264 just digs in and lugs down without stalling.

Because this is a "multiplexed" (communication) error, the issue is often electrical rather than mechanical.
With the battery disconnected, use a multimeter to measure the resistance across the CAN High and CAN Low pins at the OBD-II diagnostic port. A healthy network should register roughly . If it registers 120 Ohms, one of the terminating control modules has lost its connection entirely; if it reads close to 0 Ohms, the communication lines are shorted together.

He moved to the fuse box in the passenger compartment. He was looking for the "smart" fuse—a fusible link that often blew on these models when the relay stuck. It was intact.
The DF264’s death had long-term consequences. By choosing the Dauphine (a rear-engined car) over the DF264 (a front-engined FWD car), Renault locked itself into rear-engine development for another decade.
The fault is rarely a problem with the dashboard itself, but rather with the connections or power feeding it: Wiring and Connectors
