What Could Cause the "Engine Fault Risk" Warning Light to Illuminate on a Renault Vehicle?

Model: Renault Renault Various
Part: Instrument cluster

Video tutorial

This video presents advice from a YouTuber regarding the illumination of a concerning warning light such as "engine fault risk" that may light up on the instrument panel of a Renault vehicle, which can appear alongside the "STOP" signal, causing significant stress.

The first issue could relate to the cooling system or a loose or damaged temperature sensor.

Check for leaks from the reservoir, examine the connections of the hoses, the radiator, and top up the fluid (water is acceptable temporarily) if you find a leak. The second issue is the fuel injector that may not be functioning correctly, causing fuel delivery problems.

A solution could be to clean it or replace it. The third issue is likely the 12-volt battery, which may be flat or faulty: the only solution is to replace the battery, especially if it is the original one or if it is three or four years old.
