Risk level
Critical
Stop using the equipment and contact a professional.
Urgency
Immediate
Quick answer
On the Dacia Sandero 3, 'WARNING: Engine Failure Risk' with the red STOP light means an injection fault, engine overheating or a serious engine fault. Stop as soon as traffic allows, switch off and do not restart.
Safety first
What to do now
- Stop at once and switch off
Who: you, when the message and STOP appear. How: stop as soon as traffic allows, switch off the engine and do not restart it. Result that matters: that the engine is off. If you stopped: call an authorised dealer or assistance. If you cannot stop at once: find the first safe spot without loading the engine. Evidence to keep: photo of the message, time and place.
- Accompanying light
Who: you, with the car stopped. How: check whether the coolant temperature or oil pressure light is red. Result that matters: which light comes with the message. If it is temperature: let the engine cool; do not open the coolant reservoir when hot. If it is another light or none: do not start; wait for assistance. Evidence to keep: photo of the lights.
- Earlier alerts
Who: you, thinking back over the previous days. How: recall whether 'Check injection', the particle filter light or the temperature light appeared before. Result that matters: whether there were earlier alerts. If yes: tell assistance and the workshop; it steers diagnosis. If no: the workshop starts from the fault memory alone. Evidence to keep: note of earlier alerts with dates.

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Fault memory behind Engine Failure Risk message
What they doWith the Engine Failure Risk message active, the technician connects a Dacia-capable diagnostic tool, reads stored and pending codes from every control unit and saves the freeze frame data for each one before clearing anything. They distinguish overheating, an injection fault or another serious fault.
They must show youthe codes linked to Engine Failure Risk message with status (active or intermittent) and the freeze frame data.
In writingthe codes read with the Engine Failure Risk message on, the technician's interpretation and whether they were cleared before or after the repair.
Test the affected system before starting
What they doFor temperature, the technician pressure-tests the cooling system and checks fan and thermostat; for injection, they measure fuel pressure and injectors; they check engine condition before running it.
They must show youthe pressure test or measurements against the manufacturer specification.
In writingthe cause, the engine condition after inspection and replaced parts with their references.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
