Check injection
Dacia Check injection message: saturated particle filter
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
On the Dacia Sandero 3, 'Check injection' with the warning light (and on some versions the particle filter light) means the filter is saturated. The manual says to consult an authorised dealer.
Safety first
Stop and check this first
- If 'WARNING: Engine Failure Risk' appears with this message, Dacia says to stop and not restart the engine.
Safe checks you can perform
- Engine Failure Risk or STOP
- Filter light before the message
- Do not try to regenerate with the message active
Leave these tasks to a qualified professional

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 Dacia Check injection message
What they doWith the Dacia Check injection 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 look for codes explaining why the filter did not regenerate (sensors, exhaust temperature, injection).
They must show youthe codes linked to Dacia Check injection message with status (active or intermittent) and the freeze frame data.
In writingthe codes read with the Dacia Check injection message on, the technician's interpretation and whether they were cleared before or after the repair.
Filter measurement and workshop regeneration
What they doThe technician reads differential pressure and soot load in live data and, if no fault blocks it, runs regeneration with the tool; if the load is excessive, they consider cleaning or replacement.
They must show yousoot load and differential pressure before and after.
In writingthe procedure used, the cause of saturation and, if the filter is replaced, its reference.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Engine Failure Risk or STOP
- Who:
- you, with the car stopped somewhere safe.
- How:
- check whether 'WARNING: Engine Failure Risk' or the red STOP light appears with the message.
- Result that matters:
- whether there is a red message or light.
- If it appears:
- Dacia says to stop, not restart the engine and contact an authorised dealer.
- If only 'Check injection' with the orange light:
- go to the dealer without loading the engine.
- Evidence to keep:
- photo of the message and lights.

Filter light before the message
- Who:
- you, thinking back over the previous days.
- How:
- recall whether the particle filter light came on and whether you could drive until it went off.
- Result that matters:
- whether there was a filter alert without a full regeneration.
- If yes:
- matches the sequence Dacia describes; tell the workshop.
- If you did not see it:
- the workshop should check why it did not warn or whether there is another fault.
- Evidence to keep:
- note of when each light came on.

Do not try to regenerate with the message active
- Who:
- you, on the way to the workshop.
- How:
- drive normally, without attempting long high-rpm runs on your own.
- Result that matters:
- reaching the workshop without making the filter worse.
- If you arrive with no new alerts:
- the workshop diagnoses and decides on regeneration.
- If 'Engine Failure Risk' appears:
- stop and do not restart.
- Evidence to keep:
- distance driven with the message.

What it means
The Dacia Sandero 3 manual explains that the particle filter regenerates by itself if you keep driving until its light goes off. If the filter becomes saturated, the warning lights come on with the 'Check injection' message and you must see an authorised dealer. If 'WARNING: Engine Failure Risk' also appears with another light, stop and do not restart. The message does not say why regeneration did not complete.

Symptoms and causes
Probable causes · in order
- Saturated particle filterCommon
This is the case Dacia describes for the message. It fits if the filter light came on earlier and you could not drive until it went off.

- Regeneration cut short by short tripsPossible
Dacia advises at least 20 minutes on main roads every 200 km (124 miles). It fits mostly urban use.

Does Check injection still appear after these checks?
