When the message "Engine fault: Have the vehicle repaired" appears on the dashboard of your Peugeot or Citroën and activates the orange engine warning light, it can be quite alarming.
This message is common across both brands, including models like the Peugeot 208, 308, 508 and the Citroën C4, C5, Berlingo, etc. It can appear on both petrol and diesel engines.

What to do when the engine fault message appears?
Pull over safely
If this message suddenly appears while driving, try to pull over safely as soon as possible. This can help prevent further damage.
Use an OBD2 Car Diagnostics Scanner
To accurately identify the issue, you can use a Car Diagnostics Scanner. This tool allows you to read the fault codes and understand the source of the issue. These scanners are compatible with most Peugeot models like the 208, 308, or 508, and Citroën models like the C4, C3, etc.
If you don't have a scanner, consider buying or renting one to avoid the cost of a visit to the dealership.
Consult a professional if needed
If the cause of the issue isn't clear or if you're not comfortable with mechanical repairs, it's always safer to consult a mechanic.
Is it safe to keep driving?
In some cases, you may still be able to drive after the "Engine fault" message appears, but this depends on your Peugeot model and the specific cause of the alert. It is strongly advised not to continue driving long distances with this type of message. Here are some things to check depending on your vehicle:
- Peugeot 208 and 308: This message may sometimes appear due to a minor issue, such as a faulty sensor. If the engine still runs normally, you can probably drive to a garage without immediate danger.
- Peugeot 508: On this model, issues related to the DPF or EGR valve are common. If you experience a loss of power, stop as soon as possible and call for roadside assistance.
- Citroën C4: Models like the C4 or C4 Picasso may display this message due to injection system faults or a faulty oxygen sensor. If the engine runs fine and there’s no power loss, drive carefully to a garage, but don’t delay the repair.
- Citroën C5 and Berlingo: On these models, the "engine fault" message is often linked to DPF or injection issues. A power loss is a critical sign—stop immediately and do not continue driving.

Common causes of the "engine fault" message
The "engine fault" message can appear for many reasons and is often accompanied by an orange engine-shaped warning light. Here are the main possible causes:
Ignition system issue
This may be due to faulty spark plugs, ignition coils, or injectors. A failure in this system prevents the engine from running properly.
If you have some mechanical knowledge, you can inspect the spark plugs by removing them to check their wear.
EGR valve problem
This message can also be triggered by a clogged EGR valve. This valve, essential for reducing pollutant emissions, can become blocked over time. This is especially common in diesel versions of the Peugeot 508.
Diesel Particulate Filter (DPF)
The DPF is another common cause of this warning message. When clogged, the engine cannot operate efficiently, which causes the message to appear.
If you mainly drive in the city, it’s advisable to regularly clean the engine by driving on the highway at high RPMs.
Faulty oxygen sensor (lambda sensor)
The oxygen sensor measures the oxygen content in the exhaust gases. A malfunction can alter the air-fuel mixture, triggering the "engine fault" message.
What to do? You can check the sensors using a diagnostic scanner or ask a mechanic to do it. It’s a quick but essential step to avoid worsening the problem.
