If your Citroën C4 Picasso has lit up the engine failure warning light, you are likely facing a mechanical issue that could lead to costly breakdowns if not addressed promptly. This model, especially in its 1.2 PureTech petrol engine version, has experienced recurring faults that impact its performance and safety.
In this article, we explain the most common causes, how to identify them, and the best solutions to prevent further damage.
Most Common Engine Failures in the Citroën C4 Picasso
Various owners of the Citroën C4 Picasso and Grand Picasso have reported mechanical problems affecting the engine performance. Here are the most common ones explained below.
Issues with the Timing Belt
One of the most serious and recurring failures is the premature deterioration of the timing belt in an oil bath. This problem can cause:
-
- Oil contamination with belt residues.
-
- Obstruction of lubrication channels.
-
- Excessive friction, leading to premature wear of internal parts.
-
- Catastrophic engine failure, requiring a very costly repair (may exceed €7.000).
Increased Oil Consumption and Its Impact
Many owners have noticed abnormal oil consumption in their engines. This symptom may result from premature wear of seals and piston rings, causing:
-
- Higher risk of engine seizure if the oil level is not topped up in time.
-
- Reduction in engine efficiency and power loss.
-
- Increased emission of polluting gases, affecting the vehicle’s homologation.
Power Loss and Ignition Failures
Another common failure is sudden power loss and difficulties in engine ignition. The causes may be related to:
-
- Dirty or faulty injectors.
-
- Deteriorated ignition coils.
-
- Fuel pump failure, preventing proper fuel supply.
How to Identify if Your Citroën C4 Picasso has Engine Failures
Detecting the early symptoms of an engine failure can save you from costly repairs. Pay attention to the following signs.
Most Common Warning Signs
-
- Engine failure warning light illuminated on the dashboard.
-
- Abnormal vibrations when starting or idling.
-
- Excessive smoke from the exhaust (white or blue).
-
- Burning smell inside the vehicle.
-
- Metallic or rubbing noise from the engine.
Initial Diagnosis to Prevent Severe Breakdowns
If you notice any of these signs, it is advisable to follow these steps before going to a workshop:
-
- Check the oil level and condition: If the oil is very dark or has residues, it may indicate contamination by belt particles.
-
- Scan the system with an OBD2 tool: This will allow you to read error codes and identify the exact problem.
-
- Perform a visual inspection: Look for oil leaks, loose connections, or damaged cables.
