Why This Part Most Commonly Fails
ECUs On Small Urban Cars Like The Peugeot 107 And Citroën C1 Typically Fail Due To Electrical Stress Or Environmental Damage Rather Than Wear From Mechanical Use. Common Causes Include Water Ingress Or Corrosion At Connectors, Voltage Spikes From Faulty Charging Systems, Thermal Cycling Leading To Solder Joint Fatigue, And Physical Damage From Improper Handling. Failures Can Appear Suddenly After An Electrical Event Or Gradually As Intermittent Faults And Erratic Engine Behavior.
