2003 PEUGEOT 3071.4L Diesel

The EPAS column can fail on the 307, causing heavy or unassisted steering. This is a dangerous fault that typically occurs without much warning.

The body control module (BSI) located under the scuttle area is vulnerable to water ingress from blocked pollen filter drains, causing erratic electrics including phantom warning lights, wiper faults and starting problems.

The 1.6 16v petrol engine is known for head gasket failures, leading to coolant loss, overheating and potential engine damage. Prevention through timely coolant changes is key.

The concentric clutch slave cylinder can develop internal or external leaks, causing a soft or sinking clutch pedal and eventually making gear changes difficult or impossible.

The ABS control module can fail, triggering the ABS warning light and disabling the anti-lock braking system. The module can sometimes be repaired rather than requiring full replacement.
