Other Faults on This Variant

Clutch Slave Cylinder / Concentric Bearing Leak

Severe

2014-201970,000–120,000 miles£400–£800

The concentric slave cylinder (CSC) inside the gearbox bellhousing fails, leaking hydraulic fluid and causing clutch failure.

Turbocharger Actuator Failure

Moderate

2014-201960,000–120,000 miles£300–£600

The electronic boost pressure actuator on the Corsa E 1.4 turbo can fail, causing loss of boost and limp mode. The actuator controls variable boost and is a known failure point on this generation.

Timing Chain Tensioner Failure

Critical

2014-201960,000–120,000 miles£500–£900

The A14NET 1.4 turbo engine in the Corsa E is known for timing chain noise from the tensioner. Like many modern small-displacement turbo engines, the timing chain is not a lifetime component.
