OBD Codes

None

Symptoms

A single loud 'click' when turning the key, but engine doesn't crank
Engine cranks very slowly despite a fully charged battery
Whirring or grinding noise after the engine starts

Root Cause

The carbon brushes inside the motor wear down to the copper wiring, or the contacts inside the solenoid burn out from repeated arcing.

How To Fix

Confirm battery voltage is strong under load (to rule out a dead battery).
Replace the starter motor unit.
Ensure main earth straps from engine block to chassis are clean and tight.

Other Faults on This Variant

DPF Blockage and Regeneration Failure

Moderate

2013-201730,000–80,000 miles£150–£1200

The 1.5 TDCi diesel Fiesta is commonly used for short urban trips — exactly the wrong usage for a DPF-equipped car. Blocked DPF is the number one complaint.

EGR Valve Failure and Intake Carbonisation

Moderate

2013-201740,000–90,000 miles£80–£350

EGR failure on the 1.5 TDCi Fiesta is a common companion to DPF issues. Carbon deposits block the valve and intake manifold, causing power loss and rough running.

Diesel Injector Failure and Rough Running

Severe

2013-201780,000–160,000 miles£200–£800

Common rail injectors on the 1.5 TDCi can fail, causing misfires, excessive smoke and hard starting. Injector failure can also result in diesel washing the cylinder walls, accelerating engine wear.
