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.
