Root Cause

The plastic spring retainers on the internal dampener break apart. The plastic fragments block the internal oil filter, destroying oil pressure to the mechatronic unit.

How To Fix

Requires full gearbox rebuild and replacement of the dampener assembly with upgraded metal spring retainers. Fluid MUST be changed every 37,500 miles. Cost: £1,800-£2,500

Other Faults on This Variant

Steering Rack Motor Failure (EPS)

Critical

2011-201850,000–120,000 miles£800–£1200

The Electronic Power Steering rack on the Mk3 Focus suffers from water ingress, causing the motor to short out.

DPF Vaporiser Failure

Moderate

2011-201860,000–110,000 miles£250–£350

Ford uses a 5th injector (vaporiser) in the exhaust to regenerate the DPF. This vaporiser clogs with soot, preventing regeneration.

Air Conditioning Condenser Leak (Stone Damage)

Minor

2011-201840,000–120,000 miles£250–£450

The air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
