Ford Focus Mk3 2.0 TDCi — Shock Absorber Oil Leak and Failure
Shock absorbers lose their damping efficiency over time, and eventually blow their seals, leaking hydraulic fluid.

Moderate
Est. Cost
£200–£400
OBD Codes
None
Suspension
Typical layout and location for the Suspension assembly.
Symptoms
- Car bounces multiple times after hitting a bump
- Visibly wet, oily residue running down the outside of the shock absorber body
- Increased body roll in corners and longer braking distances
Root Cause
The internal rubber seals wear out from millions of oscillations. Grit on the damper shaft accelerates the wear, tearing the seal.
How To Fix
- Perform a 'bounce test' on each corner of the car — it should settle immediately after one rebound.
- Replace dampers in axle pairs.
- Consider replacing top mounts and bump stops simultaneously to save on future labour.
- Cost: £200-400 per pair.

Other Faults on This Variant
Powershift Dual Clutch Gearbox Failure
CriticalThe 6-speed Powershift (MPS6/6DCT450) automatic gearbox is notoriously fragile. Internal plastic parts shatter, clogging the transmission filter.
Steering Rack Motor Failure (EPS)
CriticalThe Electronic Power Steering rack on the Mk3 Focus suffers from water ingress, causing the motor to short out.
DPF Vaporiser Failure
ModerateFord uses a 5th injector (vaporiser) in the exhaust to regenerate the DPF. This vaporiser clogs with soot, preventing regeneration.
