Ford Fiesta Mk7 1.5 TDCi 75bhp — Shock Absorber Oil Leak and Failure
Shock absorbers lose their damping efficiency over time, and eventually blow their seals, leaking hydraulic fluid.
Severity
ModerateDIY Difficulty
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
DPF Blockage and Regeneration Failure
ModerateThe 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
ModerateEGR 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
SevereCommon 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.
