Toyota Yaris Mk2 1.3 VVT-i 87bhp — 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
Water Pump Leak and Bearing Failure
ModerateWhile incredibly reliable, the 1.3 VVT-i engine's most common weak point is the water pump, which develops a leak and noisy bearing.
MMT Semi-Automatic Gearbox Actuator Failure
CriticalModels fitted with the Multi-Mode Transmission (MMT) — an automated manual — suffer from severe actuator wear, causing the car to drop into neutral while driving.
Air Conditioning Condenser Leak (Stone Damage)
MinorThe 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.
