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

Electric Window Regulator Cable Failure

Minor

2004-201150,000–120,000 miles£100–£200

The cables inside the electric window regulator mechanism fray and snap, causing the window glass to drop into the door frame.

Engine Thermostat Sticking Open

Minor

2004-201160,000–120,000 miles£100–£250

The engine coolant thermostat fails in the 'open' position. The engine never reaches its optimal operating temperature, killing fuel economy.

Starter Motor Solenoid / Brush Wear

Severe

2004-201170,000–130,000 miles£150–£350

The starter motor wears out internally. This is particularly common on vehicles equipped with Stop/Start systems.
