Symptoms
- Loud 'twang' or bang when turning the steering wheel at low speeds
- Car sits noticeably lower on one side
- Grating noise over bumps
Root Cause
The protective coating on the steel spring chips from stone impacts. Salt water corrodes the exposed steel, weakening the spring until it fractures under load.
How To Fix
- Visually inspect all four springs for fractures at the very bottom coil.
- Always replace coil springs in pairs across an axle to maintain handling balance.
- Cost: £150-300 per pair at an independent garage.

Other Faults on This Variant
High Pressure Fuel Pump Cam Follower Wear
CriticalThe PD (pumpe-düse) 2.0 TDI uses a mechanical cam follower to drive the high-pressure fuel pump. This follower wears rapidly and if not replaced destroys the camshaft — a £2,500 repair for a £15 part.
Dual Mass Flywheel Failure
SevereDMF failure on the Golf Mk5 2.0 TDI is a rite of passage for high-mileage cars. The flywheel absorbs diesel engine vibrations but wears out — often needing clutch replacement at the same time.
Gearbox Dogbone Mount Bush Failure
MinorThe lower engine pendulum mount (often called the dogbone mount) bushes perish, causing excessive engine movement, clunking, and sloppy gear changes.
