Symptoms

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.

- 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
Timing Chain Stretch and Rattle
SevereThe early EA111 1.2 TSI engines suffer from significant timing chain stretch, causing an aggressive cold start rattle and potential engine failure.
Turbo Actuator / Wastegate Failure
SevereThe electronic turbo actuator on the 1.2 TSI fails frequently. It controls the wastegate but often seizes or burns out internally.
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.
