Suspension advisory

Coil Spring Corroded MOT Advisory Cost

Corroded coil springs are common on older cars. The risk is that a spring can snap later and cause an MOT fail or roadside issue.

Typical UK cost

GBP 120-300 per spring, often more if top mounts or shocks are also worn

Buyer risk

Price it in

Negotiation note

Negotiate per axle if both sides are old or one side has already been replaced.

MOT wording this covers

Coil spring corroded
Road spring corroded

What it means

The tester saw corrosion on the suspension spring. It may still be intact, but corrosion weakens the spring over time.

Is it safe to drive?

Usually driveable as an advisory, but knocking, uneven ride height or a twanging noise when steering needs prompt inspection.

Should you buy a car with this advisory?

Check whether springs have been replaced in pairs. A single new spring on one side and an old corroded one on the other can mean another bill is coming.

Checks at a viewing

Check the car sits level on flat ground.
Listen for knocking or twanging noises when turning slowly.
Look for broken spring ends near the lower spring seat.

Garage checks

Ask the garage to inspect shocks, top mounts and drop links at the same time.
Ask whether replacement should be done in axle pairs.
