Yes, a coil spring can fail an MOT in the UK if it is broken, cracked, insecure, badly corroded or incorrectly seated. This UK mechanic-style guide explains suspension warning signs, ride-height problems, tyre damage risks and common MOT failure points.
A coil spring can fail an MOT if it is snapped, cracked, insecure, badly corroded, incorrectly seated or likely to damage another component such as a tyre.
Broken coil springs are common MOT failures, especially on older vehicles and cars regularly driven over potholes, speed bumps or rough roads.
The coil spring helps hold the car at the correct ride height and keeps the tyre loaded properly on the road. If it breaks or moves out of its seat, the car may sit low, handle badly or damage nearby parts.
These are the spring defects that can become safety-related MOT failures.
A snapped or fractured coil spring can fail because it affects suspension safety.
Rust that seriously weakens the spring or mountings can be an MOT issue.
A spring that is not located properly in its seat can be unsafe.
One corner sitting low can suggest a broken or weakened spring.
A fractured spring end may damage a tyre, brake hose or nearby component.
Loose, displaced or unsafe suspension components can cause failure.
A spring does not always snap in the middle. A small end piece can break off and sit in the spring cup, which may only be noticed during inspection. You may hear a metallic twang, clunk or rattle after hitting a pothole.
If the car suddenly sits lower on one side after a bang or pothole, get the spring checked.
These checks can help spot a broken spring before the tester does.
Check whether one corner of the vehicle sits noticeably lower.
Clunks, bangs, rattles or metallic noises can point to spring or suspension faults.
If safe, look for a broken coil, loose spring end or unusual spring position.
A broken spring can cause the tyre to sit closer to bodywork or suspension parts.
Previous spring corrosion or suspension advisories may worsen later.
A garage can safely check spring condition, seating and related suspension parts.
Yes, if the spring is broken, cracked, insecure or causing the car to sit unevenly. A damaged spring can affect handling, braking stability and tyre clearance.
It is also sensible to check the matching spring on the same axle, shock absorbers, top mounts and anti-roll bar links, because suspension wear often appears in more than one place.
Springs often fail from corrosion, age, potholes or repeated impacts. When one breaks, check the spring seat, shock absorber, top mount, lower arm, tyre and brake hose area for damage or unusual contact.
Driving with a broken coil spring is not recommended. A broken spring can move out of position, damage a tyre or make the car unstable, especially on rough roads or during emergency braking.
If the car sits low, makes loud suspension noises, or a sharp spring end is close to the tyre, avoid driving and arrange recovery or inspection.
Not always, but many garages recommend checking or replacing springs in pairs on the same axle. If one spring has failed from age or corrosion, the matching spring may not be far behind.
Replacing both sides can help keep ride height and handling more even, especially on older cars.
If a used car has repeated MOT advisories for corroded springs, suspension wear or uneven ride height, budget for repairs. A car can pass today and still need suspension work soon.
Common questions UK drivers ask when a spring is broken, rusty, noisy or mentioned on an MOT advisory.
Yes. A broken, cracked or insecure coil spring can fail an MOT.
Yes, if corrosion seriously weakens the spring or affects suspension safety. Light surface rust alone may not fail.
Yes. Minor corrosion or early wear may be recorded as an advisory if it is not yet serious enough to fail.
Not always, but many garages recommend checking or replacing springs in pairs on the same axle for balanced ride height and handling.
Yes. A sharp or displaced spring can contact the tyre or nearby components, which can be dangerous.
If the car sits unevenly or makes suspension noises, have the springs and related suspension parts inspected before the test.
