What stands out

At 22 years, 17.3 of every 100 MOTs of the Peugeot 406 found a suspension fail (n=2,519), against 15.2 for all cars of that age (n=913,980).
It is above the all-car rate at every age with at least 1,000 tests (7 ages).
The gap is widest at 25 years: 15.3 per 100 MOTs against 12.8 for all cars.
The suspension fail item recorded most often at 22 years: component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength, on 5.8 per 100 MOTs.
The most common suspension advisory or minor defect: coil spring: corroded, on 9.8 per 100 MOTs.

Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

What to check on a viewing

On the Peugeot 406, the suspension items testers fail most are component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength; suspension ball joint worn; anti-roll bar link worn.

Listen for knocks or clonks over speed bumps and rough roads on the test drive.
Push down hard on each corner: the car should settle at once rather than keep bouncing.
Look behind the wheels for broken or heavily rusted coil springs and split rubber bushes.
Check that the car sits level and that no tyre is worn on one edge only.

Ask for the car's MOT history: a suspension advisory that repeats from year to year has not been fixed. GOV.UK MOT history.

Suspension problems on other Peugeot models

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

The all cars figures cover all class 4 vehicles (cars and light vans) tested at the same age.
