Pre-MOT checklist for 6 owners

Based on the failure profile above, ten minutes with a torch before your test removes the most likely fail items:

Bounce each corner and listen for clonks over speed bumps — suspension is this model’s (and the UK’s) top failure system
Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
Walk round with all lights on: one blown bulb is the most avoidable fail there is
Check tread with the 20p test and inspect sidewalls for cracking — tyres close to the limit are the country’s most common advisory
A blowing exhaust or visible smoke will fail; warm the engine fully before the test

Engine management light on?

An illuminated engine management light is a Major MOT defect. Read the code, repair the cause, then confirm the light stays off — clearing a code alone is not a repair.

Same-vehicle follow-up

The defect groups above are a single-year count. The prognosis registry follows the same vehicle_id into the next MOT year. The extracts do not record the repair, a turbo part number, or a gearbox type.

Suspension: advisory follow-up · did the same fail item hold
Brakes: advisory follow-up · did the same fail item hold
Tyres: advisory follow-up · did the same fail item hold
Noise, emissions and leaks: advisory follow-up · did the same fail item hold

On this model, these certificate lines have a published follow-up (cohort at least 200 cars):

Ball joint has slight play — 830 cars · 11.4% failed the same item the next year
Track rod end ball joint has slight play — 280 cars · 9.3% failed the same item the next year
Exhaust system has a minor leak of exhaust gases — 537 cars · 6.5% failed the same item the next year
Rigid brake pipes corroded, covered in grease or other material — 1,899 cars · 6.3% failed the same item the next year
