Pre-MOT checklist for One owners

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

Check tread with the 20p test and inspect sidewalls for cracking — tyres close to the limit are the country’s most common advisory
Walk round with all lights on: one blown bulb is the most avoidable fail there is
Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
A blowing exhaust or visible smoke will fail; warm the engine fully before the test
Replace smeared wiper blades and top up washer fluid — both are test items

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.

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