Most common reasons for failing

Share of all 486 tests where this item caused a failure.

  1. Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits5.8%
  2. Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength3.9%
  3. Anti-lock braking system: warning lamp indicates an ABS fault3.5%
  4. Catalyst emissions: carbon monoxide content at idle exceeds manufacturer's specified limits3.3%
  5. Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits2.5%
  6. Electronic stability control: warning lamp indicates a fault2.3%
  7. Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds default limits2.3%

Most common advisories

Not failures yet, but things the tester warned about.

  1. Rigid brake pipes: excessively corroded9.9%
  2. Tread depth below requirements of 1.6mm8.4%
  3. Tyres - condition: has a tear, caused by separation or partial failure of its structure8.2%
  4. Wheel bearings: has excessive play7.4%
  5. Coil spring: corroded so that its cross sectional area is reduced and seriously weakened6.6%

What this means if you are buying one

This model year does better than most cars its age, so it is a reasonable used buy on MOT record alone. Before buying, check the area that fails most: catalyst emissions: lambda reading after 2nd fast idle outside specified limits. Then look up the car's own MOT history on GOV.UK with its number plate, and look for repeat advisories.
