The exact defects that fail it
Every failure item DVSA recorded against a Motor in 2025, counted by how many tests each one appeared on.
- 1Wipers: does not clear the windscreen effectively41 tests
- 2Rbt (sp): efficiency below requirements34 tests
- 3Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength33 tests
- 4Position lamp: not working33 tests
- 5Horn: not working30 tests
- 6Rear fog lamp: not working28 tests
- 7Outline marker lamp: not working26 tests
- 8Service brake performance: excessively binding26 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Motor collects 2.84 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Brake discs: in such a condition that it is seriously weakened93 tests
- 2Engine oil leaks: leaking excessively from engine92 tests
- 3Rigid brake pipes: excessively corroded89 tests
- 4Condition: has a tear, caused by separation or partial failure of its structure89 tests
- 5Wheel bearings: has excessive play73 tests
- 6Tread depth: tread depth below requirements of 1.6mm55 tests
- 7Pipes and hoses: excessively corroded49 tests
- 8Chassis condition: corroded to the extent that the rigidity of the assembly is significantly reduced44 tests
