What the Master fails on

Share of failed tests with at least one fail item in each DVSA inspection section. A test can fail in several sections at once.

Is the Master getting worse?

The fail rate rose 1.7 points to 29.7% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 3.4 points, so it is holding up better than the fleet average for its age.

Fail rate is first attempts at class 4 tests. Median age is the age of a typical Master at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.

The exact defects that fail it

Every failure item DVSA recorded against a Master in 2025, counted by how many tests each one appeared on.

  1. 1Rbt (sp): efficiency below requirements898 tests
  2. 2Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt454 tests
  3. 3Position lamp: not working417 tests
  4. 4Ball joint: ball joint excessively worn415 tests
  5. 5Service brake performance: excessively binding406 tests
  6. 6Steering rack: gaiter missing or no longer prevents the ingress of dirt383 tests
  7. 7Wipers: does not clear the windscreen effectively377 tests
  8. 8Parking brake performance: inoperative on one side326 tests

What wears out first

Advisories are the tester flagging wear that is still legal. A typical Master collects 2.76 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.

  1. 1Brake discs: in such a condition that it is seriously weakened1,663 tests
  2. 2Tread depth: tread depth below requirements of 1.6mm1,279 tests
  3. 3Rigid brake pipes: excessively corroded1,210 tests
  4. 4Engine oil leaks: leaking excessively from engine1,144 tests

Questions

What is the Renault Master MOT pass rate?

72.6% of the 15,751 Renault Master first-attempt MOTs in 2025 passed. The fail rate of 27.4% compares with 22.6% across all cars. A further 6.2% passed after a defect was fixed during the test visit.

What does a Renault Master usually fail on?

The single most common failure is "Rbt (sp): efficiency below requirements", recorded on 898 failed tests, followed by "Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt" and "Position lamp: not working". By section, brakes appears in 49.3% of failures, lamps, reflectors and electrical equipment appears in 43.5% of failures, suspension appears in 28.3% of failures.

Does age change the odds?

Sharply. At 3 to 5 years old the fail rate was 16.1%; at 14+ years it was 36.1%. The median Renault Master tested in 2025 was 13 years old with 92,236 miles.

Is the Renault Master getting less reliable?

The fail rate rose 1.7 points to 29.7% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 3.4 points, so it is holding up better than the fleet average for its age.
