Bentley Arnage reliability and MOT pass rate
88% passed first time. The 12% fail rate is 10.6 points better than the all-car average, on a median example 23 years old with 57,492 miles.

Is the Arnage getting worse?
The fail rate rose 2.2 points to 12% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about -1.3 points, so it is getting worse faster than age explains.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 1,539 | 20 | 9.8% | 22.5% | |
| 2023 | 1,483 | 21 | 11.2% | 22.8% | |
| 2024 | 1,222 | 22 | 10.8% | 23.2% | |
| 2025 | 1,302 | 23 | 12% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Arnage 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 Arnage in 2025, counted by how many tests each one appeared on.
- 1Ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt34 tests
- 2Rbt (sp): efficiency below requirements21 tests
- 3SRS malfunction indicator lamp: warning lamp indicates a fault18 tests
- 4Malfunction indicator lamp: inoperative or indicates a malfunction12 tests
- 5Linkage ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt10 tests
- 6Anti-lock braking system: warning lamp indicates an ABS fault9 tests
- 7Position lamp: not working9 tests
- 8Rigid brake pipes: excessively corroded9 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Arnage collects 3.02 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 weakened94 tests
- 2Tread depth: tread depth below requirements of 1.6mm87 tests
- 3Rigid brake pipes: excessively corroded79 tests
- 4Engine oil leaks: leaking excessively from engine65 tests
- 5Condition: has a tear, caused by separation or partial failure of its structure63 tests
- 6Shock absorbers: has a serious fluid leak46 tests
- 7Coil spring: corroded so that its cross sectional area is reduced and seriously weakened35 tests
- 8Shock absorbers: has an excessively worn bush30 tests
Questions
What is the Bentley Arnage MOT pass rate?
88% of the 1,302 Bentley Arnage first-attempt MOTs in 2025 passed. The fail rate of 12% compares with 22.6% across all cars. A further 1.8% passed after a defect was fixed during the test visit.
What does a Bentley Arnage usually fail on?
The single most common failure is "Ball joint dust cover: ball joint dust cover no longer prevents the ingress of dirt", recorded on 34 failed tests, followed by "Rbt (sp): efficiency below requirements" and "SRS malfunction indicator lamp: warning lamp indicates a fault". By section, suspension appears in 46.8% of failures, brakes appears in 38.5% of failures, lamps, reflectors and electrical equipment appears in 29.5% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 0%; at 14+ years it was 12%. The median Bentley Arnage tested in 2025 was 23 years old with 57,492 miles.
Is the Bentley Arnage getting less reliable?
The fail rate rose 2.2 points to 12% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about -1.3 points, so it is getting worse faster than age explains.
