2014 Renault Master — MOT failures & pass rate
Across 3,707 MOT tests, the 2014 Renault Master recorded an 82.4% pass rate. Vans of a similar age fail 23.1% of the time, so this is 5.5pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (10.6%) and brakes (9.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, rbt (sp) and position lamp — headlamp aim alone was recorded 147 times.
Mileage is the strongest signal on the record: 9.9% of 0-30k cars fail, rising to 25.8% once past 150k — 2.6× the risk.
Brakes is the most common advisory, noted on 23.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 15.2% of tests failed in 2021 against 19.9% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 23.1% | 855 |
| 2 | Tyres | 16.7% | 620 |
| 3 | Lighting & signalling | 10.4% | 384 |
| 4 | Suspension | 7.9% | 293 |
| 5 | Visibility | 6.3% | 235 |
| 6 | Other defects | 4.6% | 170 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 413 | 9.9% |
| 30-60k | 825 | 12.7% |
| 60-90k | 790 | 16.5% |
| 90-120k | 522 | 19.2% |
| 120-150k | 443 | 21.2% |
| 150k+ | 702 | 25.8% |

What to check before buying a 2014 Master
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 10.6% of tests. Start there.
- Lighting & signalling (10.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.0% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Visibility (3.8% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
