2020 Mercedes-Benz Eqv 300 + — MOT failures & pass rate
448 MOT tests on the 2020 Mercedes-Benz Eqv 300 + are in this dataset, and 90.8% of them passed. That is effectively the same as all cars of a similar age (8.9% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, body, structure & corrosion and brakes.
What the MOT record shows
One area stands out: tyres, recorded in 5.8% of tests against 2.0% for the next-worst category.
At component level the recurring items are joints, ball joint and rbt (sp) — joints alone was recorded 9 times.
Mileage is the strongest signal on the record: 5.0% of 0-30k cars fail, rising to 13.3% once past 90-120k — 2.7× the risk.
Tyres is the most common advisory, noted on 15.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 2.0% of tests failed in 2022 against 9.8% 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 | Tyres | 15.2% | 68 |
| 2 | Other defects | 3.1% | 14 |
| 3 | Suspension | 2.7% | 12 |
| 4 | Brakes | 2.7% | 12 |
| 5 | Visibility | 1.6% | 7 |
| 6 | Body, structure & corrosion | 0.9% | 4 |
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 | 161 | 5.0% |
| 30-60k | 150 | 11.3% |
| 60-90k | 78 | 12.8% |
| 90-120k | 30 | 13.3% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2022 | 51 | 2.0% |
| 2023 | 118 | 8.5% |
| 2024 | 132 | 12.1% |
| 2025 | 132 | 9.8% |
What to check before buying a 2020 Eqv 300 +
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.8% of tests. Start there.
- Tyres (5.8% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Body, structure & corrosion (2.0% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Brakes (1.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
