1999 Mercedes-Benz V-Class — MOT failures & pass rate
Across 523 MOT tests, the 1999 Mercedes-Benz V-Class recorded a 69.8% pass rate. MPVs of a similar age fail at 29.6%, so the 1999 V-Class sits squarely on the average. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (19.9%) and brakes (17.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp, component mounting prescribed areas and rbt (sp) — headlamp alone was recorded 68 times.
Mileage is the strongest signal on the record: 21.9% of 0-30k cars fail, rising to 32.1% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 45.5% of tests without failing them.
The trend is improving — the fail rate fell from 32.0% in 2021 to 28.6% in 2025, as the worst-kept examples leave the fleet.

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 | 45.5% | 238 |
| 2 | Suspension | 37.5% | 196 |
| 3 | Body, structure & corrosion | 27.9% | 146 |

| 5 | Other defects | 18.6% | 97 |
| 6 | Lighting & signalling | 15.7% | 82 |
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 | 41 | 21.9% |
| 60-90k | 66 | 25.8% |
| 90-120k | 103 | 28.2% |
| 120-150k | 120 | 33.3% |
| 150k+ | 106 | 32.1% |
Failure rate by age
By fuel type

What to check before buying a 1999 V-Class
On a 1999 V-Class, lighting & signalling is what the MOT record says goes wrong most — it appeared in 19.9% of tests. Check these areas before you commit.
- Lighting & signalling (19.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (17.6% 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.
- Suspension (13.8% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
