2000 Vauxhall Omega — MOT failures & pass rate
887 MOT tests on the 2000 Vauxhall Omega are in this dataset, and 77.1% of them passed. That is effectively the same as executive cars of a similar age (23.7% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in suspension, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — suspension (10.6%) and lighting & signalling (9.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, catalyst emissions and headlamp aim — component mounting prescribed areas alone was recorded 82 times.
Mileage is the strongest signal on the record: 17.2% of 30-60k cars fail, rising to 22.4% once past 150k.
Brakes is the most common advisory, noted on 35.6% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 23.1% in 2021 to 20.6% in 2025, as the worst-kept examples leave the fleet.

Most common specific failures
The exact components most often recorded as failures — more specific than the categories above.
| # | Failure item | Times recorded |
|---|---|---|
| 1 | Component mounting prescribed areas | 82 |
| 2 | Catalyst emissions | 62 |
| 3 | Headlamp aim | 44 |
| 4 | Rigid brake pipes | 38 |

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 | 35.6% | 316 |
| 2 | Suspension | 26.9% | 239 |
| 3 | Emissions & environmental | 24.5% | 217 |
| 4 | Tyres | 23.8% | 211 |
| 5 | Body, structure & corrosion | 20.9% | 185 |
| 6 | Lighting & signalling | 11.3% | 100 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 93 | 17.2% |
| 60-90k | 204 | 18.6% |
| 90-120k | 305 | 26.9% |
| 120-150k | 151 | 25.8% |
| 150k+ | 125 | 22.4% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |

What to check before buying a 2000 Omega
The failure pattern for this year is specific enough to inspect against: suspension accounted for 10.6% of tests. Start there.
- Suspension (10.6% 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.
- Lighting & signalling (9.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (7.4% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
