1989 BMW 7 Series — MOT failures & pass rate
Across 261 MOT tests, the 1989 BMW 7 Series recorded an 83.9% pass rate. Executive cars of a similar age fail 17.7% of the time, so this is 1.6pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 13.0% of tests against 6.1% for the next-worst category.
At component level the recurring items are position lamp, stop lamp and headlamp — position lamp alone was recorded 16 times.
A 150k+ example is materially riskier than a 60-90k one: 20.2% versus 12.5%.
Brakes is the most common advisory, noted on 23.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 12.5% of tests failed in 2021 against 14.0% 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 | 23.0% | 60 |
| 2 | Suspension | 20.3% | 53 |
| 3 | Emissions & environmental | 17.2% | 45 |

| 5 | Tyres | 11.5% | 30 |
| 6 | Other defects | 10.3% | 27 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 32 | 12.5% |
| 90-120k | 44 | 6.8% |
| 120-150k | 40 | 12.5% |
| 150k+ | 94 | 20.2% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 56 | 12.5% |
| 2022 | 54 | 18.5% |
| 2023 | 49 | 14.3% |
| 2024 | 52 | 21.1% |

What to check before buying a 1989 7 Series
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 13.0% of tests. Start there.
- Lighting & signalling (13.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (6.1% 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.
- Brakes (5.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
