1990 BMW 7 Series — MOT failures & pass rate
Across 280 MOT tests, the 1990 BMW 7 Series recorded an 83.2% pass rate. Executive cars of a similar age fail 18.4% of the time, so this is 1.6pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.3% of tests against 8.6% for the next-worst category.
At component level the recurring items are headlamp aim, washers and position lamp — headlamp aim alone was recorded 14 times.
Condition tracks the odometer closely. Failures run at 5.3% in the 90-120k band and 25.7% in the 150k+ band, a 20.3-point spread — more than double.
Brakes is the most common advisory, noted on 30.0% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 17.5% in 2021 to 15.2% in 2025, as the worst-kept examples leave the fleet.

| 90-120k | 75 | 5.3% |
| 120-150k | 82 | 21.9% |
| 150k+ | 74 | 25.7% |
Trend over time

What to check before buying a 1990 7 Series
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.3% of tests. Start there.
- Lighting & signalling (14.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.6% 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.
- Visibility (7.1% 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.
