1982 BMW 3 Series — MOT failures & pass rate
383 MOT tests on the 1982 BMW 3 Series are in this dataset, and 83.0% of them passed. Executive cars of a similar age fail at 17.0%, so the 1982 3 Series sits squarely on the average. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 11.0% of all tests — 3.4 points clear of brakes, so it is the first thing to check.
At component level the recurring items are service brake performance, position lamp and headlamp aim — service brake performance alone was recorded 17 times.
Mileage is the strongest signal on the record: 20.3% of 30-60k cars fail, rising to 10.0% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 17.0% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 30-60k | 69 | 20.3% |
| 60-90k | 124 | 19.4% |
| 90-120k | 97 | 18.6% |
| 120-150k | 44 | 9.1% |
| 150k+ | 40 | 10.0% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 139 | 15.8% |

What to check before buying a 1982 3 Series
On a 1982 3 Series, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.0% of tests. Check these areas before you commit.
- Lighting & signalling (11.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.6% 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 (5.0% 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.
