1981 Volkswagen Transporter — MOT failures & pass rate
Across 654 MOT tests, the 1981 Volkswagen Transporter recorded a 67.1% pass rate. That is 2.7 percentage points worse than vans of a similar age, which fail at 30.2%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 20.5% of tests against 15.6% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, position lamp and headlamp aim — component mounting prescribed areas alone was recorded 97 times.
A 150k+ example is materially riskier than a 0-30k one: 27.3% versus 36.6%.
Suspension is the most common advisory, noted on 38.5% of tests — work that passed today but is likely due soon.

| 90-120k | 64 | 31.3% |
| 150k+ | 44 | 27.3% |
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 561 | 32.4% |
| Diesel | 93 | 35.5% |

What to check before buying a 1981 Transporter
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 20.5% of tests. Start there.
- Lighting & signalling (20.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (15.6% 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.
- Brakes (13.8% 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.
