1984 Volkswagen Transporter — MOT failures & pass rate
Across 3,073 MOT tests, the 1984 Volkswagen Transporter recorded a 71.8% pass rate. Vans of a similar age fail at 28.7%, so the 1984 Transporter sits squarely on the average. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 18.0% of all tests — 3.4 points clear of suspension, so it is the first thing to check.
At component level the recurring items are component mounting prescribed areas, headlamp aim and washers — component mounting prescribed areas alone was recorded 352 times.
Mileage matters less than usual here: the 1984 Transporter fails 27.9% of the time in the 0-30k band and 24.9% at 150k+, a spread of only 3.0 points.
Fuel type barely separates them — petrol fails 28.2% of the time against 28.4% for diesel.
Advisories point at the next bill rather than this one: suspension was flagged on 38.3% of tests without failing them.

What to check before buying a 1984 Transporter
On a 1984 Transporter, lighting & signalling is what the MOT record says goes wrong most — it appeared in 18.0% of tests. Check these areas before you commit.
- Lighting & signalling (18.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.6% 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 (12.0% 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.
