1990 Fiat Ducato — MOT failures & pass rate
Across 2,384 MOT tests, the 1990 Fiat Ducato recorded a 68.7% pass rate. Vans of a similar age fail 29.2% of the time, so this is 2.2pp worse than the group it competes with. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 24.8% of all tests — 9.4 points clear of brakes, so it is the first thing to check.
At component level the recurring items are headlamp, headlamp aim and service brake performance — headlamp alone was recorded 319 times.
Mileage is the strongest signal on the record: 28.4% of 30-60k cars fail, rising to 32.5% once past 150k.
Split by fuel, diesel examples fail 1.5pp more often than petrol ones (32.1% vs 30.6%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: suspension was flagged on 40.3% of tests without failing them.
The trend is improving — the fail rate fell from 33.2% in 2021 to 30.9% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 1990 Ducato
On a 1990 Ducato, lighting & signalling is what the MOT record says goes wrong most — it appeared in 24.8% of tests. Check these areas before you commit.
- Lighting & signalling (24.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (15.4% 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.
- Body, structure & corrosion (14.3% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
