1989 Fiat Ducato — MOT failures & pass rate
The 1989 Fiat Ducato passed 66.8% of its 1,687 recorded MOT tests. Vans of a similar age fail 28.7% of the time, so this is 4.5pp 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 28.8% of all tests — 12.2 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 332 times.
Mileage is the strongest signal on the record: 22.6% of 0-30k cars fail, rising to 34.7% once past 150k.
Fuel type barely separates them — petrol fails 33.1% of the time against 33.5% for diesel.
Advisories point at the next bill rather than this one: brakes was flagged on 41.0% of tests without failing them.

What to check before buying a 1989 Ducato
On a 1989 Ducato, lighting & signalling is what the MOT record says goes wrong most — it appeared in 28.8% of tests. Check these areas before you commit.
- Lighting & signalling (28.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (16.6% 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.
- Body, structure & corrosion (15.7% 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.
