1998 Fiat Ducato — MOT failures & pass rate
The 1998 Fiat Ducato passed 71.5% of its 7,396 recorded MOT tests. That is 1.1 percentage points better than vans of a similar age, which fail at 29.6%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 18.9% of all tests — 6.6 points clear of brakes, so it is the first thing to check.
At component level the recurring items are component mounting prescribed areas, service brake performance and washers — component mounting prescribed areas alone was recorded 773 times.
A 150k+ example is materially riskier than a 0-30k one: 36.3% versus 21.5%.
Advisories point at the next bill rather than this one: suspension was flagged on 40.6% of tests without failing them.

What to check before buying a 1998 Ducato
On a 1998 Ducato, lighting & signalling is what the MOT record says goes wrong most — it appeared in 18.9% of tests. Check these areas before you commit.
- Lighting & signalling (18.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (12.3% 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 (11.4% 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.
