2014 Fiat Doblo — MOT failures & pass rate
Across 39,279 MOT tests, the 2014 Fiat Doblo recorded a 77.0% pass rate. Vans of a similar age fail at 22.9%, so the 2014 Doblo sits squarely on the average. Failures cluster in suspension, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — suspension (13.6%) and lighting & signalling (12.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, headlamp aim and stop lamp — coil spring alone was recorded 2,777 times.
Condition tracks the odometer closely. Failures run at 14.7% in the 0-30k band and 28.9% in the 150k+ band, a 14.2-point spread.
Split by fuel, diesel examples fail 4.6pp more often than petrol ones (23.1% vs 18.6%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 24.2% of tests without failing them.
The trend is worsening — 19.6% of tests failed in 2021 against 26.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2014 Doblo
On a 2014 Doblo, suspension is what the MOT record says goes wrong most — it appeared in 13.6% of tests. Check these areas before you commit.
- Suspension (13.6% 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.
- Lighting & signalling (12.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.9% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
