2018 Fiat Roller Team — MOT failures & pass rate
2,850 MOT tests on the 2018 Fiat Roller Team are in this dataset, and 93.5% of them passed. All cars of a similar age fail 11.0% of the time, so this is 4.5pp better than the group it competes with. Failures cluster in lighting & signalling, visibility and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 6.1% of all tests — 3.1 points clear of visibility, so it is the first thing to check.
At component level the recurring items are headlamp aim, wipers and outline marker lamp — headlamp aim alone was recorded 110 times.
Mileage matters less than usual here: the 2018 Roller Team fails 5.1% of the time in the 0-30k band and 8.9% at 60-90k, a spread of only 3.8 points.
Advisories point at the next bill rather than this one: tyres was flagged on 8.2% of tests without failing them.
The trend is worsening — 5.7% of tests failed in 2021 against 8.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2018 Roller Team
On a 2018 Roller Team, lighting & signalling is what the MOT record says goes wrong most — it appeared in 6.1% of tests. Check these areas before you commit.
- Lighting & signalling (6.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.0% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (1.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
