2004 Ci Motorhome Fiat — MOT failures & pass rate
282 MOT tests on the 2004 Ci Motorhome Fiat are in this dataset, and 73.8% of them passed. All cars of a similar age fail 27.7% of the time, so this is 1.5pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.9% of all tests — 3.5 points clear of brakes, so it is the first thing to check.
At component level the recurring items are service brake performance, component mounting prescribed areas and outline marker lamp — service brake performance alone was recorded 32 times.
Mileage is the strongest signal on the record: 20.7% of 0-30k cars fail, rising to 37.5% once past 60-90k.
Advisories point at the next bill rather than this one: body, structure & corrosion was flagged on 28.0% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Body, structure & corrosion | 28.0% | 79 |
| 2 | Brakes | 22.3% | 63 |

| 0-30k | 58 | 20.7% |
| 30-60k | 176 | 25.6% |
| 60-90k | 40 | 37.5% |
Failure rate by age
Trend over time

What to check before buying a 2004 Fiat
On a 2004 Fiat, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.9% of tests. Check these areas before you commit.
- Lighting & signalling (14.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.3% 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 (7.8% 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.
