Petrol Fiat 500l: MOT pass rate
73.7% of petrol Fiat 500ls pass the MOT first time, measured across 5,515 DVSA tests on that fuel type alone. Average mileage at test was 57,023.
Petrol against the other Fiat 500l versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 68.7% | 11,925 |
| Petrol | 73.7% | 5,515 |
| All Fiat 500l | 70.3% | 17,443 |
Why the fuel type changes the number
Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.
On the Fiat 500l specifically, petrol is the strongest at 73.7%, and this petrol version sits 3.4 points above the 70.3% model average.
What it means if you are buying one
The petrol Fiat 500l is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Fiat 500l had covered 57,023 miles at test, against 74,465 for the diesel. That is around average, so condition and service history will tell you more than the odometer does.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Fiat 500l page separate age from fuel if you want to isolate one.
